I quite agree.
I have just got a copy of the MC68030 User's manual, and I'm about to learn
all about interrupts and exceptions ;-S
Does anyone (appeal...) know of any documentation on VIA2 or (even better) RBV?
And no, /sys/arch/mac68k/mac68k/via.[ch] is not a good enough answer ;-)
If we are to use the slot manager stuff, that means more MRG, doesn't it?
Urghh...
