Uwe Kleine-König 3bd7f80d8f mci: mxs: support overwriting the device name via platform data
The current implementation of the bootloader specification depends on the
hardware name and the name of the device in /dev to match. As the default
hardware name is mciX and the device name is diskY the bootloader spec
cannot be used as is.

This patch implements a way to overwrite the device name similar to what is
possible for the imx-esdhc driver.

Markus Niebel e3ab3078dc MCI: imx-esdhc: implement workaround for errata ENGcm12360
At least i.MX53 has errata ENGcm12360:

Occurs when a pending command which issues busy is completed.
For a command with R1b response, the proper software sequence
is to poll the DLA for R1b commands to determine busy
state completion. The DLA polling is not working properly for
the ESDHC module. This is relevant for all eSDHC ports (eSDHC1-4 ports)

DLA bit in PRSSTAT register cannot be
polled to wait for busy state completion.

Updated block guide to reflect that DLA is not applicable to detect
busy state, instead, should poll bit 24 in PRSSTAT register (DLSL[0] bit)
to check that wait busy state is over.

Sascha Hauer ca13a84ac2 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.

MMC/SD cards normally have a DOS/GPT partition table, but sometimes

Sascha Hauer dee6282fbf 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.
