By defining CONFIG_SYS_NAND_USE_READY the GPMC NAND driver makes use of the ready pin / signal for busy / ready detection. This function is already available but currently only used in SPL. I don't see a reason to not use it in the main U-Boot as well. As it increases the NAND performance.

I'm making it configurable, so that boards that might now have this pin connected are still supported.

I don't think we need to make this configurable. I think it's always been an oversight since we've always done this in NAND for SPL and I can't think of any boards that do support NAND but don't support booting from NAND in U-Boot.
