[ Upstream commit c374839f9b4475173e536d1eaddff45cb481dbdf ]
Macronix NAND Flash devices are available in different configurations and densities.
MX"35" means SPI NAND MX35"LF"/"UF" , LF means 3V and UF meands 1.8V MX35LF"2G" , 2G means 2Gbits MX35LF2G"E4"/"24"/"14", E4 means internal ECC and Quad I/O(x4) 24 means 8-bit ecc requirement and Quad I/O(x4) 14 means 4-bit ecc requirement and Quad I/O(x4)
MX35LF2G14AC is 3V 2Gbit serial NAND flash device (without on-die ECC) https://www.mxic.com.tw/Lists/Datasheet/Attachments/7926/MX35LF2G14AC,%203V,...
MX35UF4G24AD/MX35UF2G24AD/MX35UF1G24AD is 1.8V 4Gbit serial NAND flash device (without on-die ECC) https://www.mxic.com.tw/Lists/Datasheet/Attachments/7980/MX35UF4G24AD,%201.8...
MX35UF4GE4AD/MX35UF2GE4AD/MX35UF1GE4AD are 1.8V 4G/2Gbit serial NAND flash device with 8-bit on-die ECC https://www.mxic.com.tw/Lists/Datasheet/Attachments/7983/MX35UF4GE4AD,%201.8...
MX35UF2GE4AC/MX35UF1GE4AC are 1.8V 2G/1Gbit serial NAND flash device with 8-bit on-die ECC https://www.mxic.com.tw/Lists/Datasheet/Attachments/7974/MX35UF2GE4AC,%201.8...

This is already in the 5.10.y tree, why are you asking for it to be applied again?
I accidentally sent the wrong patch, which has already been applied to LTS. I would like to inquire about the possibility of reverting this patch.
Revert what, the one that is in the tree already? If you need/want it reverted, please submit a patch to do so along with the reasoning, like any other change that is submitted here.
thanks,
