This patch add mips64 cpu support. In this version, I have tested it both when configured running in ram version and running in rom version.

Board: Qemu -M mips CPU: unknown proc_id=0x10000 DRAM: 128 MiB Using default environment
In: serial Out: serial Err: serial Net: NE2000 qemu-mips64 #
Changes in V5: - omit camel-case style - avoid running "git bisect" failed - some code style problem corrected Changes in V4: - Add both big-endian and little-endian support - Remove cache probe - Add standalone support for mips64 Changes in V3: - merge related files into one patch, no longer one file one patch. - add detailed commit message. - remove standalone example. it's too complicate.
Zhizhou Zhang (4): MIPS: Don't use camel-case style MIPS: change address related header files MIPS: don't define CONFIG_SYS_TEXT_BASE in config.mk MIPS: add board qemu-mips64 support
