[LEDE-DEV] MT7620 NAND patch and kernel 4.9

[Robert Marko]

Hi,
I am working on adding support for Xiaomi Router R3 and most of work
is already done.
https://wiki.openwrt.org/toh/xiaomi/mir3

Unfortunately, it uses NAND flash for which patch that supported it
for MT7620 was dropped when ramips was updated to kernel 4.9 so
therefore NAND does not working with code from master branch.
Meanwhile kernel 4.4 works.

So does anybody have updated patch?

Thanks
