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.

I can have a look, but really I think these should go via the
ppc tree -- the device is used in a ppc machine and an sh4 one,
and the ppc tree is much more active than sh4.

Thank you. Please agree on what should be the needed action here. It would be a pity if this missed 3.0 because of this. Could it be merged before the freeze if no obvious problems are found with that it can be removed later if it causes any trouble (I think that's unlikely as it's only touches rarely used parts).
