ARM: dma-mapping: fix for speculative prefetching
ARMv6 and ARMv7 CPUs can perform speculative prefetching, which makes
DMA cache coherency handling slightly more interesting. Rather than
being able to rely upon the CPU not accessing the DMA buffer until DMA
has completed, we now must expect that the cache could be loaded with
possibly stale data from the DMA buffer.
Where DMA involves data being transferred to the device, we clean the
cache before handing it over for DMA, otherwise we invalidate the buffer
to get rid of potential writebacks. On DMA Completion, if data was
transferred from the device, we invalidate the buffer to get rid of
any stale speculative prefetches.

omap: McBSP: Use cache when modifying individual register bits
Change the way McBSP registers are updated: use cached values instead of
relying upon those read back from the device.
With this patch, I have finally managed to get rid of all random
playback/recording hangups on my OMAP1510 based Amstrad Delta hardware. Before
that, values read back from McBSP registers to be used for updating them
happened to be errornous.
From the hardware side, the issue appeared to be caused by a relatively high
power requirements of an external USB adapter connected to the board's printer
dedicated USB port.
I think there is one important point that makes this patch worth of applying,
apart from my hardware quality. With the current code, if it ever happens to
any machine, no matter if OMAP1510 or newer, to read incorrect value from a
McBSP register, this wrong value will get written back without any checking.
That can lead to hardware damage if, for example, an input pin is turned into
output as a result.

There are several places where readw()/writew() functions are used instead of
OMAP_MCBSP_READ()/WRITE() macros for manipulating McBSP registers. Replace
them with macros to ensure consistent behaviour after caching is introduced.

EMMC can have two voltage supplies, Vcc and VccQ
which are implemented in the code as consumer
supplies vmmc and vmmc_aux.
If the regulator that supplies vmmc_aux is shared
with other consumers, then sending it to sleep
will disrupt those consumers. However, the
TWL4030-family regulators may have OFF remapped
to SLEEP, in which case 'regulator_disable()'

This patch moves the setup code for GPIO's and Voltage
Regulators from the board file mmc-twl4030.c to the
driver omap_hsmmc.c. PBIAS and other system control
configuration remains in the board file.
Moving GPIO code to the driver makes the board initialisation
code independent of when GPIO's are defined. That makes the
board initialisation now entirely independent of its original
twl4030 roots.
Moving Voltage Regulator code to the driver allows for further
development of regulator support in the core MMC code. It also
permits the MMC core to be compiled as a module, because the
board code no longer calls MMC core functions.
