A previous attempt to simplify things went wrong and now sysupgrade
is broken on this device. Fix that.

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!

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
```

Instead of trying to figure out the actual root device, just use the
kernel 'root' cmdline parameter as a hint to decide which device to
flash to.

A line in platform.sh was accidentally removed when adding support
for the Bananapi BPi-R3.
Re-add it to fix sysupgrade on the MTK7986 rfba AP.

The Bananapi BPi-R3 is a development router board built around the
MediaTek Filogic 830 (MT7986A) SoC.
The board can boot either from microSD, SPI-NAND, SPI-NOR or eMMC.
Only either SPI-NAND or SPI-NOR can be used at the same time, also only
either microSD or eMMC can be used. The various storage options can be
selected using small SMD switches on the board.
Specs:
* MediaTek MT7986A (Filogic 830) 4x ARM Cortex A53
* 4T4R 2.4G 802.11bgnax (MT7975N)
* 4T4R 5G 802.11anac/ax (MT7975P)
* 2 GB DDR4 RAM
* 8 GB eMMC
* 128 MB SPI-NAND flash
* 32 MB SPI-NOR flash
* on-board MT7531 GbE switch
* 2x SFP+ (1 GbE / 2.5 GbE)
* 5x GbE network port
* miniPCIe slot (only USB 2.0 connected)
* uSIM slot (connected to miniPCIe interface)
* M.2 KEY-E PCIe interface (PCIe x2)
* microSD card interface
* 26 PIN GPIO
Hardware details: https://wiki.banana-pi.org/Banana_Pi_BPI-R3
Working:
* all 4 boot methods incl. installation via U-Boot, sysupgrade, ...
* copper LAN and WAN ports
* SFP1 (connected to gmac1, eth1 in Linux)
* WiFi
* LEDs
* Buttons
* PSTORE/ramoops based dual-boot
Not Working (missing driver features):
* SFP2 (connected to MT7531 switch)
Untested:
* M.2/NGFF slot (PCIe x2)
* mPCIe slot (USB 2.0 + SIM)

Initially this covers MT7986 only, but it will later be expanded to cover other
Filogic branded platforms by MediaTek
