[PATCH 3/3] ARM: Allow either FLATMEM or SPARSEMEM on the multi-v7 build

[Kevin Cernekee]

ARMv7 chips with LPAE can often benefit from SPARSEMEM, as portions of
system memory can be located deep in the 36-bit address space.  Allow
FLATMEM or SPARSEMEM to be selectable at compile time; FLATMEM remains
the default.
