This is a rework of Cormac O'Brien's GSoC project to try and boot MacOS 9 under QEMU, the original version of which was posted to the qemu-devel list at the end of August (https://lists.gnu.org/archive/html/qemu-devel/2015-08/msg02521.html).
The patchset consisted of some simple patches from Alex and then a large set of CUDA changes supplied as a single patch which were the result of Cormac analysing MOL with Alex's help to try and further the boot process. In their previous form, the patches were unsuitable for applying upstream since while they furthered MacOS 9 boot, they also caused a couple of major regressions such as breaking the mouse and causing Darwin/OS X boot to panic on startup. This reworked patchset fixes these regressions, includes some other clean-ups and more importantly now passes all of my OpenBIOS image boot tests with an OpenBIOS binary from SVN trunk (separate pull request to be sent shortly). Whilst OpenBIOS still needs one additional patch to run the MacOS 9 bootloader, I've uploaded a pre-compiled binary to https://www.ilande.co.uk/tmp/openbios-ppc for people interested in testing the new MacOS 9 functionality.
