spl: spl_mmc: Add option to boot from a MMC partition with offset
This patch introduces the option to boot from a MMC card parition with an offset. This can be done by using both defines together: define CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION 1 define CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR ((160 << 10) / 512) The example above loads the main U-Boot at offset 160KiB from the MMC partition 1.
