f22f156e0b Make this work on the AT91SAM9G20: 
o Disable multi-block operations: they sometimes fail.
o Don't use the PROOF bits yet: they hang the system hard.
o Disable the the multi-block operations for !rm9200, but it
  still doesn't help.
o Fix writing < 12 bytes errata to actually work.
o Enable, for the moment, reporting extra bytes soaked up.

683bb97c9f When copying data, use memcpy instead of bcopy. It matches the 
arguments better.
Also, set the need to use the workaround flag before we actually need
to use it, rather than after.

d7f8f1facd Clip the upper end to 31MHz for slow clock speeds. On faster

0f30f5d36b Bring in the multi-block patches for mci. These required extensive 
restructuring of the driver.  I've tried to preserve the other silicon
workarounds that we've added over the years, but haven't had a chance
to extensively test on other hardware.  On my AT91RM9200 with 30MHz/1
wire/64 block transfers, I've been able to go from ~.66MB/s to
2.25MB/s in the simple tests I performed, almost a 3.5x improvement.
This cuts the boot time almost in half when everything else goes
right (timed from rtc message to login: prompt).

b8e36ef7e0 Don't puprosely overclock the SD bus to 30MHz, make the user 
explicltly enable that.  The driver chose to use 60MHz / 2 (30MHz)
most of the time rather than 60MHz / 4 (15MHz) based on the Linux
driver of the time.  This pushes the spec a little in order to not
suffer the penalty of running at 15MHz.  However, when other bus
masters are active in the system, and the user tries 4-wire mode, the
internal bus arbitration would fail with data loss as a result.

8634a69af0 Do not change "cachable" attribute for DMA memory allocated with 
BUS_DMA_COHERENT attribute

The minimum unit for changing "cachable" attribute is page, so call
to pmap_change_attr effectively disable cache for all pages that newly
allocated DMA memory region spans on. The problem is that general-purpose
memory could reside on these pages too and disabling cache might affect
performance. Moreover ldrex/strex operators raise Data Abort exception
when accessing memory on page with "cachable" attribute off.

BUS_DMA_COHERENT does nto require memory to be coherent. It just suggests
to do best effort for reducing synchronization overhead.

8bfdf49b97 - Calculate the I2C baud rate to keep them <100 kHz under different TCLK 
frequencies.  The maximum freqency is 100 kHz according to the datasheet.

- Add child device probing support based on the device tree.  It now tries to
  find i2c-address property in the tree and attach the device with given slave
  address to iicbus.
