[U-Boot] [Patch V4 3/4] MIPS: add board qemu-mips64 support

Zhizhou Zhang etou.zh at gmail.com
Mon Aug 27 14:49:04 CEST 2012


Both big-endian and little-endian are tested with below commands:
qemu-system-mips64el -M mips -cpu MIPS64R2-generic -kernel u-boot -nographic
qemu-system-mips64 -M mips -cpu MIPS64R2-generic -kernel u-boot -nographic
