[Qemu-devel] [FYI] sh: QEMU-SH patch list

[Shin-ichiro KAWASAKI]

Hi, all.

I've made a list for those who interested in SuperH emulation by QEMU.
These are patches related to SH emulation and not yet merged into the trunk.
Some of them need review, and some of them need brushing up.
I hope this list encourages cross review.

Please tell me any mistakes, problems, or something to add.

Regards,
Shin-ichiro KAWASAKI
