This patch is a workaround for the 460075 Cortex-A8 (r2p0) erratum. It
configures the L2 cache auxiliary control register so that the Write
Allocate mode for the L2 cache is disabled.

This patch adds a workaround for the 458693 Cortex-A8 (r2p0)
erratum. It sets the corresponding bits in the auxiliary control
register so that the PLD instruction becomes a NOP.

This hooks the U300 support into Kbuild and makes a small hook
in mmu.c for supporting an odd memory alignment with shared memory
on these systems.
This is rebased to RMK:s GIT HEAD. This patch tries to add the
Kconfig option in alphabetic order by option text and the Makefile
entry after config symbol.

This is a significant rework of the low-level clock, PLL and Power
Sleep Controller (PSC) implementation for the DaVinci family. The
primary goal is to have better modeling if the hardware clocks and
features with the aim of DVFS functionality.
Highlights:
- model PLLs and all PLL-derived clocks
- model parent/child relationships of PLLs and clocks
- convert to new clkdev layer
- view clock frequency and refcount via /proc/davinci_clocks
Special thanks to significant contributions and testing by David
Brownell.

"""The Marvell® PXA168 processor is the first in a family of application
processors targeted at mass market opportunities in computing and consumer
devices. It balances high computing and multimedia performance with low
power consumption to support extended battery life, and includes a wealth
of integrated peripherals to reduce overall BOM cost .... """
See http://www.marvell.com/featured/pxa168.jsp for more information.
1. Marvell Mohawk core is a hybrid of xscale3 and its own ARM core,
there are many enhancements like instructions for flushing the
whole D-cache, and so on
2. Clock reuses Russell's common clkdev, and added the basic support
for UART1/2.
3. Devices are a bit different from the 'mach-pxa' way, the platform
devices are now dynamically allocated only when necessary (i.e.
when pxa_register_device() is called). Description for each device
are stored in an array of 'struct pxa_device_desc'. Now that:
a. this array of device description is marked with __initdata and
can be freed up system is fully up
b. which means board code has to add all needed devices early in
his initializing function
c. platform specific data can now be marked as __initdata since
they are allocated and copied by platform_device_add_data()
4. only the basic UART1/2/3 are added, more devices will come later.

1. introduce folder of 'arch/arm/plat-pxa' for common code across different
PXA processor families
2. initially moved DMA code into plat-pxa
3. common code in <mach/dma.h> moved into <plat/dma.h>, new processors
should implement its own <mach/dma.h>, provide the following required
definitions and '#include <plat/dma.h>' in the end:
- DMAC_REGS_VIRT for mapped virtual address of the DMA registers'
physical I/O memory

Here it is... HIGHMEM for the ARM architecture. :-)
If you don't have enough ram for highmem pages to be allocated and still
want to test this, then the cmdline option "vmalloc=" can be used with
a value large enough to force the highmem threshold down.
Successfully tested on a Marvell DB-78x00-BP Development Board with
2 GB of RAM.

The new Kconfig option to build "staging" drivers (code in
drivers/staging/) is seen in all except three architectures (arm, h8300,
cris), because in these cases arch/$ARCH/Kconfig does NOT source
drivers/Kconfig.
This patch adds the source "drivers/staging/Kconfig" to
arch/$ARCH/Kconfig for these three exceptional cases.

This patch is as small a change as possible to the KS8695 GPIO layer
to use GPIOLIB to allow the generic GPIO expanders and the like to
be compiled.
As a side-effect, we also remove __init_or_module from several
functions which could be called by drivers such as i2c-gpio which
could plausibly be compiled into a non-modular kernel.

People often point to the Integrator/Versatile/Realview
implementations to justify using the consumer name as the sole
selector for clocks.
Eliminate this excuse by changing the Versatile implementation, so
it provides a better example of how it should be done.
