S5PC100 is a new SoC with ARM coretex-A8 and numerous peripherals. This SoC is
successor of S3C64XX. S5PC100 has peripherals which are still similar to S3C
families so some drivers in "arch/arm/plat-s3c" can be shared. S5PC100 specific
drivers will be added in "arch/arm/plat-s5pcxx" or "arch/arm/mach-s5pc100"

Starting with ARMv6, the CPUs support the BE-8 variant of big-endian
(byte-invariant). This patch adds the core support:
- setting of the BE-8 mode via the CPSR.E register for both kernel and
user threads
- big-endian page table walking
- REV used to rotate instructions read from memory during fault
processing as they are still little-endian format
- Kconfig and Makefile support for BE-8. The --be8 option must be passed
to the final linking stage to convert the instructions to
little-endian

"""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

The MSM architecture covers a wider family of chips than just the MSM7X00A.
Move to a more generic name, in perparation for supporting the specific
SoC variants as sub-architectures (ARCH_MSM7X01A, ARCH_MSM722X, etc). This
gives us ARCH_MSM for the (many) common peripherals.
This also removes the unused/obsolete config item MSM7X00A_IDLE.

Add minimal omap3430 support based on earlier patches from
Syed Mohammed Khasim. Also merge in omap34xx SRAM support
from Karthik Dasu and use consistent naming for sram init
functions.
Also do following changes that make 34xx support usable:
- Remove unused sram.c functions for 34xx
- Rename IRQ_SIR_IRQ to INTCPS_SIR_IRQ and define it locally
in entry-macro.S
- Update mach-omap2/io.c to support 2420, 2430, and 34xx
- Also merge in 34xx GPMC changes to add fields wr_access and
wr_data_mux_bus from Adrian Hunter
- Remove memory initialization call omap2_init_memory() until
until more generic memory initialization patches are posted.
It's OK to rely on bootloader initialization until then.
