Re: [Qemu-devel] [Consult] microblaze: About running upstream main branch qemu

[Chen Gang]

OK, thanks, there are multiple branches in upstream qemu. Sorry
for my original said, and I can only say: for upstream  develop
master branch, it does not support microblaze.

Excuse me, I does not mainly focus on only using qemu, and I
also found another easier way for test microblaze toolchain (use sim of 
binutils). So next, I will mainly focus on sim.

I also met some issues for sim, but I guess, I can analyze it,
maybe also have chances to make patch for it (that is the main
reason why I want to focus on it).

Thanks.
