Paul Gortmaker 88b4767974 mmc: Add module.h to drivers/mmc users assuming implicit presence.
We are cleaning up the implicit presence of module.h; these guys are
some of the people who just assume it will be there.  Call it out
explitly for those that really need it.

Xu lei e51cbc9eab mmc: sdhci-of-esdhc: Access Freescale eSDHC registers as 32-bit
Freescale eSDHC registers only support 32-bit accesses, this patch
ensures that all Freescale eSDHC register accesses are 32-bit.

Shawn Guo f0de836923 mmc: sdhci: change sdhci-pltfm into a module
There are a couple of problems left from the sdhci pltfm and OF
consolidation changes.

* When building more than one sdhci-pltfm based drivers in the same
  image, linker will give multiple definition error on the sdhci-pltfm
  helper functions.  For example right now, building sdhci-of-esdhc
  and sdhci-of-hlwd together is a valid combination from Kconfig view.

* With the current build method, there is error with building the
  drivers as module, but module installation fails with modprobe.

The patch fixes above problems by changing sdhci-pltfm into a module.
To avoid EXPORT_SYMBOL on so many big endian IO accessors, it moves
these accessors into sdhci-pltfm.h as the 'static inline' functions.
As a result, sdhci.h needs to be included in sdhci-pltfm.h, and in
turn can be removed from individual drivers which already include
sdhci-pltfm.h.

Shawn Guo 38576af1f8 mmc: sdhci: make sdhci-of device drivers self registered
The patch turns the sdhci-of-core common stuff into helper functions
added into sdhci-pltfm.c, and makes sdhci-of device drviers self
registered using the same pair of .probe and .remove used by
sdhci-pltfm device drivers.

As a result, sdhci-of-core.c and sdhci-of.h can be eliminated with
those common things merged into sdhci-pltfm.c and sdhci-pltfm.h
respectively.

Shawn Guo e307148fd4 mmc: sdhci: eliminate sdhci_of_host and sdhci_of_data
The patch migrates the use of sdhci_of_host and sdhci_of_data to
sdhci_pltfm_host and sdhci_pltfm_data, so that the former pair can
be eliminated.

Matt Fleming dc297c92e6 sdhci: build fix: rename SDHCI I/O accessor functions
Unfortunately some architectures #define their read{b,w,l} and
write{b,w,l} I/O accessors which makes the SDHCI I/O accessor functions of
the same names subject to preprocessing.  This leads to the following
compiler error,

In file included from drivers/mmc/host/sdhci.c:26:
drivers/mmc/host/sdhci.h:318:35: error: macro "writel" passed 3 arguments, but takes just 2

Rename the SDHCI I/O functions so that CONFIG_MMC_SDHCI_IO_ACCESSORS can
be enabled for architectures that implement their read{b,w,l} and
write{b,w,l} functions with macros.
