Warner Losh 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.

Warner Losh 062223cd29 Make AT91_MCI_ALLOW_OVERCLOCK a real option. Rename old use 30MHz to 
this new option.  Only try to use > 25MHz when our best frequency is <
15MHz and overclocking is enabled. Fix minor style chaff.

Warner Losh d7f8f1facd Clip the upper end to 31MHz for slow clock speeds. On faster 
machines, we wind up with a 66MHz clock, which is too fast.

Warner Losh f589a026d5 Move to using a flag instead of checking the CPU type each 
transaction for the MCI1 rev 2.x write workarounds.

Warner Losh c35e1c5bbc Style: Move these routines to be before the forward declared functions 
as is the normal practice.

Warner Losh 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).

Break down the bytes directly into the softc;
the intermediate buffer isn't needed here.

Warner Losh f535f4234a Minor style(9) nit. 2012-08-27 04:08:43 +00:00
Warner Losh 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.

Oleksandr Tymoshenko 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.

Hiroki Sato 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.
