I'm not sure that CONFIG_xxx_BOOT and CONFIG_SPL_xxx_SUPPORT are the same thing. For example, CONFIG_NOR_BOOT on am335x means "we are building to support booting from NOR, so include all of that stuff that's normally not included". While CONFIG_SPL_NAND_SUPPORT means include NAND support in SPL, which is not mutually exclusive with MMC, etc. -- Tom
