From: Cheng Ming Lin <chengminglin@mxic.com.tw>
commit c374839f9b4475173e536d1eaddff45cb481dbdf upstream.
MX35UF{1,2,4}GE4AD and MX35UF{1,2}GE4AC have been
merged into Linux kernel mainline through upstream commit.
For SPI-NAND flash support on Linux kernel LTS v5.4.y,
add SPI-NAND flash MX35UF{1,2,4}GE4AD and MX35UF{1,2}GE4AC in id tables.
Those five flashes have been validated on Xilinx zynq-picozed board and
Linux kernel LTS v5.4.y.

No, this isn't that commit, it's just a portion of it :(
Please backport the whole thing, and leave the original signed-off-by
lines and text in it.
Also, this is needed for 5.10.y kernels, right? Please provide a
backported version for there, otherwise you would upgrade your kernel
and have a regression.
thanks,
greg k-h
