It isn't feasible to literally backport all upstream phylink_pcs changes
down to Linux 5.15: It's just too many patches, and many downstream
drivers and hacks are likely to break. We are too close to branching off
to risk this, and it's also just too much work.
Instead just add helper functions used by modern PCS drivers while keeping
the original functions instact as well. While this may add a kilobyte or
two of extra kernel size, it has the advantage that we get the best of both
worlds: None of the existing codepaths are touched, but yet we have the
option to backport singular improvements to Ethernet drivers where needed.

One user reported that his SIMAX1800T couldn't boot like the others. After
debugging, I found that this was caused by the disabled PCIe port. I cannot
reproduce this issue on my SIMAX1800T. But when I disabled pcie2 on the
ASUS RT-AC57U, I got the same result.
It seems that disabling these unused PCIe ports on some mt7621 revisions
will cause PCIe to fail to initialize. So we'd better to re-enable them on
all related mt7621 devices.

0x000000fb0000-0x000001000000 : "Private"
```
The kernel partition will be replaced with the OpenWrt image, the other
partitions are left untouched.
"Config2" seems to be the config storage used by the stock firmware.
"Private" is a 320kB empty JFFS2 partition that comes with the stock
firmware. One can get a larger space for OpenWrt by merging it with
"Kernel".
OpenWrt flash layout:
```
0x000000000000-0x000000030000 : "u-boot"
0x000000030000-0x000000040000 : "u-boot-env"

0x000000fb0000-0x000001000000 : "private_stock"
```
The OpenWrt image must have 96 bytes of padding in the header.
MAC addresses on OEM firmware:
| | location on the flash | notes |
|------ |----------------------- |---------- |
| lan (eth2) | factory + 0xe000 | on label |
| wan (eth3) | factory + 0xe006 | |
| 2.4g (rax0) | not on flash | lan + 1 |
| 5g (ra0) | not on flash | lan + 2 |
Mac addresses of the 2.4g and 5g interface are stored as ASCII strings in
the u-boot-env partition, but they are not used. OpenWrt calculates
Wifi Mac addresses based on the LAN Mac.
Flash and test instructions:
Flash the encrypted image (available in the OpenWrt forum) through the
stock D-Dink web interface.
1. Open the case, and solder the 4-pin header near the WAN port.
2. Connect it to a USB-UART TTL (3.3V) adapter, no need to connect VCC.
3. Open a terminal emulator (e.g. `screen /dev/ttyUSB0` on linux) with
the settings mentioned above.
4. Setup a TFTP server on your PC that can serve
`xxx-ramips-mt7621-dlink_dir-853-a1-initramfs-kernel.bin`.
5. Connect any LAN port to your PC and set a static IPv4 address to
192.168.0.101 (netmask 255.255.255.0).
6. Power on the device and keeps pressing 1 until you see the prompt.
7. Use default IP addresses and enter the file name accordingly, then hit
enter.
8. Wait until it boots to OpenWrt, the default IP address is 192.168.1.1,
you need to change your PC network adapter to use DHCP in order to access
LUCI.
9. So far, the OpenWrt runs in RAM and the flash contents are not touched.
You can try OpenWrt without having to overwrite the stock firmware, a
reboot clears all changes.
10. Optionally, backup the stock firmware (the "firmware" partition) in
Luci.
11. To permantly install OpenWrt to the device , click
on "System -> Backup/Flash Firmware" in Luci and flash
`xxx-ramips-mt7621-dlink_dir-853-a1-squashfs-sysupgrade.bin`
Known problems:
* WLAN0 defaults to 5G after a fresh installation, to enable 2.4G network,
you need to config it manually in LUCI.
* If you see jffs2 related warnings/errors after updating from the stock
web interface, you need to do a reset in LUCI. The error will be gone after
a cold reboot.

Engenius EPG600 is an indoor wireless router with
1 Gb ethernet switch, dual-band wireless,
internal antenna plates, USB, and phone lines (not supported)
this board is a Senao device:
the hardware is equivalent to EnGenius ESR600 (except for phone lines)
the software is Senao SDK which is based on openwrt and uboot
which uses the legacy Senao header with Vendor / Product IDs
to verify the firmware upgrade image.
**Specification:**
- MT7620 SOC MIPS 24kec, 2.4 GHz WMAC, 2x2
- RT5592N WLAN PCI chip, 5 GHz, 2x2
- QCA8337N Gb SW RGMII GbE, SW P0 -- SOC P5, 5 LEDs
- 40 MHz clock
- 16 MB FLASH MX25L12845EMI-10G
- 64 MB RAM NT5TU32M16
- UART console J2, populated
- USB 2.0 port direct to SOC
- 6 GPIO LEDs power, 2G, 5G, wps2g, wps5g, line
- 3 buttons reset, wps, "reg" (registeration)
- 4 antennas internal omni-directional plates
NOT YET SUPPORTED: VoIP
- Si3050-FT + Si3019-FT Voice DAA, SPI control, PCM data
- Phone Ports "TEL", "LINE" RJ11, 4P2C (2 pins)
**MAC addresses:**
MAC address labeled as MAC ADDRESS
MACs present in both wifi cal data and uboot environment
eth0.1/phy1 ---- *:82 rf 0x4
phy0 ---- *:83 factory 0x4
eth0.2 MAC *:b8 "wanaddr"
**Installation:**
Method 1: Firmware upgrade page:
(if you cannot access the APs webpage)
factory reset with the reset button
connect ethernet to a computer
OEM webpage at 192.168.0.1
username and password 'admin'
Navigate to gear icon, "Device Management", "Tools"
select the factory.dlf image
Upload and verify checksum
Method 2: Serial to upload initramfs:
Follow directions for TFTP recovery
upload and boot initramfs and do a sysupgrade
**TFTP recovery:**
Requires UART serial console, reset button does nothing
rename initramfs-kernel.bin to 'uImageEPG600'
make available on TFTP server at 192.168.99.8
power board, interrupt boot with "4"
execute `tftpboot` and `bootm` (with the load address)
**Return to OEM:**
Images from OEM are provided, but not compatible
with openwrt sysupgrade. So it must be modified.
Alternatively, back up all mtd partitions before flashing
**Note on switch registers:**
The necessary registers needed for the QCA8337 switch
can be read from interrupted boot (tftpboot, bootm)
by using the following lines in the switch driver ar8327.c
in the function 'ar8327_hw_config_of'
where 'qca,ar8327-initvals' is parsed from DTS
before the new register values are written:
pr_info("0x04 %08x\n", ar8xxx_read(priv, AR8327_REG_PAD0_MODE));
pr_info("0x08 %08x\n", ar8xxx_read(priv, AR8327_REG_PAD5_MODE));
pr_info("0x0c %08x\n", ar8xxx_read(priv, AR8327_REG_PAD6_MODE));

in order for the option ephy-disable to work
without also needing ephy-base option,
we have to skip all the lines that write to mdio addresses that
assume those addresses do not have an external switch.
Otherwise, ephy ports will be disabled in hardware,
but register writes still happen as if they are enabled.
Split the functions so that other things are done first,
and ephy port setup can be skipped with a simple "return".

These devices have a partition table stored in flash, which compensates
for any pre-existing bad blocks by enlarging the respective partition.
This means that the current static partition table is only correct for
devices without any bad blocks.
Typical results of this mismatch are degraded wireless performance and
wrong MAC addresses, when the factory partition is shifted due to a bad
block somewhere before it. If there is a bad block already before the
ubi partition, then OpenWrt may not run at all because the kernel can't
find the rootfs.
Use the on-flash partition table to fix these issues. Replace the two
reserved partitions by the full partition list, as the driver does not
allow merging them.

5 GHz *:f9 factory 0x8000+0x4 (mtd-eeprom+0x4)
Installation:
Factory firmware is based on a custom OpenWrt 17.x.
Installation is the same as for Xiaomi Mi Router 4A Gigabit.
Probably the easiest way to install is to use the script from
this repository: https://github.com/acecilia/OpenWRTInvasion/pull/155
In a more advanced case, you can do everything yourself:
- gain access to the device through one of the exploits described
in the link above
- upload sysupgrade image to /tmp
- overwrite stock firmware:
# mtd -e OS1 -r write /tmp/sysupgrade.bin OS1
Recovery:
Recovery procedure is the same as for Xiaomi Mi Router 4A Gigabit.
Possible options can be found here:
https://openwrt.org/inbox/toh/xiaomi/xiaomi_mi_router_4a_gigabit_edition
One of the ways is to use another router with OpenWrt:
- connect both routers by their LAN ports
- download stock firmware from [1]
- place it inside /tmp/test.bin on the main router
- configure PXE/TFTP on the main router
- power off 4Av2, hold Reset button, power on
- as soon as image download via TFTP starts, Reset can be released

- drop unneeded default-state for led_power
- concat firmware partitions to extend available free space
- increase spi flash frequency to 32 Mhz (value from stock firmware bootlog)
- drop broken-flash-reset because of onboard flash chip W25Q256FV has reset support
- add compatible for pcie wifi according to kernel documetation
- switch to wan mac address with offset 0x28 in rf-eeprom

This is cosmetic change. The hex value is related to the device
model and more human friendly.

This device has two sets of volumes: main ones (`kernel`, `rootfs`, etc) and
'backup' (`kernel.b`, `rootfs.b`, etc). Bootloader tries to determine which set of
volumes to use by looking at contens of `extra-para` and `extra-para.b` volumes.
These volumes contain JSON that looks like this:
```
{
"dbootFlag": "1",
"integerFlag": "1",
"fwFlag": "GOOD",
"score":1
}
```
It looks like the bootloader looks for `"fwFlag": "GOOD"` (as opposed to `BAD`)
then it compares `score` field - whichever 'good' volume has bigger score wins.
This determines which set of volumes to use to boot.
So for example if `extra-para` is good and has bigger score then `kernel`,
`rootfs`, etc volumes are used. This means bootloader needs to explain to the
kernel which volume to use for the rootfs. After looking at bootloader code with
disassembler I think it contains a bug. Relevant part of code looks something
like this:
```
if (image_id == 0) {
rootfs_volume_id = 8;
rootfs_volume_name = "rootfs";
}
else {
rootfs_volume_id = 0xf;
rootfs_volume_name = "rootfs.b";
}
sprintf(
&buffer,
0x800,
"console=ttyS0,115200 noinitrd ubi.mtd=3,2048 ubi.block=0,%s
root=/dev/ubiblock0_%d DKMGT_IMAGE_ID=%d DKMGT_IMAGE_TYPE=ubi",
rootfs_volume_name,
rootfs_volume_id,
image_id
);
```
Where `image_id == 0` if 'normal' (not '*.b' set of volumes is used).
However from device dumps we know that from the factory `rootfs.b` has id 8 and
`rootfs` has id 15.
So from above we can see that ids and names of rootfs volumes do not match. More
over - they are hardcoded in the bootloader.
Both things are problematic for OpwnWRT which completely removes volumes on
update meaning that volume ids may actually change.
So instead of relying on bootloader to provide the kernel with root device this
patch forces kernel to determine root automatically - and it defaults to
`rootfs` volume which is correct for our purposes.
Overall this makes image boot fine from flash after sysupgrade from inirams.
assuming `extra-para*` volumes make bootloader use non-'*.b' set of volumes.

U-Boot: 1.1.3 (Dec 4 2017 - 11:37:57), Ralink 5.0.0.1
Serial
------
The serial port needs a TTL/RS-232 3V3 level converter! The Serial
setting is 57600-8-N-1. The board has an unpopulated 2.54mm straight pin
header.
The pinout is: VCC (the square), RX, TX, GND.
Installation
------------
See the Wiki page [1] for more details, it comes down to:
1. Open the device, take off the heat sink
2. Connect the SPI flash chip to a flasher, e.g. a Raspberry Pi. Also
connect the RESET pin for stability (thanks @FPSUsername for reporting)
3. Make a backup in case you want to revert to stock later
4. Flash the squashfs-factory.trx file to offset 0x50000 of the flash
5. Ensure the bootpartition variable is set to 0 in the U-Boot
environment located at 0x30000
Note that the U-Boot is password protected, this can optionally be
removed. See the forum [2] for more details.
MAC Addresses(stock)
--------------------
+----------+------------------+-------------------+
| use | address | example |
+----------+------------------+-------------------+
| Device | label | 00:00:00:11:00:00 |
| Ethernet | + 3 | 00:00:00:11:00:03 |
| 2g | + 0x020000f00001 | 02:00:00:01:00:01 |
| 5g | + 1 | 00:00:00:11:00:01 |
+----------+------------------+-------------------+
The label address is stored in ASCII in the board_data partition
Notes
-----
- This device has a dual-boot partition scheme, but OpenWRT will claim
both partitions for more storage space.
Known issues
------------
- 2g MAC address does not match stock due to missing support for that in
macaddr_add
- Only the power LED is configured by default

Reducing SPI flash frequency allows the build to boot on both old variants
with W25Q128 chip and new variants with XM25QH128C chip.
The old 80000000 value only boots on devices with the W25Q128 flash.
This is also the change Cudy themselves made in their openwrt builds and
their .dts file.
Removed m25p,fast-read as it is not needed with slower speeds.

Add support for D-Link DIR-1935 A1 based on similarities to DIR-882 A1,
DIR-867 A1 and other DIR-8xx A1 models. Existing DIR-882 A1 openwrt
"factory" firmware installs without modificaitons via the D-Link
Recovery GUI and has no known incompatibilities with the DIR-1935 A1.
Changes to be committed:
new file: target/linux/ramips/dts/mt7621_dlink_dir-1935-a1.dts
modified: target/linux/ramips/image/mt7621.mk
modified: target/linux/ramips/mt7621/base-files/etc/board.d/01_leds
Specifications:
* Board: Not known
* SoC: MediaTek MT7621 Family
* RAM: 128 MB (DDR3)
* Flash: 16 MB (SPI NOR)
* WiFi: MediaTek MT7615 Family (x2)
* Switch: 1 WAN, 4 LAN (Gigabit)
* Ports: 1 USB 3.0
* Buttons: Reset, WiFi Toggle, WPS
* LEDs: Power (green/orange), Internet (green/orange), WiFi 2.4G (green),
WiFi 5G (green)
Notes:
* 160MHz 5GHz is available in LuCi but does not appear to work (i.e. no
SSID is visible in wifi scanning apps on other devices) with either
official DIR-882 A1 firmware or a test build for the DIR-1935 A1 based
on the 22.03.2 branch. 80 MHz 5GHz works.
Serial port:
* Untested (potential user damage/error)
* Expected to be identical to other DIR-8xx A1 models:
* Parameters: 57600, 8N1
* Location: J1 header (close to the Reset, WiFi and WPS buttons)
* Pinout: 1 - VCC
2 - RXD
3 - TXD
4 - GND
Installation:
* D-Link Recovery GUI: power down the router, press and hold the reset
button, then re-plug it. Keep the reset button pressed until the power
LED starts flashing orange, manually assign a static IP address under
the 192.168.0.xxx subnet (e.g. 192.168.0.2) and go to http://192.168.0.1
* Some modern browsers may have problems flashing via the Recovery GUI,
if that occurs consider uploading the firmware through cURL:
curl -v -i -F "firmware=@file.bin" 192.168.0.1
