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. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>

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.
