This patch series:

• sync spinand driver code with linux-6.10
• sync spinand flash support with linux-6.10
• add initial support of ecc engines

Up to now only software ecc is supported, but other engines can be add quite easily

Is there a uclass for ECC?

Not that I am aware of. Indeed maybe a uclass for these engines might make sense (maybe UCLASS_ECC_ENGINE). The uclass for them might be simple enough just to match devices with drivers and drivers and perhaps expose the few callbacks needed (like init/prepare/finish/cleanup). Then in the NAND layer when looking for a suitable device you could do a research by class ID.

Thanks, Miquèl
