Others like ast2600-evb could also boot from eMMC if the HW strapping boot-from-eMMC bit was set. Add a property to set or unset this bit. This is useful to test boot images. For now, only activate this property on the ast2600-evb and rainier-bmc machines for which eMMC images are available or can be built.
