8bac5dc18a mediatek: add new layout for Xiaomi Redmi Router AX6000 for OpenWrt U-Boot
This new layout is only bootable with OpenWrt U-Boot. It reuses the
two crash partions and expands the ubi partion to the end of whole flash.

Do not use this layout with stock U-Boot!

18bea173a6 mediatek: add alternative stock layout for Xiaomi Redmi Router AX6000
In this implementation, the flash partition layout is adjusted to avoid
modifying the uboot environment of mtdparts. This ensures that the 30M
ubi_kernel partition remains aligned with the stock ubi partition, and
the kernel volume is placed in it. This allows the stock uboot to boot
from it without changing the mtdparts, which is useful for reverting back
to the stock firmware using Xiaomi Firmware Tools. In actual testing,
modifying mtdparts has been found to break Xiaomi Firmware Tools.

1. use ARTIFACTS to generate initramfs-factory.ubi for easy installation.
2. The NAND flash layout is changed to allow for reverting back to the
   stock firmware.
3. Before performing sysupgrade, do some cleanup in platform_pre_upgrade
   to ensure a clean installation of OpenWRT.
4. Setup the uboot env to ensure that the system always boot, which can
   be helpful for users who may forget to do this before sysupgrade in
   the initramfs.

New flash instructions:
1. Gain ssh access. Please refer to:
   https://openwrt.org/toh/xiaomi/redmi_ax6000#installation)

2. Check which system current u-boot is loading from:
   COMMAND: `cat /proc/cmdline`
   sample OUTPUT: `console=ttyS0,115200n1 loglevel=8 firmware=1 uart_en=1`
   if firmware=1, current system is ubi1
   if firmware=0, current system is ubi0

3. Setup nvram and write the firmware:
   If the current system is ubi1, please set it up so that the next time
   it will boot from ubi, and write the firmware to ubi:
```
nvram set boot_wait=on
nvram set uart_en=1
nvram set flag_boot_rootfs=0
nvram set flag_last_success=0
nvram set flag_boot_success=1
nvram set flag_try_sys1_failed=0
nvram set flag_try_sys2_failed=0
nvram commit
ubiformat /dev/mtd8 -y -f /tmp/initramfs-factory.ubi
```
   If the current system is ubi, please set it up so that the next time
   it will boot from ubi1, and write the firmware to ubi1:
```
nvram set boot_wait=on
nvram set uart_en=1
nvram set flag_boot_rootfs=1
nvram set flag_last_success=1
nvram set flag_boot_success=1
nvram set flag_try_sys1_failed=0
nvram set flag_try_sys2_failed=0
nvram commit
ubiformat /dev/mtd9 -y -f /tmp/initramfs-factory.ubi
```

4. After rebooting, the system should now boot into the openwrt initramfs.
   Flash the squashfs-sysupgrade.bin via using ssh or luci.
```
sysupgrade -n /tmp/squashfs-sysupgrade.bin
```
Done.

For existing users of the Redmi AX6000 running OpenWrt, here are the steps to
switch to this new layout:

1. Flash initramfs-factory.ubi
```
mtd -r -e ubi write /tmp/initramfs-factory.ubi ubi
```

2. After rebooting, the system will boot into the new openwrt-initramfs.
Log in and perform a sysupgrade to complete the process.
```
sysupgrade -n /tmp/squashfs-sysupgrade.bin
```

641e4f2f04 mediatek: add Xiaomi Redmi Router AX6000 support
Hardware specification:
  SoC: MediaTek MT7986A 4x A53
  Flash: ESMT F50L1G41LB 128 MB
  RAM: K4A4G165WF-BCWE 512 MB
  Ethernet: 4x 10/100/1000 Mbps
  WiFi1: MT7976GN 2.4GHz ax 4x4
  WiFi2: MT7976AN 5GHz ax 4x4
  Button: Mesh, Reset

Flash instructions:
  1. Gain ssh and serial port access, see the link below:
     https://openwrt.org/toh/xiaomi/redmi_ax6000#installation
  2. Use ssh or serial port to log in to the router, and
     execute the following command:
     nvram set boot_wait=on
     nvram set flag_boot_rootfs=0
     nvram set flag_boot_success=1
     nvram set flag_last_success=1
     nvram set flag_try_sys1_failed=8
     nvram set flag_try_sys2_failed=8
     nvram commit
  3. Set a static ip on the ethernet interface of your computer
     (e.g. default: ip 192.168.31.100, gateway 192.168.31.1)
  4. Download the initramfs image, rename it to initramfs.bin,
     and host it with the tftp server.
  5. Interrupt U-Boot and run these commands:
     setenv mtdparts nmbm0:1024k(bl2),256k(Nvram),256k(Bdata),2048k(factory),2048k(fip),256k(crash),256k(crash_log),112640k(ubi)
     saveenv
     tftpboot initramfs.bin
     bootm
  6. After openwrt boots up, use scp or luci web
     to upload sysupgrade.bin to upgrade.

Revert to stock firmware:
  Restore mtdparts back to default, then use the
  vendor's recovery tool (Windows only).

1a6f6a1e8c mediatek: bpi-r3: make initramfs/recovery optional
Only include recovery image in SD card image generated for the
BananaPi BPi-R3 if building with CONFIG_TARGET_ROOTFS_INITRAMFS.
This allows to build images larger than 32 MB (the limit for
initramfs/recovery image) by deselecting initramfs.
