fa47a28661 mmc: access mxcmmc from mx31 boards
This patch modifies mxcmmc.c to be used
not only by i.MX27 but also by i.MX31 boards.
Both use the same SD controller, but have different
clock set-ups.
The i.MX27 imx_get_XXXclock functions are made static to
generic.c and a public mxc_get_clock() function
is provided.  Pins, base address and prototypes for
an i.MX31 specific board_init_mmc() are provided.
Some of the i.MX27 clock getters are unused and marked
as such to avoid warnings (./MAKEALL -s mx27), but
the code was left in for future use.

f59021791b OMAP SPL: Fix missing timer_init() call in OMAP4 s_init()
In 8775471bb, the call to timer_init() was removed from common code
and put in OMAP3 s_init() function. As a result the boot was broken
on OMAP4. This patch adds timer_init() in OMAP4 s_init(), that fix
boot on all OMAP4 boards.

0ae056510f OMAP3: Correct get_sdr_cs_offset mask
The function get_sdr_cs_offset reads the CS_CFG register in the SDRC
to determine where CS1 is mapped to.  make_cs1_contiguous() will set
CS1 to follow after CS0.  The CS_CFG register has values in bits 9:8
and 3:0 but we had erroneously been testing 5:4 and 3:0 resulting in
incorrect offsets on platforms with less than 128MB as 3:0 describe
128MB hunks and 9:8 describe 32MB offsets after the 128MB hunk.

4850ab9a4f tegra2: Fix conflicting pinmux for UARTA
Tegra appears to boot with function UARTA pre-selected on mux
group SDB. If two mux groups are both set to the same function,
it's unclear which group's pins drive the RX signals into the
HW module. For UARTA, SDB certainly overrides group IRTX in
practice. To solve this, configure some alternative function on
SDB to avoid the conflict. Also, tri-state the group to avoid
driving any signal onto it until we know what's connected.

Commit 2f3427c added noop cache functions implementation for arm926ejs
to fix compilation of drivers depending on these functions (DaVinci
EMAC in particular).

Unfortunately, the bug was introduced: noop implementation calls
dcache_disable which calls flush_dcache_all which in turn calls
dcache_disable thus creating an infinite loop.

This patch removes noop implementation for flush_dcache_all, we already
have default one in arch/arm/lib/cache.c and it should be used instead.

8ba1604d34 M28: Cleanup memsize.o OOT build
The current way memsize.c is built just made a symlink into the directory
with SPL and then compiled it like any other file there. This was bad as that
broke the out-of-tree build.

The new way introduced in this patch uses the standard spl/Makefile methods
(CONFIG_SPL_LIBCOMMON_SUPPORT / CONFIG_SPL_LIBGENERIC_SUPPORT) to let files in
common/ be built. Because common/Makefile says memsize.c is always built (SPL
and non-SPL build), this fixes our issue with memsize.c out-of-tree build.

18936ee2ad i.mx: introduce the armv7/imx-common folder
In order to support the coming MX6 platform and to reducde
the duplicated code, we had better move some common files
or functions to the imx-common folder for sharing.

This patch does the following:
- move speed.c file from armv7/mx5/speed.c to armv7/imx-common/speed.c
- move armv7/mx5/timer.c to armv7/imx-common/timer.c, no any new feature
  added but just fix the checkpatch errors in the old file and remove
  the CONFIG_SYS_MX5_CLK32 reference in the file
- create one new file cpu.c file to store the common function with i.mx5/6
