Huacai Chen c461731836 MIPS: Add NUMA support for Loongson-3 ... Multiple Loongson-3A chips can be interconnected with HT0-bus. This is a CC-NUMA system that every chip (node) has its own local memory and cache coherency is maintained by hardware. The 64-bit physical memory address format is as follows: 0x-0000-YZZZ-ZZZZ-ZZZZ The high 16 bits should be 0, which means the real physical address supported by Loongson-3 is 48-bit. The "Y" bits is the base address of each node, which can be also considered as the node-id. The "Z" bits is the address offset within a node, which means every node has a 44 bits address space. Macros XPHYSADDR and MAX_PHYSMEM_BITS are modified unconditionally, because many other MIPS CPUs have also extended their address spaces.
