fe197b8b09 ramips: mt7621: disable images for gehua_ghl-r-001
This device OOPs during the boot due to broken flash. It can be probably
fixed with `broken-flash-reset` once ramips is on 4.19 kernel.

So disable images for this device until its fixed.

a3ffeb413b ramips: Fix sysupgrade for Xiaomi mir3g
This mostly reverts the original commit e9929ebeea ("ramips: Fix
sysupgrade for Xiaomi mir3g") and replaces it with setting the
BOARD_NAME to the old value.

This way the folder in the tar will be named sysupgrade-mir3g and not
sysupgrade-xiaomi_mir3g and the sysupgrade in OpenWrt 18.06 can find it.

Without this change sysupgrade from 18.06 to 19.07 is only possible with
the -F option.

I tested the following sysupgrades successfully without -F
18.06 -> 19.07
19.07 -> master
master -> 19.07

Without this change sysupgrade from 18.06 to 19.07 is only possible with
the -F option.
In OpenWrt 18.06 the nand_do_platform_check() function is called with
the board name mir3g only, if the tar does not use mir3g it will fail.
OpenWrt 19.07 and later support the metadata with the supported_devices
attribute to allow renaming. Do the renaming of the target between 19.07
and master like it is done for some other boards.

I tested the following sysupgrades successfully without -F
18.06 -> 19.07

52c9f95178 ramips: allow JCG_MAXSIZE in kiB in Build/jcg-header
This allows JCG_MAXSIZE to be specified in kilobytes. This makes
this value more consistent and easier comparable with other size
variables.

This also changes the only occurence of the variable, for Cudy WR1000.

This is backported to 19.07 for convenience, as other developers
backporting device support might not be aware that JCG_MAXSIZE in
kilobytes would not work there.

71469caa0a ramips: add support for ALFA Network Quad-E4G
ALFA Network Quad-E4G is a universal Wi-Fi/4G platform, which offers
three miniPCIe (PCIe, USB 2.0, SIM) and a single M.2 B-key (dual-SIM,
USB 3.0) slots, RTC and five Gigabit Ethernet ports with PoE support.

Specification:

- MT7621A (880 MHz)
- 256/512 MB of RAM (DDR3)
- 16/32+ MB of FLASH (SPI NOR)
- optional second SPI flash (8-pin WSON/SOIC)
- 1x microSD (SDXC) flash card reader
- 5x 10/100/1000 Mbps Ethernet, with passive PoE support (24 V) in LAN1
- optional 802.3at/af PoE module for WAN
- 3x miniPCIe slot (with PCIe and USB 2.0 buses, micro SIM and 5 V)
- 1x M.2/NGFF B-key 3042 (USB 3.0/2.0, mini + micro SIM)
- RTC (TI BQ32002, I2C bus) with backup battery (CR2032)
- external hardware watchdog (EM Microelectronic EM6324)
- 1x USB 2.0 Type-A
- 1x micro USB Type-B for system serial console (Holtek HT42B534)
- 11x LED (5 for Ethernet, 5 driven by GPIO, 1x power indicator)
- 3x button (reset, user1, user2)
- 1x I2C (4-pin, 2.54 mm pitch) header on PCB
- 4x SIM (6-pin, 2.00 mm pitch) headers on PCB
- 2x UART2/3 (4-pin, 2.54 mm pitch) headers on PCB
- 1x mechanical power switch
- 1x DC jack with lock (24 V)

Other:

- U-Boot selects default SIM slot, based on value of 'default_sim' env
  variable: '1' or unset -> SIM1 (mini), '2' -> SIM2 (micro). This board
  has additional logic circuit for M.2 SIM switching. The 'sim-select'
  will work only if both SIM slots are occupied. Otherwise, always slot
  with SIM inside is selected, no matter 'sim-select' value.
- U-Boot enables power in all three miniPCIe and M.2 slots before
  loading the kernel
- this board supports 'dual image' feature (controlled by 'dual_image'
  U-Boot environment variable)
- all three miniPCIe slots have additional 5 V supply on pins 47 and 49
- the board allows to install up to two oversized miniPCIe cards (vendor
  has dedicated MediaTek MT7615N/D cards for this board)
- this board has additional logic circuit controlling PERSTn pins inside
  miniPCIe slots. By default, PERSTn (GPIO19) is routed to all miniPCIe
  slots but setting GPIO22 to high allows PERSTn control per slot, using
  GPIO23-25 (value is inverted)

Flash instructions:

You can use the 'sysupgrade' image directly in vendor firmware which is
based on OpenWrt (make sure to not preserve settings - use 'sysupgrade
-n -F ...' command). Alternatively, use web recovery mode in U-Boot:

1. Power the device with reset button pressed, the modem LED will start
   blinking slowly and after ~3 seconds, when it starts blinking faster,
   you can release the button.
2. Setup static IP 192.168.1.2/24 on your PC.
3. Go to 192.168.1.1 in browser and upload 'sysupgrade' image.

c515cd7c34 ramips: add support for ALFA Network R36M-E4G
ALFA Network R36M-E4G is a dual-SIM, N300 Wi-Fi, compact size platform
based on MediaTek MT7620A WiSoC. This product is designed for operation
with 4G modem (can be bought in bundle with Quectel EC25, EG25 or EP06)
but supports also Wi-Fi modules (miniPCIe slot has USB and PCIe buses).

Specification:

- MT7620A (580 MHz)
- 64/128/256 MB of RAM (DDR2)
- 16/32+ MB of FLASH (SPI NOR)
- 2x 10/100 Mbps Ethernet, with passive PoE support (24 V)
- 2T2R 2.4 GHz (MT7620A), with ext. LNA (RFFM4227)
- 1x miniPCIe slot (with PCIe and USB 2.0 buses and optional 5 V)
- 2x SIM slot (mini, micro) with detect and switch driven by GPIO
- 2x u.fl antenna connectors (for Wi-Fi)
- 8x LED (7 driven by GPIO)
- 2x button (reset, wifi)
- 2x UART (4-pin/2.54 mm pitch, 10-pin/1.27 mm pitch) headers on PCB
- 1x I2C (4-pin, 1.27 mm pitch) header on PCB
- 1x LED (8-pin, 1.27 mm pitch) header on PCB
- 1x DC jack with lock (12 V)

Other:

- there is a dedicated, 4-pin connector for optional RTC module (Holtek
  HT138x) with 'enable' input, not available at the time of preparing
  support for this board
- miniPCIe slot supports additional 5 V supply on pins 47 and 49 but a
  jumper resistor (R174) is not installed by default
- U-Boot selects default SIM slot, based on value of 'default_sim' env
  variable: '1' or unset -> SIM1 (mini), '2' -> SIM2 (micro). This will
  work only if both slots are occupied, otherwise U-Boot will always
  select slot with SIM card inside (user can override it later, in
  user-space)
- U-Boot resets the modem, using PERSTn signal, before starting kernel
- this board supports 'dual image' feature (controlled by 'dual_image'
  U-Boot environment variable)

Flash instruction:

You can use the 'sysupgrade' image directly in vendor firmware which is
based on OpenWrt (make sure to not preserve settings - use 'sysupgrade
-n -F ...' command). Alternatively, use web recovery mode in U-Boot:

1. Power the device with reset button pressed, the modem LED will start

Upstream kernel added support for RAW_APPENDED_DTB on ralink arch
in the following commit:
02564fc89d3d ("ralink: Introduce fw_passed_dtb to arch/mips/ralink")

Use upstream solution and get rid of our OWRTDTB hack.
This commit set DEVICE_DTS to $$(DTS) instead of replacing DTS with
DEVICE_DTS in device profile because DTS variable will be dropped
in later commits.

Flash instruction:
U-boot has a builtin web recovery page:
1. Hold the reset button while powering it up
2. Connect to the ethernet and set an IP in 192.168.1.0/24 range
3. Open your browser and upload firmware through http://192.168.1.1

Note about the LTE modem:
If your router comes with an EC25 module and it doesn't show up
as a QMI device, you should do the following to switch it to QMI
mode:
1. Install kmod-usb-serial-option and a terminal software
   (e.g. minicom or screen). All 4 serial ports of the modem
   should be available now.
2. Open /dev/ttyUSB3 with the terminal software and type this
   AT command: AT+QCFG="usbnet",0
3. Power-cycle the router. You should now get a QMI device
   recognized.

  WR1000_US_92.122.2.4987.201806261609.bin
If in the future these firmwares will not be available anymore,
you have to find the new XOR key.

1) Download the original FW from the Cudy website.

   (For example WR1000_EU_92.122.2.4987.201806261618.bin)

2) Remove the header.

   dd if="WR1000_EU_92.122.2.4987.201806261618.bin" of="WR1000_EU_92.122.2.4987.201806261618.bin.mod" skip=8 bs=64

3) XOR the new file with the region key.

   FOR EU: 7B76741E67594351555042461D625F4545514B1B03050208000603020803000D
   FOR US: 7B76741E675943555D5442461D625F454555431F03050208000603060007010C

   You can use OpenWrt's tools/firmware-utils/src/xorimage.c tool for this:

   xorimage -i WR1000..bin.mod -o stock-firmware.bin -x -p 7B767..

   Or, you can use this tool (CHANGE THE XOR KEY ACCORDINGLY!):
   https://gchq.github.io/CyberChef/#recipe=XOR(%7B'option':'Hex','string':''%7D,'',false)

4) Check the resulting decrypted image.

   Check if bytes from 0x20 to 0x3f are:
   4C 69 6E 75 78 20 4B 65 72 6E 65 6C 20 49 6D 61 67 65 00 00 00 00 00 00 00 00 00 00 00 00 00 00

   Alternatively, you can use u-boot's tool dumpimage tool to check
   if the decryption was successful. It should look like:

   # dumpimage -l stock-firmware.bin
   Image Name:   Linux Kernel Image
   Created:      Tue Jun 26 10:24:54 2018
   Image Type:   MIPS Linux Kernel Image (lzma compressed)
   Data Size:    4406635 Bytes = 4303.35 KiB = 4.20 MiB
   Load Address: 80000000
   Entry Point:  8000c150

5) Flash it via forced firmware upgrade and don't "Keep Settings"

   CLI: sysupgrade -F -n stock-firmware.bin

   LuCI: make sure to click on the "Keep settings" checkbox
         to disable it. You'll need to do this !TWICE! because
         on the first try, LuCI will refuse the image and reset
	 the "Keep settings" to enable. However a new
         "Force upgrade" checkbox will appear as well.
         Make sure to do this very carefully!

869376710d ramips: Add support for ZBT WE826-E
ZBT WE826-E is a dual-SIM version of the ZBT WE826. The router has the
following specifications:

- MT7620A (580 MHz)
- 128MB RAM
- 32MB of flash (SPI NOR)
- 5x 10/100Mbps Ethernet (MT7620A built-in switch)
- 1x microSD slot
- 1x miniPCIe slot (only USB2.0 bus)
- 2x SIM card slots (standard size)
- 1x USB2.0 port
- 1x 2.4GHz wifi (rt2800)
- 10x LEDs (4 GPIO-controlled)
- 1x reset button

The following have been tested and working:
- Ethernet switch
- wifi
- miniPCIe slot
- USB port
- microSD slot
- sysupgrade
- reset button

Installation and recovery:

In order to install OpenWRT the first time or recover the router, you
can use the web-based recovery system. Keep the reset button pressed
during boot and access 192.168.1.1 in your browser when your machine
obtains an IP address.  Upload the firmware to start the recovery
process.

How to swap SIMs:

You control which SIM slot to use by writing 0/1 to
/sys/class/gpio/gpio13/value. In order for the change to take effect,
you can either use AT-commands (AT+CFUN) or power-cycle the modem (write
0/1 to /sys/class/gpio/gpio14/value).

52b59a984f ramips: Add support for Head Weblink HDRM200
Head Weblink HDRM200 is a dual-sim router based on MT7620A. The detailed
specifications are:

- MT7620A (580MHz)
- 64MB RAM
- 16MB of flash (SPI NOR)
- 6x 10/100Mbps Ethernet (MT7620A built-in switch)
- 1x microSD slot
- 1x miniPCIe slot (only USB2.0 bus). Device is shipped with a SIMCOM
SIM7100E LTE modem.
- 2x SIM slots (standard size)
- 1x USB2.0 port
- 1x 2.4GHz wifi (rt2800)
- 1x 5GHz wifi (mt7612)
- 1x reset button
- 1x WPS button
- 3x GPIO-controllable LEDs
- 1x 10 pin terminal block (RS232, RS485, 4 x GPIO)

Tested:
- Ethernet switch
- Wifi
- USB slot
- SD card slot
- miniPCIe-slot
- sysupgrade
- reset button

Installation instructions:

Installing OpenWRT for the first time requires a bit of work, as the
board does not ship with OpenWRT. In addition, the bootloader
automatically reboots when installing an image over tftp. In order to
install OpenWRT on the HDRM200, you need to do the following:

* Copy the initramfs-image to your tftp-root (default filename is
test.bin) and configure networking accordingly (default server IP is
10.10.10.3, client 10.10.10.123). Start your tftp server.
* Open the board and connect to UART. The pins are exposed and clearly
marked.
* Boot the board and press 1.
* Either use the default filename and client/server IP-addresses, or
specify your own.

The image should now be loaded to memory and board boot. If the router
reboots while the image is loading, you need to try again. Once the
board has booted, copy the sysupgrade-image to the router and run
sysupgrade in order to install OpenWRT to the flash.

Notes:

- You control which SIM slot to use by writing 0/1 to
/sys/class/gpio/gpio0/value. In order for the change to take
effect, you can either use AT-commands (AT+CFUN) or power-cycle the
modem (write 0/1 to /sys/class/gpio/gpio21/value).
- RS485 is available on /dev/ttyS0.
- RS232 is available on /dev/ttyS1.
- The name of the ioX-gpios map to the labels on the casing.

FLASH: 256MB NAND
WiFi:  2.4GHz 4x4 MT7615 b/g/n (Needs driver, See Issues!)

LED:   Power/Status
BTN:   RESET
UART:  115200 8n1

Partition layout and boot:

Stock Xiaomi firmware has the MTD split into (among others)

- kernel0 (@0x200000)
- kernel1 (@0x600000)
- rootfs0
- rootfs1
- overlay (ubi)

Xiaomi uboot expects to find kernels at 0x200000 & 0x600000
referred to as system 1 & system 2 respectively.
a kernel is considered suitable for handing control over
if its linux magic number exists & uImage CRC are correct.
If either of those conditions fail, a matching sys'n'_fail flag
is set in uboot env & a restart performed in the hope that the
alternate kernel is okay.
If neither kernel checksums ok and both are marked failed, system 2
is booted anyway.

Note uboot's tftp flash install writes the transferred
image to both kernel partitions.

Installation:

Similar to the Xiaomi MIR3G, we keep stock Xiaomi firmware in
kernel0 for ease of recovery, and install OpenWRT into kernel1 and
after.

The installation file for OpenWRT is a *squashfs-factory.bin file that
contains the kernel and a ubi partition. This is flashed as follows:

nvram set flag_try_sys1_failed=1
nvram set flag_try_sys2_failed=0
nvram commit
dd if=factory.bin bs=1M count=4 | mtd write - kernel1
dd if=factory.bin bs=1M skip=4 | mtd write - rootfs0
reboot

Reverting to stock:

The part of stock firmware we've kept in kernel0 allows us to run stock
recovery, which will re-flash stock firmware from a *.bin file on a USB.

For this we do the following:

fw_setenv flag_try_sys1_failed 0
fw_setenv flag_try_sys2_failed 1
reboot

After reboot the LED status light will blink red, at which point pressing
the 'reset' button will cause stock firmware to be installed from USB.

Issues:

OpenWRT currently does not have support for the MT7615 wifi chips. There is
ongoing work to add mt7615 support to the open source mt76 driver. Until that
support is in place, there are closed-source kernel modules that can be used.

9b6413982c ramips: add support for ALFA Network Tube-E4G
ALFA Network Tube-E4G is an outdoor, dual-SIM LTE Cat. 4 CPE, based on
MediaTek MT7620A, equipped with Quectel EC25 miniPCIe modem.

Specification:

- MT7620A (580 MHz)
- 64/128/256 MB of RAM (DDR2)
- 16/32 MB of flash (SPI NOR)
- 1x 10/100 Mbps Ethernet, with passive PoE support (24 V)
- 1x miniPCIe slot (with PCIe and USB 2.0 buses)
- 2x SIM slot (mini, micro) with detect and switch driven by GPIO
- 1x detachable antenna (modem main)
- 1x internal antenna (modem div)
- 1x GPS passive antenna (optional)
- 5x LED (all driven by GPIO)
- 1x button (reset)
- UART (4-pin, 2.54 mm pitch) header on PCB

Other:

Default SIM slot is selected at an early stage by U-Boot, based on
'default_sim' environment value: 1 or unset = SIM1 (mini), 2 = SIM2
(micro). U-Boot also resets the modem, using #PERST signal, before
starting kernel.

Flash instruction:

You can use the 'sysupgrade' image directly in vendor firmware which is
based on OpenWrt (make sure to not preserve settings - use 'sysupgrade
-n -F ...' command). Alternatively, use web recovery mode in U-Boot:

1. Power the device with reset button pressed, the LAN LED will start
   blinking slowly and after ~3 seconds, when it starts blinking faster,
   you can release the button.
2. Setup static IP 192.168.1.2/24 on your PC.
3. Go to 192.168.1.1 in browser and upload 'sysupgrade' image.
