Flash instructions:
If your device comes with generic QSDK based firmware, you can login
over telnet (login: root, empty password, default IP: 192.168.188.253),
issue first (important!) 'fw_setenv' command and then perform regular
upgrade, using 'sysupgrade -n -F ...' (you can use 'wget' to download
image to the device, SSH server is not available):
fw_setenv bootcmd "bootm 0x9f050000 || bootm 0x9fe80000"
sysupgrade -n -F openwrt-...-yuncore_...-squashfs-sysupgrade.bin
In case your device runs firmware with YunCore custom GUI, you can use
U-Boot recovery mode:
1. Set a static IP 192.168.0.141/24 on PC and start TFTP server with
'tftp' image renamed to 'upgrade.bin'
2. Power the device with reset button pressed and release it after 5-7
seconds, recovery mode should start downloading image from server
(unfortunately, there is no visible indication that recovery got
enabled - in case of problems check TFTP server logs)

(backported from commit e5d4c09667)
YunCore QCA9k based devices released in 2019 require a custom TFTP image
for U-Boot built-in recovery mode (triggered with reset button). Image
has to be prepended with 'YUNCORE' keyword followed by U-Boot CLI
commands which will be executed later. Images without the custom header
will be ignored by U-Boot.
To be able to support both the vendor firmware (QSDK) and OpenWrt flash
layouts, used here commands change the 'bootcmd' before flashing image.
This commit adds generic helper script for YunCore devices with 16 MB of
flash and enables TFTP image generation for A770 model.

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

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.

New U-Boot version for MediaTek MT76x8/MT762x based ALFA Network boards
includes support for a 'dual image' feature. Users can enable it using
U-Boot environment variable 'dual_image' ('1' -> enabled).
When 'dual image' feature is enabled, U-Boot will modify DTB and divide
the original 'firmware' flash area into two, equal in size and aligned
to 64 KB partitions: 'firmware' and 'backup'. U-Boot will also adjust
size of 'firmware' area to match installed flash chip size.
U-Boot will load kernel from active partition which is marked with env
variable 'bootactive' ('1' -> first partition, '2' -> second partition)
and rename both partitions accordingly ('firmware' <-> 'backup').
There are 3 additional env variables used to control 'dual image' mode:
- bootlimit - maximum number of unsuccessful boot tries (default: '3')
- bootcount - current number of boot tries
- bootchanged - flag which informs that active partition was changed; if
it is set and 'bootcount' reaches 'bootlimit' value,
U-Boot will start web-based recovery which then updates
both partitions with provided image

Installation
------------
1. Grab the uboot for the Device from the 'u-boot-fritz1200'
subdirectory. Place it in the same directory as the 'eva_ramboot.py'
script. It is located in the 'scripts/flashing' subdirectory of the
OpenWRT tree.
2. Assign yourself the IP address 192.168.178.10/24. Connect your
Computer to one of the boxes LAN ports.
3. Connect Power to the Box. As soon as the LAN port of your computer
shows link, load the U-Boot to the box using following command.
> ./eva_ramboot.py --offset 0x85000000 192.168.178.1 uboot-fritz1200.bin
4. The U-Boot will now start. Now assign yourself the IP address
192.168.1.70/24. Copy the OpenWRT initramfs (!) image to a TFTP
server root directory and rename it to 'FRITZ1200.bin'.
5. The Box will now boot OpenWRT from RAM. This can take up to two
minutes.
6. Copy the U-Boot and the OpenWRT sysupgrade (!) image to the Box using
scp. SSH into the Box and first write the Bootloader to both previous
kernel partitions.
> mtd write /path/to/uboot-fritz1200.bin uboot0
> mtd write /path/to/uboot-fritz1200.bin uboot1
7. Remove the AVM filesystem partitions to make room for our kernel +
rootfs + overlayfs.
> ubirmvol /dev/ubi0 --name=avm_filesys_0
> ubirmvol /dev/ubi0 --name=avm_filesys_1
8. Flash OpenWRT peristently using sysupgrade.

TP-Link TL-WDR4900 v2 only has one combined WPS/Reset button, so

Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
(cherry picked from commit 25127f58b4)
In ar71xx there is only one combined mach file for Archer C5/C7 and
TL-WDR4900 v2. This one uses the same LED struct for all devices,
defining "green" LEDs for them. However, WDR4900 uses blue front
LEDs, while only C5/C7 uses green ones. Despite, in base-files
WDR4900 is actually set up with "blue" for the mentioned LEDs.
Thus, this patch creates a separate LED struct for WDR4900, so the
LEDs can be set up correctly. Despite, the wlan5g LED is removed as
it is controlled by ath9k chip for WDR4900 (in contrast to C5/C7).
Note: While front LEDs are blue, USB LEDs (on the back) are green,
so colors are mixed intentionally for the WDR4900 v2.
