[PATCH v2 2/8] aspeed: Load eMMC first boot area as a boot rom

[Cédric Le Goater]

From: Cédric Le Goater <c...@kaod.org>

The first boot area partition (64K) of the eMMC device should contain
an initial boot loader (u-boot SPL). Load it as a ROM only if an eMMC
device is available to boot from but no flash device is.
