*	MIPS: Loongson: Naming style cleanup and rework	Huacai Chen	2015-06-21	1	-53/+0
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Currently, code of Loongson-2/3 is under loongson directory and code of Loongson-1 is under loongson1 directory. Besides, there are Kconfig options such as MACH_LOONGSON and MACH_LOONGSON1. This naming style is very ugly and confusing. Since Loongson-2/3 are both 64-bit general- purpose CPU while Loongson-1 is 32-bit SoC, we rename both file names and Kconfig symbols from loongson/loongson1 to loongson64/loongson32.

*	MIPS: Add NUMA support for Loongson-3	Huacai Chen	2014-07-30	1	-0/+53
	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.
