qemu: add 800D to model_list.c, and add 800D/debugmsg.gdb
Created originally on Bitbucket by ids1024 (Ian Scott)
Was already merged in Bitbucket before import, marked as merged by the import user
I’m not 100% sure all the stubs are correct, but I thought it would be better to PR than just leave it sitting on my computer. This seems to make some of the qemu/gdb debugging functionality work.
