assume that the address we have is the correct PA if we can't
figure it out by groveling. This time it really (yes, really)
works on the PowerBook 14x/16x/170.
tctrl now initializes the state of the internal LCD icons. The icons
are unprogrammed at boot time. This incidentally makes the DC-POWER icon
work.
Fixes:
Fix my stupidity in the ENVSYS stuff, and actually follow the API.
This one is more in the spirit of incorrect version which was trying
to shorten the interrupt path. This probably isn't quite as fast as
using a switch() statement to dispatch the interrupts, but should be
a little faster than testing for each of the possible 6 interrupt
conditions.
than one interrupt bit is set (unless you do some fancy case values).
Check each interrupt bit individually and process the interrupt if set.
5000/200 doesn't hang shortly after booting now.
funk when they misbehave and give us unexpected results. Specifically:
- Don't assume that the first free slot is at the top of the table if
we can't find one.
- Don't increment ADBNumDevices when backfilling "holes" left by devices
that didn't respond to a TALK R3 during the initial device scan.
- Don't assume that an address reassignment worked; make sure something
responds on the new address before plowing forward.
- If after device reassignment there are no free slots, make sure to
indicate this fact.
- Failing all else, handle the situation where we run out of slots in
the device table -- which now should "never" happen -- gracefully.
While the Power Manager driver still sometimes misbehaves, it shouldn't
cause the system to crash/hang due to us walking off the end of the
device table.

IOASIC with both old and MI SCSI, on the 5000/25 PMAZ TC option card
with both old and MI SCSI, and with tftp boot on the 5000/25.
