Similar to usbboot, add command line to boot from raw mmc partition using common_diskboot(), which supports legacy or FIT images.
Usage: mmcboot [loadAaddr] [dev:part]
Where [loadAddr] defaults to CONFIG_SYS_LOAD_ADDR, and [dev:part] defaults to ${bootdevice}.
Also fixing config macro usage for CONFIG_SUPPORT_EMMC_BOOT (suggested by checkpatch.pl).
Can this not be implemented by some U-Boot script ? I can imagine that reading the first few bytes from the partition (mmc read) would permit you to obtain the uImage/fitImage header from the partition, from which you can obtain the image size, which is the total number of bytes to read (iminfo might help , or fdt header), and then read out the entire image and bootm it.
