Enable support for booting U-Boot image from ext filesystem when either SD/MMC or SATA support is compiled into the SPL. This will allow easy transition from loading U-Boot image from ad-hoc offset on the card to loading U-Boot image from the filesystem. VFAT support is intently not enabled. The boot order is tweaked so that raw is tested first and if the raw has no signature, FS boot is attempted. To install just the SPL on i.MX6 board, perform the following operation $ dd if=SPL of=/dev/sdX seek=2 bs=512 To install the U-Boot image, copy u-boot.img to the first partition of the SD/MMC/SATA drive. The partition must be formated to extfs.
