I need to revise the commit message for this patch. The script is not fixed to the first partition of the selected MMC, it scans the disk for partitions marked bootable, then checks each one of those until it finds the imxboard_efi.fd binary. We could switch over to using the generic load from CONFIG_CMD_FS_GENERIC if there's demand for non-FAT filesystems. We're currently using fatload because the EFI partitions in our Windows images are always FAT formatted.
