Making SMP depend on (huge list of MACH_ and ARCH_ configs) is
bothersome to maintain and likely to lead to merge conflicts.
This patch moves the knowledge of which platforms are SMP-capable
to the individual machines. To enable this, a new HAVE_SMP config
option is introduced to allow machines to indicate that they can
run in a SMP configuration.

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.
