+-ROM-able zImage boot from MMC

+-An ROM-able zImage compiled with ZBOOT_ROM_MMCIF may be written to MMC and

+-
+-This is achieved by the mask ROM 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.
+-
+-This code has been tested on an AP4EB board using the developer 1A eMMC
+-boot mode which is configured using the following jumper settings.
+-The board used for testing required a patched mask ROM in order for
+-this mode to function.

+-ROM-able zImage boot from eSD
+------------------------------
+-
+-An ROM-able zImage compiled with ZBOOT_ROM_SDHI may be written to eSD and
+-SuperH Mobile ARM will to boot directly from the SDHI hardware block.
+-
+-This is achieved by the mask ROM 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.

+-   x|x|x|x| |x|x|
+-S4 -+-+-+-+-+-+-+-
+-    | | | |x| | |x on
+-
+-The eSD card needs to be present in SDHI slot 1 (CN7).
+-As such S1 and S33 also need to be configured as per
+-the notes in arch/arm/mach-shmobile/board-mackerel.c.
+-
+-A partial zImage must be written to physical partition #1 (boot)
+-of the eSD at sector 0 in vrl4 format. A utility vrl4 is supplied to
+-accomplish this.
+-
+-e.g.
+-	vrl4 < zImage | dd of=/dev/sdX bs=512 count=17
+-
+-A full copy of _the same_ zImage should be written to physical partition #1
+-(boot) of the eSD at sector 0. This should _not_ be in vrl4 format.
+-
+-	vrl4 < zImage | dd of=/dev/sdX bs=512
+-
+-Note: The commands above assume that the physical partition has been
+-switched. No such facility currently exists in the Linux Kernel.
+-
+-Physical partitions are described in the eSD specification.  At the time of
+-writing they are not the same as partitions that are typically configured
+-using fdisk and visible through /proc/partitions
