Merge tag 'armsoc-multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC multiplatform code changes from Olof Johansson:
 "The changes here belong to two main platforms:

   - Atmel At91 is flipping the bit and going multiplatform.  This
     includes some cleanups and removal of code, and the final flip of
     config dependencies

   - Shmobile has several platforms that are going multiplatform, but
     this branch also contains a bunch of cleanups that they weren't
     able to keep separate in a good way.  THere's also a removal of one
     of their SoCs and the corresponding boards (sh7372 and mackerel)"

-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.

-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
