ee8c957119 RealView: Move the IRQ_* definitions out of the board-*.h files
The IRQ_* macros need to be made visible via the mach/irqs.h file but
without the additional macros defined in the board-*.h files.

af607747de RealView: Allow access to the secure flash memory block on PB1176
This patch adds a Kconfig option for specifying whether Linux will only
be run in secure mode on the RealView PB1176 platform. Enabling it will
make the secure flash memory block (64MB @ 0x3c000000) available to
Linux.

49613d4d9a [ARM] smp: SCU is used on non-realview platforms
The SCU can be used by non-realview platforms, so make it visible
for other people to use rather than having them copy the header file.

78d236c2b3 [ARM] realview: remove useless smp_cross_call_done()
smp_cross_call_done() is a no-op for MPCore, and since it's only
used by platform code, there's no point in having it unless it's
doing something.

be093beb60 [ARM] pass reboot command line to arch_reset()
OMAP wishes to pass state to the boot loader upon reboot in order to
instruct it whether to wait for USB-based reflashing or not.  There is
already a facility to do this via the reboot() syscall, except we ignore
the string passed to machine_restart().

This patch fixes things to pass this string to arch_reset().  This means
that we keep the reboot mode limited to telling the kernel _how_ to
perform the reboot which should be independent of what we request the
boot loader to do.

6be62ba215 [ARM] 5396/1: RealView: Use PATA_PLATFORM to access the CompactFlash
This driver adds the platform_device definitions to allow the use of
CompactFlash on the RealView PB11MPCore and PB-A8 platforms. Note that
the CompactFlash controller is expected to be initialised by the Boot
Monitor and support the True IDE mode.

ebac6546df RealView: Use only the shadow mapping of ARM11MPCore local timers

70bb62f8ec RealView: Allow PHYS_OFFSET at 0x70000000
RealView boards like PB11MPCore have 512MB of RAM available contiguously
at 0x70000000. Half of the memory is mirrored at 0x00000000 for
backwards compatibility. This patch adds the
CONFIG_REALVIEW_HIGH_PHYS_OFFSET option option to change the physical
base address so that the full amount of RAM is available to Linux. Note
that the EB board has 256MB of RAM also mirrored at 0x70000000, the only
board without this feature being PB1176.

dcea83adc6 [ARM] Hide ISA DMA API when ISA_DMA_API is unset
When ISA_DMA_API is unset, we're not implementing the ISA DMA API,
so there's no point in publishing the prototypes via asm/dma.h, nor
including the machine dependent parts of that API.

This allows us to remove a lot of mach/dma.h files which don't contain
any useful code.  Unfortunately though, some platforms put their own
private non-ISA definitions into mach/dma.h, so we leave these behind
and fix the appropriate #include statments.

b5ee900258 [ARM] remove a common set of __virt_to_bus definitions
Let's provide an overridable default instead of having every machine
class define __virt_to_bus and __bus_to_virt to the same thing.  What
most platforms are using is bus_addr == phys_addr so such is the default.

One exception is ebsa110 which has no DMA what so ever, so the actual
definition is not important except only for proper compilation.  Also
added a comment about the special footbridge bus translation.

Let's also remove comments alluding to set_dma_addr which is not
(and should not) be commonly used.

cf30fb4a4f [ARM] realview: convert to clkdev and lookup clocks by device name
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 Realview implementation, so
it provides a better example of how it should be done.

877d1f3389 RealView: Make more vmalloc space by changing IO_ADDRESS
Since boards like PB11MPCore have 512MB of RAM and 128MB of flash, the
virtual space is short on vmalloc memory and mapping the flash fails.
This patch changes the IO_ADDRESS so that static mappings start at
0xfc000000 and moves the PCI virtual addresses higher up. The new
VMALLOC_END is set to 0xf8000000 (512MB higher than the old value).

2c0aec814d RealView: Add debug-macro.S support for the PB1176 platform
The UART0 address is different on PB1176 from EB or PB11MPCore. This
patch adds the necessary #ifdef's to this file. The disadvantage is
that enabling CONFIG_DEBUG_LL will work properly on PB1176 if only
this platform is enabled.
