[Qemu-ppc] PPC: VGA broken in git master

[Mark Cave-Ayland]

Hi all,

I've just done a git pull to update my local repository, and it now 
appears that the VGA device is broken in QEMU - rather than displaying 
the OpenBIOS banner in my VNC client, the framebuffer remains constantly 
black.

A git bisect shows that the problem is caused by the following commit:


de58ac72b6a062d1a61478284c0c0f8a0428613e is the first bad commit

    ioport: change portio_list not to use memory_region_set_offset()

    memory_region_set_offset() will be going away soon, so don't use it.
    Use an alias instead.

Avi/Richard - please would it be possible for you to review this commit 
and come up with a suitable fix?


Many thanks,

Mark.
