I don't think either SD or eMMC is supported in mainline U-Boot for

Compatible strings usually come in form of "<manufacturer>,<model>", as
states in devicetree specification,

Empty board_init() function could just be omitted, as long as you set
CONFIG_BOARD_INIT to n. Please refer to this patch[1] for more
information.
