From: Yegor Yefremov <yegorslists@googlemail.com>

OnRISC Baltos devices are based on a am335x SoC and can be booted
either from MMC or NAND.

Signed-off-by: Yegor Yefremov <yegorslists@googlemail.com>

Changes:
	v3: - make hw_param a local variable
	    - implement memory size detection
	    - remove baltos_mem_init initcall
        v2: - remove typedef
            - rework invalid EEPROM content handling
            - add mmc0 as boot device for MMC boot source
