The following commit enabled raw SPL booting: 22d90d560a omap3: Use raw SPL by default for mmc1 but it was reverted by the following commit: 821c89d38c Revert "omap3: Use raw SPL by default for mmc1" because SPL is unable to distinguish between RAW images and garbage.
However if CONFIG_SPL_RAW_IMAGE_SUPPORT is disabled, SPL does identify if there is a valid image with spl_parse_image_header.
With this change, and CONFIG_SPL_RAW_IMAGE_SUPPORT disabled, raw MMC boot will be tried first, and if it fails, it FS will be tried.
The two scenarios have been tested on a BeagleBoard XM Revision C1.
