624b85e646 ath79: add support for Devolo dLAN pro 1200+ WiFi ac
This patch adds support for the Devolo dLAN pro 1200+ WiFi ac.
This device is a plc wifi AC2400 router/extender with 2 Ethernet ports,
has a QCA7500 PLC and uses the HomePlug AV2 standard.

Other than the PLC the hardware is identical to the Devolo Magic 2 WIFI.
Therefore it uses the same dts, which was moved to a dtsi to be included
by both boards.

This is a board that was previously included in the ar71xx tree.

Hardware:
   SoC:         AR9344
   CPU:         560 MHz
   Flash:       16 MiB (W25Q128JVSIQ)
   RAM:         128 MiB DDR2
   Ethernet:    2xLAN 10/100/1000
   PLC:         QCA75000 (Qualcomm HPAV2)
   PLC Uplink:  1Gbps MIMO
   PLC Link:    RGMII 1Gbps (WAN)
   WiFi:        Atheros AR9340 2.4GHz 802.11bgn
                Atheros AR9882-BR4A 5GHz 802.11ac
   Switch:      QCA8337, Port0:CPU, Port2:PLC, Port3:LAN1, Port4:LAN2
   Button:      3x Buttons (Reset, wifi and plc)
   LED:         3x Leds (wifi, plc white, plc red)
   GPIO Switch: 11-PLC Pairing (Active Low)
                13-PLC Enable
                21-WLAN power

MACs Details verified with the stock firmware:
   Radio1: 2.4 GHz &wmac     *:4c Art location: 0x1002
   Radio0: 5.0 GHz &pcie     *:4d Art location: 0x5006
   Ethernet        &ethernet *:4e = 2.4 GHz + 2
   PLC uplink      ---       *:4f = 2.4 GHz + 3
Label MAC address is from PLC uplink

The Powerline (PLC) interface of the dLAN pro 1200+ WiFi ac requires 3rd
party firmware which is not available from standard OpenWrt package
feeds. There is a package feed on github which you must add to
OpenWrt buildroot so you can build a firmware image which supports the
plc interface.

See: https://github.com/0xFelix/dlan-openwrt (forked from Devolo and
added compatibility for OpenWrt 21.02)

Flash instruction (TFTP):
 1. Set PC to fixed ip address 192.168.0.100
 2. Download the sysupgrade image and rename it to uploadfile
 3. Start a tftp server with the image file in its root directory
 4. Turn off the router
 5. Press and hold Reset button
 6. Turn on router with the reset button pressed and wait ~15 seconds
 7. Release the reset button and after a short time
    the firmware should be transferred from the tftp server
 8. Allow 1-2 minutes for the first boot.

6f648ed7e6 treewide: remove "+" sign for increment with macaddr_add
Many people appear to use an unneeded "+" prefix for the increment
when calculating a MAC address with macaddr_add. Since this is not
required and used inconsistently [*], just remove it.

[*] As a funny side-fact, copy-pasting has led to almost all
    hotplug.d files using the "+", while nearly all of the
    02_network files are not using it.

The tool ap51-flash (https://github.com/ap51-flash/ap51-flash) should be
used to transfer the image to the u-boot when the device boots up.

initramfs from TFTP
-------------------

The serial console must be used to access the u-boot shell during bootup.
It can then be used to first boot up the initramfs image from a TFTP server
(here with the IP 192.168.1.21):

   setenv serverip 192.168.1.21
   setenv ipaddr 192.168.1.1
   tftpboot 0c00000 <filename-of-initramfs-kernel>.bin && bootm $fileaddr

The actual sysupgrade image can then be transferred (on the LAN port) to the
device via

  scp <filename-of-squashfs-sysupgrade>.bin root@192.168.1.1:/tmp/

On the device, the sysupgrade must then be started using

  sysupgrade -n /tmp/<filename-of-squashfs-sysupgrade>.bin

4f07966696 ath79: add support for COMFAST CF-E375AC
COMFAST CF-E375AC is a ceiling mount AP with PoE support,
based on Qualcomm/Atheros QCA9563 + QCA9886 + QCA8337.

Short specification:

    2x 10/100/1000 Mbps Ethernet, with PoE support
    128MB of RAM (DDR2)
    16 MB of FLASH
    3T3R 2.4 GHz, 802.11b/g/n
    2T2R 5 GHz, 802.11ac/n/a, wave 2
    built-in 5x 3 dBi antennas
    output power (max): 500 mW (27 dBm)
    1x RGB LED, 1x button
    built-in watchdog chipset

Flash instruction:
1) Original firmware is based on OpenWrt.
Use sysupgrade image directly in vendor GUI.

2) TFTP
2.1) Set a tftp server on your machine with a fixed IP address of
     192.168.1.10. A place the sysupgrade as firmware_auto.bin.
2.2) boot the device with an ethernet connection on fixed ip route
2.3) wait a few seconds and try to login via ssh

3) TFTP trough Bootloader
3.1) open the device case and get a uart connection working
3.2) stop the autoboot process and test connection with serverip
3.3) name the sysupgrade image firmware.bin and run firmware_upg

MAC addresses:
Though the OEM firmware has four adresses in the usual locations,
it appears that the assigned addresses are just incremented in a
different way:

interface    address    location
LAN:          *:DC      0x0
WAN           *:DD      0x1002
WLAN 2.4g     *:E6      n/a (0x0 + 10)
WLAN 5g       *:DE      0x6
unused        *:DF      0x5006

The MAC address pointed at the label is the one assign to the LAN
interface.

The original setup fails to trigger ART calibration data
extraction for the AR9287. Instead, it would only have extracted
calibration data for an internal WMAC chip which is not present on
this board.

dc4745da7a ath79: add support for D-Link DAP-3662 A1
Specifications:
 * QCA9557, 16 MiB Flash, 128 MiB RAM, 802.11n 2T2R
 * QCA9882, 802.11ac 2T2R
 * 2x Gigabit LAN (1x 802.11af PoE)
 * IP68 pole-mountable outdoor case

Installation:
 * Factory Web UI is at 192.168.0.50
   login with 'admin' and blank password, flash factory.bin
 * Recovery Web UI is at 192.168.0.50
   connect network cable, hold reset button during power-on and keep it
   pressed until uploading has started (only required when checksum is ok,
   e.g. for reverting back to oem firmware), flash factory.bin

After flashing factory.bin, additional free space can be reclaimed by
flashing sysupgrade.bin, since the factory image requires some padding
to be accepted for upgrading via OEM Web UI.

Both ethernet ports are set to LAN by default, matching the labelling on
the case. However, since both GMAC Interfaces eth0 and eth1 are connected
to the switch (QCA8337), the user may create an additional 'wan' interface
as desired and override the vlan id settings to map br-lan / wan to either
the PoE or non-PoE port, depending on the individual scenario of use.

So, the LAN and WAN ports would then be connected to different GMACs, e.g.

config interface 'lan'
	option ifname 'eth0.1'
	...

config interface 'wan'
	option ifname 'eth1.2'
	...

config switch_vlan
        option device 'switch0'
        option vlan '1'
        option ports '1 0t'

config switch_vlan
        option device 'switch0'
        option vlan '2'
        option ports '2 6t'

55d2db0e8c ath79: add support for Meraki MR12
Port device support for Meraki MR12 from the ar71xx target to ath79.

Specifications:

  - SoC: AR7242-AH1A CPU
  - RAM: 64MiB (NANYA NT5DS32M16DS-5T)
  - NOR Flash: 16MiB (MXIC MX25L12845EMI-10G)
  - Ethernet: 1 x PoE Gigabit Ethernet Port (SoC MAC + AR8021-BL1E PHY)
  - Ethernet: 1 x 100Mbit port (SoC MAC+PHY)
  - Wi-Fi: Atheros AR9283-AL1A (2T2R, 11n)

Installation:

  1. Requires TFTP server at 192.168.1.101, w/ initramfs & sysupgrade .bins
  2. Open shell case
  3. Connect a USB->TTL cable to headers furthest from the RF shield
  4. Power on the router; connect to U-boot over 115200-baud connection
  5. Interrupt U-boot process to boot Openwrt by running:
       setenv bootcmd bootm 0xbf0a0000; saveenv;
       tftpboot 0c00000 <filename-of-initramfs-kernel>.bin;
       bootm 0c00000;
  6. Copy sysupgrade image to /tmp on MR12
  7. sysupgrade /tmp/<filename-of-sysupgrade>.bin

Notes:

  - kmod-owl-loader is still required to load the ART partition into the
    driver.

  - The manner of storing MAC addresses is updated from ar71xx; it is
    at 0x66 of the 'config' partition, where it was discovered that the
    OEM firmware stores it. This is set as read-only. If you are
    migrating from ar71xx and used the method mentioned above to
    upgrade, use kmod-mtd-rw or UCI to add the MAC back in. One more
    method for doing this is described below.

  - Migrating directly from ar71xx has not been thoroughly tested, but
    one method has been used a couple of times with good success,
    migrating 18.06.2 to a full image produced as of this commit. Please
    note that these instructions are only for experienced users, and/or
    those still able to open their device up to flash it via the serial
    headers should anything go wrong.

    1) Install kmod-mtd-rw and uboot-envtools
    2) Run `insmod mtd-rw.ko i_want_a_brick=1`
    3) Modify /etc/fw_env.config to point to the u-boot-env partition.
       The file /etc/fw_env.config should contain:

       # MTD device   env offset  env size    sector size
       /dev/mtd1      0x00000     0x10000     0x10000

       See https://openwrt.org/docs/techref/bootloader/uboot.config
       for more details.

    4) Run `fw_printenv` to verify everything is correct, as per the
       link above.
    5) Run `fw_setenv bootcmd bootm 0xbf0a0000` to set a new boot address.
    6) Manually modify /lib/upgrade/common.sh's get_image function:
       Change ...

       cat "$from" 2>/dev/null | $cmd

       ... into ...

       (
         dd if=/dev/zero bs=1 count=$((0x66)) ; # Pad the first 102 bytes
         echo -ne '\x00\x18\x0a\x12\x34\x56'  ; # Add in MAC address
         dd if=/dev/zero bs=1 count=$((0x20000-0x66-0x6)) ; # Pad the rest
         cat "$from" 2>/dev/null
       ) | $cmd

       ... which, during the upgrade process, will pad the image by
       128K of zeroes-plus-MAC-address, in order for the ar71xx's
       firmware partition -- which starts at 0xbf080000 -- to be
       instead aligned with the ath79 firmware partition, which
       starts 128K later at 0xbf0a0000.

    7) Copy the sysupgrade image into /tmp, as above
    8) Run `sysupgrade -F /tmp/<sysupgrade>.bin`, then wait

    Again, this may BRICK YOUR DEVICE, so make *sure* to have your
    serial cable handy.

96017a6013 ath79: add support for Senao Engenius EAP1200H
FCC ID: A8J-EAP1200H

Engenius EAP1200H is an indoor wireless access point with
1 Gb ethernet port, dual-band wireless,
internal antenna plates, and 802.3at PoE+

**Specification:**

  - QCA9557 SOC
  - QCA9882 WLAN	PCI card, 5 GHz, 2x2, 26dBm
  - AR8035-A PHY	RGMII GbE with PoE+ IN
  - 40 MHz clock
  - 16 MB FLASH		MX25L12845EMI-10G
  - 2x 64 MB RAM	NT5TU32M16FG
  - UART at J10		populated
  - 4 internal antenna plates (5 dbi, omni-directional)
  - 5 LEDs, 1 button (power, eth0, 2G, 5G, WPS) (reset)

**MAC addresses:**

  MAC addresses are labeled as ETH, 2.4G, and 5GHz
  Only one Vendor MAC address in flash

  eth0 ETH  *:a2 art 0x0
  phy1 2.4G *:a3 ---
  phy0 5GHz *:a4 ---

**Serial Access:**

  the RX line on the board for UART is shorted to ground by resistor R176
  therefore it must be removed to use the console
  but it is not necessary to remove to view boot log

  optionally, R175 can be replaced with a solder bridge short

  the resistors R175 and R176 are next to the UART RX pin at J10

**Installation:**

  2 ways to flash factory.bin from OEM:

  Method 1: Firmware upgrade page:

    OEM webpage at 192.168.1.1
    username and password "admin"
    Navigate to "Firmware Upgrade" page from left pane
    Click Browse and select the factory.bin image
    Upload and verify checksum
    Click Continue to confirm and wait 3 minutes

  Method 2: Serial to load Failsafe webpage:

    After connecting to serial console and rebooting...
    Interrupt uboot with any key pressed rapidly
    execute `run failsafe_boot` OR `bootm 0x9fd70000`
    wait a minute
    connect to ethernet and navigate to
    "192.168.1.1/index.htm"
    Select the factory.bin image and upload
    wait about 3 minutes

**Return to OEM:**

  If you have a serial cable, see Serial Failsafe instructions
  otherwise, uboot-env can be used to make uboot load the failsafe image

  *DISCLAIMER*
  The Failsafe image is unique to Engenius boards.
  If the failsafe image is missing or damaged this will brick the device
  DO NOT downgrade to ar71xx this way, it can cause kernel loop or halt

  ssh into openwrt and run
  `fw_setenv rootfs_checksum 0`
  reboot, wait 3 minutes
  connect to ethernet and navigate to 192.168.1.1/index.htm
  select OEM firmware image from Engenius and click upgrade

**TFTP recovery:**

  Requires serial console, reset button does nothing

  rename initramfs to 'vmlinux-art-ramdisk'
  make available on TFTP server at 192.168.1.101
  power board, interrupt boot
  execute tftpboot and bootm 0x81000000

  NOTE: TFTP is not reliable due to bugged bootloader
  set MTU to 600 and try many times

**Format of OEM firmware image:**

  The OEM software of EAP1200H is a heavily modified version
  of Openwrt Kamikaze. One of the many modifications
  is to the sysupgrade program. Image verification is performed
  simply by the successful ungzip and untar of the supplied file
  and name check and header verification of the resulting contents.
  To form a factory.bin that is accepted by OEM Openwrt build,
  the kernel and rootfs must have specific names...

    openwrt-ar71xx-generic-eap1200h-uImage-lzma.bin
    openwrt-ar71xx-generic-eap1200h-root.squashfs

  and begin with the respective headers (uImage, squashfs).
  Then the files must be tarballed and gzipped.
  The resulting binary is actually a tar.gz file in disguise.
  This can be verified by using binwalk on the OEM firmware images,
  ungzipping then untaring.

  Newer EnGenius software requires more checks but their script
  includes a way to skip them, otherwise the tar must include
  a text file with the version and md5sums in a deprecated format.

  The OEM upgrade script is at /etc/fwupgrade.sh.

  OKLI kernel loader is required because the OEM software
  expects the kernel to be no greater than 1536k
  and the factory.bin upgrade procedure would otherwise
  overwrite part of the kernel when writing rootfs.

Note on PLL-data cells:

  The default PLL register values will not work
  because of the external AR8035 switch between
  the SOC and the ethernet port.

  For QCA955x series, the PLL registers for eth0 and eth1
  can be see in the DTSI as 0x28 and 0x48 respectively.
  Therefore the PLL registers can be read from uboot
  for each link speed after attempting tftpboot
  or another network action using that link speed
  with `md 0x18050028 1` and `md 0x18050048 1`.

  The clock delay required for RGMII can be applied
  at the PHY side, using the at803x driver `phy-mode`.
  Therefore the PLL registers for GMAC0
  do not need the bits for delay on the MAC side.
  This is possible due to fixes in at803x driver
  since Linux 5.1 and 5.3

The serial console must be used to access the u-boot shell during bootup.
It can then be used to first boot up the initramfs image from a TFTP server
(here with the IP 192.168.1.21):

   setenv serverip 192.168.1.21
   setenv ipaddr 192.168.1.1
   tftpboot 0c00000 <filename-of-initramfs-kernel>.bin && bootm $fileaddr

The actual sysupgrade image can then be transferred (on the LAN port) to the
device via

  scp <filename-of-squashfs-sysupgrade>.bin root@192.168.1.1:/tmp/

On the device, the sysupgrade must then be started using

  sysupgrade -n /tmp/<filename-of-squashfs-sysupgrade>.bin

591a4c9ed3 ath79: Add support for Ubiquiti Bullet AC
CPU:         Atheros AR9342 rev 3 SoC
RAM:         64 MB DDR2
Flash:       16 MB NOR SPI
WLAN 2.4GHz: Atheros AR9342 v3 (ath9k)
WLAN 5.0GHz: QCA988X
Ports:       1x GbE

Flashing procedure is identical to other ubnt devices.
https://openwrt.org/toh/ubiquiti/common

Flashing through factory firmware
1. Ensure firmware version v8.7.0 is installed.
   Up/downgrade to this exact version.
2. Patch fwupdate.real binary using
   `hexdump -Cv /bin/ubntbox | sed 's/14 40 fe 27/00 00 00 00/g' | \
    hexdump -R > /tmp/fwupdate.real`
3. Make the patched fwupdate.real binary executable using
   `chmod +x /tmp/fwupdate.real`
4. Copy the squashfs factory image to /tmp on the device
5. Flash OpenWrt using `/tmp/fwupdate.real -m <squashfs-factory image>`
6. Wait for the device to reboot
(copied from Ubiquiti NanoBeam AC and modified)

Flashing from serial console
1. Connect serial console (115200 baud)
2. Connect ethernet to a network with a TFTP server, through a
   passive PoE injector.
3. Press a key to obtain a u-boot prompt
4. Set your TFTP server's ip address, with:
   setenv serverip <tftp-server-address>
5. Set the Bullet AC's ip address, with:
   setenv ipaddr <bullet-ac-address>
6. Set the boot file, with:
   setenv bootfile <name-of-initramfs-binary-on-tftp-server>
7. Fetch the binary with tftp:
   tftpboot
8. Boot the initramfs binary:
   bootm
9. From the initramfs, fetch the sysupgrade binary, and flash it with
   sysupgrade.

The Bullet AC is identified as a 2WA board by Ubiquiti. As such, the UBNT_TYPE
must match from the "Flashing through factory firmware" install instructions
to work.

Phy0 is QCA988X which can tune either band (2.4 or 5GHz). Phy1 is AR9342,
on which 5GHz is disabled.  It isn't currently known whether phy1 is
routed to the N connector at all.

0070650df4 ath79: move small-flash Engenius boards to tiny
This moves some of the Engenius boards from generic to tiny:

 - EAP350 v1
 - ECB350 v1
 - ENH202 v1

For these, factory.bin builds are already failing on master
branch because of the unique situation for these boards:

 - 8 MB flash
 - an extra "failsafe" image for recovery
 - TFTP does not work (barely possible with 600 MTU)
 - bootloader loads image from a longer flash offset
 - 1 eraseblock each needed for OKLI kernel loader and fake rootfs
 - using mtd-concat to make use of remaining space...

The manual alternative would be removing the failsafe partition.
However this comes with the risk of extremely difficult recovery
if a flash ever fails because TFTP on the bootloader is bugged.

FCC ID: U2M-EAP350

Engenius EAP350 is a wireless access point with 1 gigabit PoE ethernet port,
2.4 GHz wireless, external ethernet switch, and 2 internal antennas.

Specification:

  - AR7242 SOC
  - AR9283 WLAN			(2.4 GHz, 2x2, PCIe on-board)
  - AR8035-A switch		(GbE with 802.3af PoE)
  - 40 MHz reference clock
  - 8 MB FLASH			MX25L6406E
  - 32 MB RAM			EM6AA160TSA-5G
  - UART at J2			(populated)
  - 3 LEDs, 1 button		(power, eth, 2.4 GHz) (reset)
  - 2 internal antennas

MAC addresses:

  MAC address is labeled as "MAC"
  Only 1 address on label and in flash
  The OEM software reports these MACs for the ifconfig

  eth0	MAC	*:0c	art 0x0
  phy0	---	*:0d	---

Installation:

  2 ways to flash factory.bin from OEM:

  - if you get Failsafe Mode from failed flash:
      only use it to flash Original firmware from Engenius
      or risk kernel loop or halt which requires serial cable

  Method 1: Firmware upgrade page:

    OEM webpage at 192.168.10.1
    username and password "admin"
    Navigate to "Upgrade Firmware" page from left pane
    Click Browse and select the factory.bin image
    Upload and verify checksum
    Click Continue to confirm and wait 3 minutes

  Method 2: Serial to load Failsafe webpage:

    After connecting to serial console and rebooting...
    Interrupt uboot with any key pressed rapidly
    execute `run failsafe_boot` OR `bootm 0x9f670000`
    wait a minute
    connect to ethernet and navigate to
    "192.168.1.1/index.htm"
    Select the factory.bin image and upload
    wait about 3 minutes

Return to OEM:

  If you have a serial cable, see Serial Failsafe instructions
  otherwise, uboot-env can be used to make uboot load the failsafe image

  *DISCLAIMER*
  The Failsafe image is unique to Engenius boards.
  If the failsafe image is missing or damaged this will not work
  DO NOT downgrade to ar71xx this way, it can cause kernel loop or halt

  ssh into openwrt and run
  `fw_setenv rootfs_checksum 0`
  reboot, wait 3 minutes
  connect to ethernet and navigate to 192.168.1.1/index.htm
  select OEM firmware image from Engenius and click upgrade

Format of OEM firmware image:

  The OEM software of EAP350 is a heavily modified version
  of Openwrt Kamikaze. One of the many modifications
  is to the sysupgrade program. Image verification is performed
  simply by the successful ungzip and untar of the supplied file
  and name check and header verification of the resulting contents.
  To form a factory.bin that is accepted by OEM Openwrt build,
  the kernel and rootfs must have specific names...

    openwrt-senao-eap350-uImage-lzma.bin
    openwrt-senao-eap350-root.squashfs

  and begin with the respective headers (uImage, squashfs).
  Then the files must be tarballed and gzipped.
  The resulting binary is actually a tar.gz file in disguise.
  This can be verified by using binwalk on the OEM firmware images,
  ungzipping then untaring.

  The OEM upgrade script is at /etc/fwupgrade.sh

  Later models in the EAP series likely have a different platform
  and the upgrade and image verification process differs.

  OKLI kernel loader is required because the OEM software
  expects the kernel to be no greater than 1024k
  and the factory.bin upgrade procedure would
  overwrite part of the kernel when writing rootfs.

Note on PLL-data cells:

  The default PLL register values will not work
  because of the external AR8035-A switch between
  the SOC and the ethernet PHY chips.

  For AR724x series, the PLL register for GMAC0
  can be seen in the DTSI as 0x2c.
  Therefore the PLL register can be read from uboot
  for each link speed after attempting tftpboot
  or another network action using that link speed
  with `md 0x1805002c 1`.

  uboot did not have a good value for 1 GBps
  so it was taken from other similar DTS file.

Tested from master, all link speeds functional

  and name check and header verification of the resulting contents.
  To form a factory.bin that is accepted by OEM Openwrt build,
  the kernel and rootfs must have specific names...

    openwrt-senao-ecb600-uImage-lzma.bin
    openwrt-senao-ecb600-root.squashfs

  and begin with the respective headers (uImage, squashfs).
  Then the files must be tarballed and gzipped.
  The resulting binary is actually a tar.gz file in disguise.
  This can be verified by using binwalk on the OEM firmware images,
  ungzipping then untaring.

  The OEM upgrade script is at /etc/fwupgrade.sh

  Later models in the ECB series likely have a different platform
  and the upgrade and image verification process differs.

  OKLI kernel loader is required because the OEM software
  expects the kernel to be no greater than 1536k
  and the factory.bin upgrade procedure would
  overwrite part of the kernel when writing rootfs.

Note on PLL-data cells:

  The default PLL register values will not work
  because of the external AR8035-A switch between
  the SOC and the ethernet PHY chips.

  For AR934x series, the PLL register for GMAC0
  can be seen in the DTSI as 0x2c.
  Therefore the PLL register can be read from uboot
  for each link speed after attempting tftpboot
  or another network action using that link speed
  with `md 0x1805002c 1`.

  Unfortunately uboot did not have the best values
  so they were taken from other similar DTS files.

Tested from master, all link speeds functional

Engenius EnStationAC v1 is an outdoor wireless access point/bridge with
2 gigabit ethernet ports on 2 external ethernet switches,
5 GHz only wireless, internal antenna plates, and proprietery PoE.

Specification:

  - QCA9557 SOC
  - QCA9882 WLAN		(PCI card, 5 GHz, 2x2, 26dBm)
  - AR8035-A switch		(RGMII GbE with PoE+ IN)
  - AR8031 switch		(SGMII GbE with PoE OUT)
  - 40 MHz reference clock
  - 16 MB FLASH			MX25L12845EMI-10G
  - 2x 64 MB RAM		NT5TU32M16FG
  - UART at J10			(unpopulated)
  - internal antenna plates	(19 dbi, directional)
  - 7 LEDs, 1 button		(power, eth, wlan, RSSI) (reset)

MAC addresses:

  MAC addresses are labeled as ETH and 5GHz
  Vendor MAC addresses in flash are duplicate

  eth0	ETH	*:d3	art 0x0/0x6
  eth1	----	*:d4	---
  phy0	5GHz	*:d5	---

Installation:

  2 ways to flash factory.bin from OEM:

  - if you get Failsafe Mode from failed flash:
      only use it to flash Original firmware from Engenius
      or risk kernel loop or halt which requires serial cable

  Method 1: Firmware upgrade page:

    OEM webpage at 192.168.1.1
    username and password "admin"
    Navigate to "Firmware" page from left pane
    Click Browse and select the factory.bin image
    Upload and verify checksum
    Click Continue to confirm and wait 3 minutes

  Method 2: Serial to load Failsafe webpage:

    After connecting to serial console and rebooting...
    Interrupt uboot with any key pressed rapidly
    execute `run failsafe_boot` OR `bootm 0x9fd70000`
    wait a minute
    connect to ethernet and navigate to
    "192.168.1.1/index.htm"
    Select the factory.bin image and upload
    wait about 3 minutes

Return to OEM:

  If you have a serial cable, see Serial Failsafe instructions
  otherwise, uboot-env can be used to make uboot load the failsafe image

  *DISCLAIMER*
  The Failsafe image is unique to Engenius boards.
  If the failsafe image is missing or damaged this will not work
  DO NOT downgrade to ar71xx this way, it can cause kernel loop or halt

  ssh into openwrt and run
  `fw_setenv rootfs_checksum 0`
  reboot, wait 3 minutes
  connect to ethernet and navigate to 192.168.1.1/index.htm
  select OEM firmware image from Engenius and click upgrade

TFTP recovery:

  rename initramfs to 'vmlinux-art-ramdisk'
  make available on TFTP server at 192.168.1.101
  power board
  hold or press reset button repeatedly

  NOTE: for some Engenius boards TFTP is not reliable
  try setting MTU to 600 and try many times

Format of OEM firmware image:

  The OEM software of EnStationAC is a heavily modified version
  of Openwrt Altitude Adjustment 12.09. One of the many modifications
  is to the sysupgrade program. Image verification is performed
  simply by the successful ungzip and untar of the supplied file
  and name check and header verification of the resulting contents.
  To form a factory.bin that is accepted by OEM Openwrt build,
  the kernel and rootfs must have specific names...

    openwrt-ar71xx-enstationac-uImage-lzma.bin
    openwrt-ar71xx-enstationac-root.squashfs

  and begin with the respective headers (uImage, squashfs).
  Then the files must be tarballed and gzipped.
  The resulting binary is actually a tar.gz file in disguise.
  This can be verified by using binwalk on the OEM firmware images,
  ungzipping then untaring.

  Newer EnGenius software requires more checks but their script
  includes a way to skip them, otherwise the tar must include
  a text file with the version and md5sums in a deprecated format.

  The OEM upgrade script is at /etc/fwupgrade.sh.

  OKLI kernel loader is required because the OEM software
  expects the kernel to be no greater than 1536k
  and the factory.bin upgrade procedure would otherwise
  overwrite part of the kernel when writing rootfs.

Note on PLL-data cells:

  The default PLL register values will not work
  because of the external AR8033 switch between
  the SOC and the ethernet PHY chips.

  For QCA955x series, the PLL registers for eth0 and eth1
  can be see in the DTSI as 0x28 and 0x48 respectively.
  Therefore the PLL registers can be read from uboot
  for each link speed after attempting tftpboot
  or another network action using that link speed
  with `md 0x18050028 1` and `md 0x18050048 1`.

  For eth0 at 1000 speed, the value returned was
  ae000000 but that didn't work, so following
  the logical pattern from the rest of the values,
  the guessed value of a3000000 works better.

  later discovered that delay can be placed on the PHY end only
  with phy-mode as 'rgmii-id' and set register to 0x82...

Tested from master, all link speeds functional

**Serial Access:**

  the RX line on the board for UART is shorted to ground by resistor R176
  therefore it must be removed to use the console
  but it is not necessary to remove to view boot log
  optionally, R175 can be replaced with a solder bridge short

  the resistors R175 and R176 are next to the UART pinout at JP1

**Return to OEM:**

  If you have a serial cable, see Serial Failsafe instructions

  Unlike most Engenius boards, this does not have a 'failsafe' image
  the only way to return to OEM is TFTP or serial access to u-boot

**TFTP recovery:**

  Unlike most Engenius boards, TFTP is reliable here

  rename initramfs-kernel.bin to 'ap.bin'
  make the file available on a TFTP server at 192.168.1.10
  power board while holding or pressing reset button repeatedly

  or with serial access:
  run `tftpboot` or `run factory_boot` with initramfs-kernel.bin
  then `bootm` with the load address

**Format of OEM firmware image:**

  The OEM software of ECB1200 is a heavily modified version
  of Openwrt Altitude Adjustment 12.09.

  This Engenius board, like ECB1750, uses a proprietary header
  with a unique Product ID. The header for factory.bin is
  generated by the mksenaofw program included in openwrt.

**Note on PLL-data cells:**

Tested on the EAP245 v1 running the latest firmware (v1.4.0). The binary
patch might not apply to uclited from other firmware versions.

EAP245 v1 device support was originally developed and maintained by
Julien Dusser out-of-tree. This patch and "ath79: prepare for 1-port
TP-Link EAP2x5 devices" are based on that work.

Flashing procedure is identical to other ubnt devices.
https://openwrt.org/toh/ubiquiti/common

Flashing through factory firmware
1. Ensure firmware version v8.7.0 is installed.
   Up/downgrade to this exact version.
2. Patch fwupdate.real binary using
   `hexdump -Cv /bin/ubntbox | sed 's/14 40 fe 27/00 00 00 00/g' | \
    hexdump -R > /tmp/fwupdate.real`
3. Make the patched fwupdate.real binary executable using
   `chmod +x /tmp/fwupdate.real`
4. Copy the squashfs factory image to /tmp on the device
5. Flash OpenWrt using `/tmp/fwupdate.real -m <squashfs-factory image>`
6. Wait for the device to reboot
(copied from Ubiquiti NanoBeam AC and modified)

To keep it consistent, we will add the gen1 variant to
the nanobeam ac gen1.

4d36569b9c ath79: fix ath10k caldata extraction on some D-Link DIR-842 C3 devices
According to forum threads [0][1] and a report on IRC by Doc-Saintly
some of those boards have calibration data in a different place. Only
one alternative location is known.

Without proper board calibration data (board.bin having all 0xff bytes)
ath10k firmware still tries to load but crashes on startup with a
confusing error message.

If you're applying this patch manually on your device do not forget to
remove /lib/firmware/ath10k/pre-cal-pci-0000:00:00.0.bin and reboot to
force caldata re-extraction.

This adds support for the TP-Link TL-WPA8630P (EU) in its v2.1
version. The only unique aspect for the firmware compared to v2
layout is the partition layout.

Note that while the EU version has different partitioning for
v2.0 and v2.1, the v2.1 (AU) is supported by the v2-int image.

If you plan to use this device, make sure you have a look at
the Wiki page to check whether the device is supported and
which image needs to be taken.

  - QCA9563 750MHz, 2.4GHz WiFi
  - QCA9888 5GHz WiFi
  - 8MiB SPI Flash
  - 128MiB RAM
  - 3 GBit Ports (QCA8337)
  - PLC (QCA7550)

Installation
------------

Installation is possible from the OEM web interface. Make sure to
install the latest OEM firmware first, so that the PLC firmware is
at the latest version. However, please also check the Wiki page
for hints according to altered partitioning between OEM firmware
revisions.

Notes
-----

The OEM firmware has 0x620000 to 0x680000 unassigned, so we leave
this empty as well. It is complicated enough already ...

a99614a44f ath79: consistently use "info" label for default-mac partition
The tp-link safeloader devices typically contain a partition
"default-mac" which stores the MAC addresses. It is followed by other
partitions containing device info, like

  {"default-mac", 0x610000, 0x00020},
  {"pin", 0x610100, 0x00020},
  {"product-info", 0x611100, 0x01000},

In DTS, we typically assign a 0x10000 sized partition for these,
which is mostly labelled "mac" or "info". In rarer cases, the
partitions have been enclosed in a larger "tplink" or "config"
partition.

However, when comparing different devices, the implementation appears
relatively arbitrary at the moment.
Thus, this PR aims at harmonizing these partitions by always using
the name "info" for the DTS partition containing "default-mac".
"info" is preferred over "mac" as we never just have "default-mac"
alone, but always some other device-info partitions as well.

While at it, this also establishes a similar partitioning for the
few devices where the "info" partitions are part of a bigger
unspecific "config" partition or similar.

Besides the harmonization itself, this also allows to merge a few
cases in 11-ath10k-caldata.

TP-Link EAP245 v3 is an AC1750 (802.11ac Wave-2) ceiling mount access
point. UART access (for debricking) requires non-trivial soldering.

Specifications:
* SoC: QCA9563 (CPU/DDR/AHB @ 775/650/258 MHz)
* RAM: 128MiB
* Flash: 16MiB SPI-NOR
* Wireless 2.4GHz (SoC): b/g/n 3x3

* Ethernet (QCA8337N switch): 2× 1GbE, ETH1 (802.3at PoE) and ETH2
* Green and amber status LEDs
* Reset switch (GPIO, available for failsafe)

Flashing instructions:
All recent firmware versions (latest is 2.20.0), can disable firmware
signature verification and use a padded firmware file to flash OpenWrt:
* ssh into target device and run `cliclientd stopcs`
* upload factory image via web interface

The stopcs-method is supported from firmware version 2.3.0. Earlier
versions need to be upgraded to a newer stock version before flashing
OpenWrt.

Factory images for these devices are RSA signed by TP-Link. While the
signature verification can be disabled, the factory image still needs to
have a (fake) 1024 bit signature added to pass file checks.

Debricking instructions:
You can recover using u-boot via the serial port:
* Serial port is available from J3 (1:TX, 2:RX, 3:GND, 4:3.3V)
* Bridge R237 to connect RX, located next to J3
* Bridge R225 to connect TX, located inside can on back-side of board
* Serial port is 115200 baud, 8n1, interrupt u-boot by holding ctrl+B
* Upload initramfs with tftp and upgrade via OpenWrt

Device mac addresses:
Stock firmware has the same mac address for 2.4GHz wireless and
ethernet, 5GHz is incremented by one. The base mac address is stored in
the 'default-mac' partition (offset 0x90000) at an offset of 8 bytes.
ART blobs contain no mac addresses.

22caf30a65 ath79: add support for Senao Engenius ENH202 v1
FCC ID: U2M-ENH200

Engenius ENH202 is an outdoor wireless access point with 2 10/100 ports,
built-in ethernet switch, internal antenna plates and proprietery PoE.

Specification:

  - Qualcomm/Atheros AR7240 rev 2
  - 40 MHz reference clock
  - 8 MB FLASH                  ST25P64V6P (aka ST M25P64)
  - 32 MB RAM
  - UART at J3                  (populated)
  - 2x 10/100 Mbps Ethernet     (built-in switch at gmac1)
  - 2.4 GHz, 2x2, 29dBm         (Atheros AR9280 rev 2)
  - internal antenna plates     (10 dbi, semi-directional)
  - 5 LEDs, 1 button            (LAN, WAN, RSSI) (Reset)

Known Issues:

  - Sysupgrade from ar71xx no longer possible
  - Power LED not controllable, or unknown gpio

MAC addresses:

  eth0/eth1  *:11   art 0x0/0x6
  wlan       *:10   art 0x120c

  The device label lists both addresses, WLAN MAC and ETH MAC,
  in that order.

  Since 0x0 and 0x6 have the same content, it cannot be
  determined which is eth0 and eth1, so we chose 0x0 for both.

Installation:

  2 ways to flash factory.bin from OEM:

  - Connect ethernet directly to board (the non POE port)
      this is LAN for all images
  - if you get Failsafe Mode from failed flash:
      only use it to flash Original firmware from Engenius
      or risk kernel loop or halt which requires serial cable

  Method 1: Firmware upgrade page:

    OEM webpage at 192.168.1.1
    username and password "admin"
    In upper right select Reset
    "Restore to factory default settings"
    Wait for reboot and login again
    Navigate to "Firmware Upgrade" page from left pane
    Click Browse and select the factory.bin image
    Upload and verify checksum
    Click Continue to confirm and wait 3 minutes

  Method 2: Serial to load Failsafe webpage:

    After connecting to serial console and rebooting...
    Interrupt boot with any key pressed rapidly
    execute `run failsafe_boot` OR `bootm 0x9f670000`
    wait a minute
    connect to ethernet and navigate to
    "192.168.1.1/index.htm"
    Select the factory.bin image and upload
    wait about 3 minutes

Return to OEM:

  If you have a serial cable, see Serial Failsafe instructions

  *DISCLAIMER*
  The Failsafe image is unique to Engenius boards.
  If the failsafe image is missing or damaged this will not work
  DO NOT downgrade to ar71xx this way, can cause kernel loop or halt

  The easiest way to return to the OEM software is the Failsafe image
  If you dont have a serial cable, you can ssh into openwrt and run

  `mtd -r erase fakeroot`

  Wait 3 minutes
  connect to ethernet and navigate to 192.168.1.1/index.htm
  select OEM firmware image from Engenius and click upgrade

Format of OEM firmware image:

  The OEM software of ENH202 is a heavily modified version
  of Openwrt Kamikaze bleeding-edge. One of the many modifications
  is to the sysupgrade program. Image verification is performed
  simply by the successful ungzip and untar of the supplied file
  and name check and header verification of the resulting contents.
  To form a factory.bin that is accepted by OEM Openwrt build,
  the kernel and rootfs must have specific names...

    openwrt-senao-enh202-uImage-lzma.bin
    openwrt-senao-enh202-root.squashfs

  and begin with the respective headers (uImage, squashfs).
  Then the files must be tarballed and gzipped.
  The resulting binary is actually a tar.gz file in disguise.
  This can be verified by using binwalk on the OEM firmware images,
  ungzipping then untaring, and by swapping headers to see
  what the OEM upgrade utility accepts and rejects.

  OKLI kernel loader is required because the OEM firmware
  expects the kernel to be no greater than 1024k
  and the factory.bin upgrade procedure would otherwise
  overwrite part of the kernel when writing rootfs.

Note on built-in switch:

  ENH202 is originally configured to be an access point,
  but with two ethernet ports, both WAN and LAN is possible.

  the POE port is gmac0 which is preferred to be
  the port for WAN because it gives link status

af9dee336d ath79: add support for Meraki MR16
Port device support for Meraki MR16 from the ar71xx target to ath79.

Specifications:

  * AR7161 CPU, 16 MiB Flash, 64 MiB RAM
  * One PoE-capable Gigabit Ethernet Port
  * AR9220 / AR9223 (2x2 11an / 11n) WLAN

Installation:

  * Requires TFTP server at 192.168.1.101, w/ initramfs & sysupgrade .bins
  * Open shell case and connect a USB to TTL cable to upper serial headers
  * Power on the router; connect to U-boot over 115200-baud connection
  * Interrupt U-boot process to boot Openwrt by running:
       setenv bootcmd bootm 0xbf0a0000; saveenv;
       tftpboot 0c00000 <filename-of-initramfs-kernel>.bin;
       bootm 0c00000;
  * Copy sysupgrade image to /tmp on MR16
  * sysupgrade /tmp/<filename-of-sysupgrade>.bin

Notes:

  - There are two separate ARTs in the partition (offset 0x1000/0x5000 and
    0x11000/0x15000) in the OEM device. I suspect this is an OEM artifact;
    possibly used to configure the radios for different regions,
    circumstances or RF frontends. Since the ar71xx target uses the
    second offsets, use that second set (0x11000 and 0x15000) for the ART.

  - kmod-owl-loader is still required to load the ART partition into the
    driver.

  - The manner of storing MAC addresses is updated from ar71xx; it is
    at 0x66 of the 'config' partition, where it was discovered that the
    OEM firmware stores it. This is set as read-only. If you are
    migrating from ar71xx and used the method mentioned above to
    upgrade, use kmod-mtd-rw or UCI to add the MAC back in. One more
    method for doing this is described below.

  - Migrating directly from ar71xx has not been thoroughly tested, but
    one method has been used a couple of times with good success,
    migrating 18.06.2 to a full image produced as of this commit. Please
    note that these instructions are only for experienced users, and/or
    those still able to open their device up to flash it via the serial
    headers should anything go wrong.

    1) Install kmod-mtd-rw and uboot-envtools
    2) Run `insmod mtd-rw.ko i_want_a_brick=1`
    3) Modify /etc/fw_env.config to point to the u-boot-env partition.
       The file /etc/fw_env.config should contain:

       # MTD device   env offset  env size    sector size
       /dev/mtd1      0x00000     0x10000     0x10000

       See https://openwrt.org/docs/techref/bootloader/uboot.config
       for more details.

    4) Run `fw_printenv` to verify everything is correct, as per the
       link above.
    5) Run `fw_setenv bootcmd bootm 0xbf0a0000` to set a new boot address.
    6) Manually modify /lib/upgrade/common.sh's get_image function:
       Change ...

       cat "$from" 2>/dev/null | $cmd

       ... into ...

       (
         dd if=/dev/zero bs=1 count=$((0x66)) ; # Pad the first 102 bytes
         echo -ne '\x00\x18\x0a\x12\x34\x56'  ; # Add in MAC address
         dd if=/dev/zero bs=1 count=$((0x20000-0x66-0x6)) ; # Pad the rest
         cat "$from" 2>/dev/null | $cmd
       )

       ... which, during the upgrade process, will pad the image by
       128K of zeroes-plus-MAC-address, in order for the ar71xx's
       firmware partition -- which starts at 0xbf080000 -- to be
       instead aligned with the ath79 firmware partition, which
       starts 128K later at 0xbf0a0000.

    7) Copy the sysupgrade image into /tmp, as above
    8) Run `sysupgrade -F /tmp/<sysupgrade>.bin`, then wait

    Again, this may BRICK YOUR DEVICE, so make *sure* to have your
    serial cable handy.

Addenda:

  - The MR12 should be able to be migrated in a nearly identical manner as
    it shares much of its hardware with the MR16.

  - Thank-you Chris B for copious help with this port.

Specification
SoC: Qualcomm Atheros QCA9558
RAM: 128 MB DDR2
Flash: 16 MB SPI NOR
WIFI: 2.4 GHz 3T3R integrated
      5 GHz 3T3R QCA9880 Mini PCIe card
Ethernet: 1x 10/100/1000 Mbps AR8035-A, PoE capable (802.3at)
LEDS: 5x, which four are GPIO controlled
Buttons: 1x GPIO controlled
UART: 4 pin header near Mini PCIe card, starting count from white
      triangle on PCB
      1. VCC 3.3V, 2. GND, 3. TX, 4. RX
      baud: 115200, parity: none, flow control: none

MAC addresses
Calibration data does not contain valid MAC addresses.
The calculated MAC addresses are chosen in accordance with OEM firmware.

Because of:
a) constrained environment (SNMP) when connecting through Telnet
   or SSH,
b) hard-coded kernel and rootfs sizes,
c) checksum verification of kerenel and rootfs images in bootloder,

creating factory image accepted by OEM web interface is difficult,
therefore, to install OpenWrt on this device UART connection is needed.
The teardown is simple, unscrew four screws to disassemble the casing,
plus two screws to separate mainboard from the casing.
Before flashing, be sure to have a copy of factory firmware, in case You
wish to revert to original firmware.

Installation
1. Prepare TFTP server with OpenWrt initramfs-kernel image.
2. Connect to LAN port.
3. Connect to UART port.
4. Power on the device and when prompted to stop autoboot, hit any key.
5. Alter U-Boot environment with following commands:
    setenv failsafe_boot bootm 0x9f0a0000
    saveenv
6. Adjust "ipaddr" and "serverip" addresses in U-Boot environment, use
   'setenv' to do that, then run following commands:
    tftpboot 0x81000000 <openwrt_initramfs-kernel_image_name>
    bootm 0x81000000
7. Wait about 1 minute for OpenWrt to boot.
8. Transfer OpenWrt sysupgrade image to /tmp directory and flash it
   with:
    sysupgrade -n /tmp/<openwrt_sysupgrade_image_name>
9. After flashing, the access point will reboot to OpenWrt. Wait few
   minutes, until the Power LED stops blinking, then it's ready for
   configuration.
