Version 2 of the sm501 changes with fixes that are needed to get
AmigaOS 4.1FE to boot and able to produce graphics.

The strange blue-white colors that first appear are actually correct
and because of AmigaOS selecting a low resolution PAL mode by default
instead of a board specific mode. To work around this one can select
the last option to boot the live CD and then select a better board
specific mode from ScreenMode Prefs. It takes a while for the
ScreenMode window to appear and graphics operations are slow which
could use some improvement but at least it seems to work correctly now
apart from some unimplemented drawing modes for compositing.

If this could be merged before the freeze with the sam460ex patches
and Sebastian's ehci patch then QEMU 3.0 could be the first version
that can boot AmigaOS.

Ping? Sorry to push it but it would be great if this could get in for 3.0. Peter, this may need your attention like last time as it's not clear whose tree it should go through and David did not seem to be confident taking it via the ppc tree.

Thank you,
