A previous patch was introducing a SPARSEMEM dependency on
!HIGH_PHYS_OFFSET but it should actually be !REALVIEW_HIGH_PHYS_OFFSET.

The RealView PBX board has two 512MB blocks of memory - one at
0x70000000 (with 256MB mirror at 0) and another at 0x20000000. Only the
block at 0x70000000 (or the mirror at 0) may be used for DMA (e.g.
framebuffer). This patch adds the sparsemem definitions to allow the use
of all the memory split as follows:
256MB @ 0x00000000 (ZONE_DMA)
512MB @ 0x20000000 (ZONE_NORMAL)
256MB @ 0x80000000 (ZONE_NORMAL)

Kconfig entries default to n, so there's no need for this to be
explicitly specified.

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.

This is a RealView platform supporting core tiles with ARM11MPCore,
Cortex-A8 or Cortex-A9 (multicore) processors. It has support for MMC,
CompactFlash, PCI-E.

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.

This seems to be missing from the arm:devel branch, though the other
RealView configurations were modified accordingly.

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.

Rather than:
config CPU_BLAH
bool
depends on ARCH_FOO || MACH_BAR
default y if ARCH_FOO || MACH_BAR
arrange for ARCH_FOO and MACH_BAR to select CPU_BLAH directly.

By default, this option was selected by the platform Kconfig. This
patch adds "depends on" to L2X0 so that it can be enabled/disabled
manually.

The kernel originally supported revB only. This patch enables revC by
default and adds a config option for building the kernel for the revB
platform. Since the SCU base address was hard-coded in the proc-v6.S
file (and only valid for RealView/EB revB), this patch also adds a
more generic support for defining the SCU information.
