This enables support for booting from NAND internalmemory. U-Boot SPL doesn't detect where is it load from,therefore this option is needed to properly load image fromflash. Option also disables MMC functionality on U-Boot due toinitialization errors encountered, when both controllers areenabled.Is this last bit a bug in the s/w or a hardware thing? Does this mean that MMC is not available in the main u-boot image too when NAND support is enabled?
I'm not sure what is a reason, but controller can't initialize MMC when SPL is loaded. MMC works in main u-boot allowing to boot from it and perform any other option (rescan, part, info, etc.). It is only SPL relevant.
How strange! Hans, do you have any ideas about why this might be the case? Is there some overlap between MMC and NAND? I can't think what...
