MX28: MMC: Avoid DMA DCache race condition
This patch prevents dcache-related problem. The problem manifested
itself on the SPI driver, this is just a port to the MMC driver.
The scenario is the same. In case an "mmc read" is issued to a
buffer which was written right before it and data cache is enabled,
the cache eviction might happen during the DMA transfer into the
buffer, therefore corrupting the buffer. Clear any cache lines that
might contain the buffer to prevent such issue.

MX28: SPI: Fix the DMA chaining
It turns out that in order for the SPI DMA to properly support
continuous transfers longer than 65280 bytes, there are some very
important parts that were left out from the documentation.
Firstly, the XFER_SIZE register is not written with the whole length
of a transfer, but is written by each and every chained descriptor
with the length of the descriptors data buffer.
Next, unlike the demo code supplied by FSL, which only writes one PIO
word per descriptor, this does not apply if the descriptors are chained,
since the XFER_SIZE register must be written. Therefore, it is essential
to use four PIO words, CTRL0, CMD0, CMD1, XFER_SIZE. CMD0 and CMD1 are
written with zero, since they don't apply. The DMA programs the PIO words
in an incrementing order, so four PIO words.
Finally, unlike the demo code supplied by FSL, the SSP_CTRL0_IGNORE_CRC
must not be set during the whole transfer, but it must be set only on the
last descriptor in the chain.

MX28: SPI: Fix the DMA DCache race condition
This patch fixes dcache-related problem. The problem manifested
when dcache was enabled and the following command issued twice:
mw 0x42000000 0 0x4000 ; sf probe ; sf read 0x42000000 0x0 0x10000 ; sha1sum 0x42000000 0x10000
The SHA1 checksum was correct during the first call. Yet with
every subsequent call of the above command, it differed and was
wrong.
It turns out this was because of a race condition. On the first
time the command was called, no cacheline contained any data from
the destination memory location. The DMA transfered data into the
location and the cache above the location was invalidated. Then the
checksum was computed, but that meant the data were loaded into data
cache.
On any subsequent call, the DMA again transfered data into the same
destination. Yet during the transfer, some of the DCache lines were
evicted and written back into the main memory. Once the DMA transfer
completed, the data cache was invalidated over the memory location as
usual. But the data that were to be loaded back into the data cache
by subsequent SHA1 checksuming were corrupted.

efikamx: refine USB support
Because of the way USB pad settings are handled it doesn't make sense to
be able to build the Efika MX board support without CONFIG_CMD_USB turned
on. So, we change the build to always compile in USB support.
We do not need to check for CONFIG_CMD_USB like we do with CONFIG_MXC_SPI
since the USB subsystem will error out of the compile for us.
Additionally, the following behaviors have changed;
* Smartbook "preboot" should not set input and output to USB keyboard as
there is no display support
* board_eth_init is implemented such that it does not cause U-Boot to
report an explicit failure ("CPU Net Initialization Failed").
Since Ethernet is implemented via USB (fixed on Smarttop, pluggable on
Smartbook, and handled by "usb start") - the warning that is left
("No ethernet found") is perfectly reasonable at the point it is printed
since the USB system hasn't been started and nothing has been probed yet.

efikamx: sync Smartbook DDR settings in DCD with those found in Genesi's production U-Boot
We have no idea where the DCD was derived from for Smartbook support, but they
differ from the Smarttop settings, MX51EVK settings and certainly don't
correspond to any shipped or development version of U-Boot that Genesi has ever
had on any Smartbook.
So, copy the calibrated, verified settings from the U-Boot as shipped with every
Smartbook since retail production. Remove those few settings that just set the
POR defaults which have already been confirmed for the previous Smarttop DCD
change.
One of the lines is specific to i.MX51 TO3 designs and therefore TO2 Smartbooks
will possibly not work so reliably with this new DCD; that said, TO2 Smartbooks
basically don't exist at retail and the number of units in the world is less
than 5 (3 of which are at the Genesi office or owned by Genesi employees).
Many hours of memory testing confirms the new settings are stable.

efikamx: update to Efika MX Smarttop and Smartbook boards
This is a rework of a previously submitted patchset and bundles the

* Use iomux-mx51.h include to simplify board configuration.
* Simplify LED support (remove efikamx_toggle_led, change lit LEDs).
* Simplify MMC support for CD and WP pin differences.
* Fix broken CPU voltage setting - comment said 1.1V but the code set to
1.2V. It should never have been set to 1.2V even on i.MX51 TO2 and
all available Linux kernels would drop the voltage to 1.1V anyway and

PCBID pads seem to need time to settle due to external pulldowns, otherwise
we are reading floating GPIO pins with implicit pad pullups and get the wrong

since timers are not available. The time taken to get from DCD to the code
requiring the pads set seems to be more than long enough (even with caches
enabled).
We have space in the DCD due to the DDR settings changes to configure all
the pad settings we need for this, plus the LED pad settings too which
reduces the amount of code required later on.

Efika MX boards configure their DDR pad settings twice, one in the DCD generated
from imximage_*.cfg and again in init_drive_strength called before relocation.
Rather than doing this, roll the changes it makes into the DCD so DDR is set up
before a single line of code in U-Boot is run.
The settings are identical with this DCD block which is shorter (by 7 entries)
than the old one, and after the output of init_drive_strength since a lot of the
functionality in the existing DCD and init_drive_strength function was just
setting the POR defaults. This goes to explain some now-missing entries.
