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)

help
RealView boards other than PB1176 have the RAM available at
0x70000000, 256MB of which being mirrored at 0x00000000. If
the board supports 512MB of RAM, this option allows the
memory to be accessed contiguously at the high physical
offset. On the PBX board, disabling this option allows 1GB of
RAM to be used with SPARSEMEM.
