This allows a ROM-able zImage to be written to eSD and for SuperH Mobile ARM to boot directly from the SDHI hardware block. This is achieved by the MaskROM loading the first portion of the image into MERAM and then jumping to it. This portion contains loader code which copies the entire image to SDRAM and jumps to it. From there the zImage boot code proceeds as normal, uncompressing the image into its final location and then jumping to it.
