current mtd/nand/nand_base.c does in same way. We have to define CONFIG_SYS_NAND_ONFI_DETECTION. Once it is defined, it will check for normal flash detection followed by ONFI. Similar way as Linux doing.
do you have some other requirement. Regards, Prabhakar _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
