Linus Walleij f022e4e41b ARM: 6986/1: mach-realview: add TCM support for PB1176
Enable TCM support on the RealView PB1176 - we have now taken
the precautions necessary to support even multi-board builds of
RealView systems with TCM enabled.

Russell King d2a1c9ad78 ARM: realview: name configuration options after actual board names
As no one seems to really know which configuration options tie up with
which boards, I thought I'd do some investigation and try to work it
out.  After discussion with some folk in linaro, I think I have this
nailed.

The names are updated to use the name on the front of the appropriate
board user guide for the various baseboards, which I've taken to be
the official name for each board.

I haven't significantly updated the descriptions for the tiles as that
is even less clear - as far as I can see on ARMs website, there is no
Cortex-A9 tile for Realview EB - only ARM11MPCore, ARM1156T2F-S,
ARM1176TZF-S and Cortex-R4F.  So exactly what this 'Multicore Cortex-A9
Tile' is...

Catalin Marinas 2503a5ecd8 ARM: 6201/1: RealView: Do not use outer_sync() on ARM11MPCore boards with L220
RealView boards with certain revisions of the L220 cache controller (ARM11*
processors only) may have issues (hardware deadlock) with the recent changes to
the mb() barrier implementation (DSB followed by an L2 cache sync). The patch
redefines the RealView ARM11MPCore mandatory barriers without the outer_sync()
call.

Catalin Marinas c97c5aa83c RealView: Add sparsemem support for the RealView PBX platform
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)

Catalin Marinas 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.

The kernel originally supported revB only. This patch enables revC by
default and adds a config option for building the kernel for the revB

file (and only valid for RealView/EB revB), this patch also adds a
more generic support for defining the SCU information.
