Do you intend to replace CONFIG_SPL_NOR_SUPPORT CONFIG_SPL_NAND_SUPPORT CONFIG_SPL_USB_SUPPORT CONFIG_SPL_MMC_SUPPORT etc. with these options? Currently, common/spl/spl.c uses CONFIG_SPL_*_SUPPORT to enable/disable capable boot devices. -- Best Regards Masahiro Yamada _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
