The s3c6410 sdhci controller does not support the 'End' attribute and NOP
attribute in the same 8-Byte ADMA descriptor. This patch adds a new quirk
to identify sdhci host contollers with such behaviour. In addition to
this, for controllers using the new quirk, the last entry in the ADMA
descritor table is marked with the 'End' attribute (instead of using a NOP
descriptor with 'End' attribute).

Unfortunately some architectures #define their read{b,w,l} and
write{b,w,l} I/O accessors which makes the SDHCI I/O accessor functions of
the same names subject to preprocessing. This leads to the following
compiler error,
In file included from drivers/mmc/host/sdhci.c:26:
drivers/mmc/host/sdhci.h:318:35: error: macro "writel" passed 3 arguments, but takes just 2
Rename the SDHCI I/O functions so that CONFIG_MMC_SDHCI_IO_ACCESSORS can
be enabled for architectures that implement their read{b,w,l} and
write{b,w,l} functions with macros.

Atmel-mci support for SDIO interrupts. This adds the enable_sdio_irq()
function and the configuration of sdio irq mask per slot. With this irq
mask information, we keep the idea of multiple slot per sd/mmc host (not
only A and B). MMC_CAP_SDIO_IRQ is added according to slot configuration.
A new little function is added to run mmc_signal_sdio_irq() during
interrupt handling routine.

The omap850 and omap730 use 16-bit registers instead of 32-bit, requiring
a modification of the register addresses in the mmc-omap driver. To
resolve this, a bit shift is performed on base register addresses, either
by 1 or 2 bits depending on the CPU in use. This yields the correct
registers for each CPU.

On some platforms like DM355, the number of EDMA parameter slots available
for EDMA_SLOT_ANY usage are few. In such cases, if MMC/SD uses 16 slots
for each instance of MMC controller, then the number of slots available
for other modules will be very few.
By passing the number of EDMA slots to be used in MMC driver from platform
data, EDMA slots available for other purposes can be controlled.
Most of the platforms will not use this platform data variable. But on
DM355, as the number of EDMA resources available is limited, the number of
scatter- gather segments used inside the MMC driver can be 8 (passed as
platform data) instead of 16. On DM355, when the number of scatter-gather
segments was reduced to 8, I saw a performance difference of about
0.25-0.4 Mbytes/sec during write. Read performance variations were
negligible.

When we moved to using ~/.perfconfig to set the value of use_browser,
it changed from a boolean to an int so that the convention used for
use_pager was followed.
That convention is:
-1: unspecified, that is what use_{browser,pager} is initialized
0: Don't use the browser (should be TUI), because was explicitely
set to 0/off/false on ~/.perfconfig [tui] cmd =, or because
we're redirecting the stdout to a file or piping it to some
other command (!isatty()).
1: Use the TUI
Some code was not properly audited and continued testing it as a
boolean, this seems to be the last one.

With port configured with PCR_FRM_SYNC_OUTPUT* and external clock, bringing
the hdlcX interface up and down without active clock supplied to the HSS
causes a TX lockup. We don't support channelized/partial interfaces so
FRaMe signals can't be used anyway, disabling them makes the lockup go away.
Changes to this logic will be required if we want to support channelized
HSS mode (this is most probably bug in NPE-A HSS firmware).

This patch reorganises the sa1111_resume() function in a manner the spinlock
happens after calling the sa1111_wake(). This fixes two bugs:
1) This function called sa1111_wake() which tried to claim the same spinlock
the sa1111_resume() already claimed. This would result in certain deadlock.

This adjusts the clockrate for the MTU timer. On the different
UX500 variants this rate is different. The platform can also have
been set up at hardware initialization, bootloader or early init
for different clock speeds. To have the clock framework available
early so the timers can use them, the clock initialization for
Nomadik and ux500 is moved to IRQ init time. A custom per-clock
callback is added to handle special cases like this.
This solves a user-visible bug: without this patch the current
UX500 platforms will not be synchronized to wall-clock time and
the platform will drift in time.
