Yes, I have considered that. However, it would make the #define rather confusing
for the rest.

It looks like another fix for this bug is to leave the current code
alone and turn off CONFIG_MTD_NAND_ECC_SMC.
This could be a better fix if this is the way u-boot currently works.
Has anybody verified if the current u-boot has the ECC problem?
