[U-Boot] [Patch 0/17] New 'qemu-mips64' test architecture for U-Boot
As so far, U-Boot has already supports mips32. But there are some differences between mips64 and mips32. Such as different ABI, different output format. so this patch adds mips64 support. I use cross compiler from clfs and build U-Boot like this: export CROSS_COMPILE=/home/zhangzz/work/clfs/sys_root/cross-tools/bin/mips64el-unknown-linux-gnu- make qemu_mips64_config make And run U-Boot with command below: $ qemu-system-mips64el -M mips -cpu MIPS64R2-generic -kernel u-boot -nographic U-Boot 2012.07-00089-gbbffc64 (Aug 14 2012 - 22:34:02)
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 #
===== Detail: 1 Add qemu_mips64_defconfig, and add related build configuration. 2 mips/cpu/mips64/* are derived from mips/cpu/mips32, but mips32 is using ABI O32, we can't build it with mips64 cross compiler. so changes are made. 3 Some address operation didn't take care about mips64, so asm/addrspace.h and io.h were changed.

many of your patches are line wrapped. please use `git send-email` rather than whatever client you're using (looks like gmail?) as it won't screw things up. -mike

hmm, actually it's worse than that -- the leading whitespace is all mangled too. i'm assuming your code isn't that screwed up, so please resend with git- sendemail. -mike

OK, I will retry. actually I sent it by copy-and-paste. I wasn't aware of that. thanks.

then you should read http://www.denx.de/wiki/U-Boot/Patches
And please do for all MIPS specific patches: - CC me - use the prefix MIPS: in the email subject

Thanks for all your suggestions. I will improve them in next version.
