[Qemu-devel] [PATCH 0/5] PPC: Mac99 emulation fixes

[Alexander Graf <agraf@suse.de>]

While trying to get Mac OS X booting with our -M mac99 emulation I stumbled
over a few issues that prevented it from doing so.

With these patches applied I still can't properly boot Mac OS X with -M mac99,
but I get a lot further than before. The biggest issue that's left now is to
properly fake Mac OS X into believing our timebase frequency. If I hack up the
cuda timer I can successfully boot Mac OS X on mac99:

 /* CUDA returns time_t's offset from Jan 1, 1904, not 1970 */

Please bear in mind that this patch set depends on an OpenBIOS update.
