Remove ZBOOT MMC/SDHI Documentation for sh7372 together wit the vrl4 utility. Without sh7372 and Mackerel support these files are no longer useful.

Here is my latest attempt (V2) of legacy board and SoC support removal for Mackerel and sh7372. Both the ARM mach-shmobile code base and the PINCTRL subsystem is affected.

Also get rid of the remaining ZBOOT MMC/SDHI code, documentation and utility that has no user once sh7372 is gone.

The Cortex-A8 based sh7372 SoC is rather old and never went into mass production anyway, so these patches that remove SoC and board support will only affect a few selected developers.

I wish we had some way to make use of the ZBOOT MMC/SDHI code, but without any board or SoC code it makes little sense to keep it.

Thanks to Laurent and Geert for review!

Here is my latest attempt (V2) of legacy board and SoC support removal for Mackerel and sh7372. Both the ARM mach-shmobile code base and the PINCTRL subsystem is affected.

Also get rid of the remaining ZBOOT MMC/SDHI code, documentation and utility that has no user once sh7372 is gone.

The Cortex-A8 based sh7372 SoC is rather old and never went into mass production anyway, so these patches that remove SoC and board support will only affect a few selected developers.

I wish we had some way to make use of the ZBOOT MMC/SDHI code, but without any board or SoC code it makes little sense to keep it.

Thanks to Laurent and Geert for review!

Sad to see all our hard work being deleted. But at the same time its nice to be able to reduce our footprint by 8681 lines!

I have queued up the first 12 patches of this series, that is the non-pfc patches. They are queued up in a new sh7372-soc-removal-for-v3.21 branch which I intend to push as part of renesas-devel-20150127-v3.19-rc6 a little later today.

With regards to the PFC patches, the last two patches in the series, I have spoken with Laurent about this and my understanding is that his feeling is that they could be merged independently by the pinctl maintainer, Linus Walleij.

Laurent, if that is correct could see about working with Linus towards that goal? If not, please let me know and we can work out another plan.

I have queued up the first 12 patches of this series, that is the non-pfc patches. They are queued up in a new sh7372-soc-removal-for-v3.21 branch which I intend to push as part of renesas-devel-20150127-v3.19-rc6 a little later today.

BTW, could you check that I queued up things correctly?
