[Qemu-devel] sparc sun4m changes

[Robert Reif]

I just took a look at the sun4m interrupt controller and noticed
the recent changes.  There are at least 3 different interrupt
controllers used by sun4m: ss600mp with VME and MBUS
specific support, ss 10/20 with MBUS support and ss 4/5/lx
with slavio support.  This doesn't even address the java stations.

intbit_to_level in slavio_intctrl.c needs to be different for each
controller chip used.  There also needs to be a controller specific
interrupt mask used.

The NCR slavio chip is only used for single processor systems
(ss 4/5/lx).  It is a subset of the ss 10/20 which is a subset of the
ss600mp.  We really should address these differences.
