Subject: [PATCH] omap34xx: SPL: enable MMC raw boot with u-boot.img
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.
