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.

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.
