Adding OpenWrt support for Xiaomi "Redmi Router AX6S"/"Xiaomi Router AX3200"

[panton]

@namidairo

I'm guessing I probably made an oopsie with the definition of the OOB size?

Either that or some shenanigans occurring with the mediatek BBT/BBM.

Edit: Hmm that could be it, the bootloader looks like it has it defined as 128 for the chip with id C8,51 (The OOB size seems to be +0xA after the nand id if you look in U-Boot)

Thank you, I've changed SNAND_MEMORG_1G_2K_64 to SNAND_MEMORG_1G_2K_128 and it works great now

Here's firmware I built

based on @namidairo ax6s branch, but with fix above
additional packages:
