This is v2 patch set to support numa on arm64 based platforms.
Tested these patches on cavium's multinode(2 node topology) simulator.
In this patchset, defined and implemented dt bindings for numa mapping for core and memory.
Tested using UEFI which passes multi memory range details through UEFI system
table. Tried test-cases present in numactl-2.0.9 package.
v2:
Defined and implemented numa map for memory, cores to node and
proximity distance matrix of nodes to each other.
v1:
Initial patchset to support numa on arm64 platforms.
