I would move the definition of HAS_MEM_ACCESS from arch/*/Rules.mk to
config/*.mk and use the defition here to build or not xen-access.

ARM may contains multiple banks non-contiguous banks. On Xen 4.5, there
is 2 banks with a hole (see GUEST_RAM{0,1}_* in
xen/include/public/arch-arm.h).
This change won't work with guest using more than 3G of RAM.
