mci: omap: Fix default value of mci.f_max
...
With commit c2ef47887 mci.f_max default value is
only set when pdata is available.
Fix this with always setting the mci.f_max default
value and overrite it when pdata available.

ARM: MXS: introduce stmp device support
...
MXS specific devices have some common infrastructure in the kernel
known as STMP devices. We have the same in barebox, but with a
mxs_ prefix instead of a stmp_ prefix. As some STMP devices are
also found on i.MX6 move the common infrastructure out of MXS
specific files and use the stmp_ prefix.
This is done in preparation for i.MX6 NAND support.

mci: Add devicetree partition parsing
...
MMC/SD cards normally have a DOS/GPT partition table, but sometimes
barebox uses the unpartitioned area to store its environment. Add
devicetree partition parsing also for SD/MMC cards so that we have
a way to describe the partition in the devicetree.

mci: Use tran_speed field to fix highspeed MMC card clock
...
The tran_speed field as decoded from csd is valid in most cases,
so use it to determine the maximum clock we can support. It is
not valid though for MMC highspeed cards, in this case the
csd contains invalid values and we have to set tran_speed explicitly
to the maximum speed. As the values passed into mci_set_clock are
now based on tran_speed we no longer have to limit the rate to
tran_speed in mci_set_clock.
The (intended) effect of this patch is that highspeed MMC cards are
no longer limited to non highspeed rates.

later.

mci: Add support for MMC boot partitions
...
Some MMC cards support boot partitions. These are special regions
on the MMC card intended to put a bootloader on.
This patch adds support for these partitions, they are accessible
as /dev/diskx.boot[0|1].
Additionally the partitions can be configured bootable using a
device parameter. This can be used to mark the user area or one
of the boot partitions as bootable.
Since this feature is mostly seen on eMMC cards it is made optional
to lower the size impact for boards which do not have eMMC.

mci i.MX esdhc: Fix clock divider calculation

This updates the i.MX esdhc divider settings to FSLs U-Boot.
Current timings work fine for SD cards, but not for eMMC.
Although the calculation is fine according to the datasheet and reading from
eMMC works, writing is broken. Atleast on i.MX53/tqma53.
With this patch the result is the same, but uses different divider values to
achieve it.
While at it, replace the udelay with a busy-loop.
