[arnd: The sh7372 platform is rather dated and is believed to
 have no active users on modern kernels. It stands in the way
 of converting all of mach-shmobile to be multiplatform capable,
 as adding pinctrl and common-clock support for it would be more
 work than it's  worth. As always, should any legitimate upstream
 users show up in the future, we will revert this removal]

* In practice this means writing a padded vrl4 header to stdout followed
* by the zImage.
*
* The padding places the zImage at ALIGN bytes into the output.
* The vrl4 uses ALIGN + START_BASE as the start_address.
* This is where the mask ROM will jump to after verifying the header.
*
* The header sets copy_size to min(sizeof(zImage), MAX_BOOT_PROG_LEN) + ALIGN.
* That is, the mask ROM will load the padded header (ALIGN bytes)
* And then MAX_BOOT_PROG_LEN bytes of the image, or the entire image,
* whichever is smaller.

* The zImage is not modified in any way.

ROM-able zImage boot from MMC
-----------------------------
An ROM-able zImage compiled with ZBOOT_ROM_MMCIF may be written to MMC and
SuperH Mobile ARM will to boot directly from the MMCIF 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.
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.
8 7 6 5 4 3 2 1
x|x|x|x|x| |x|
S4 -+-+-+-+-+-+-+-
| | | | |x| |x on
The zImage must be written to the MMC card at sector 1 (512 bytes) in
vrl4 format. A utility vrl4 is supplied to accomplish this.
e.g.
vrl4 < zImage | dd of=/dev/sdX bs=512 seek=1
A dual-voltage MMC 4.0 card was used for testing.

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.
This code has been tested on an mackerel board using the developer 1A eSD
boot mode which is configured using the following jumper settings.
8 7 6 5 4 3 2 1
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
