Log:
Move to using a chip function + function pointers to deal with the
function and csc interrupt routing path (eg, ISA or PCI) so that we
can more easily switch between the two.
When we don't have a card ISR, put the function interrupt into ISA
mode. This effectively masks the interrupt since it happens once, and
not again until we have an ISR. This should help hangs, and might
help people that unwisely update the kernel w/o updating pccardd.
This is done at mapirq time.
Force CL-PD6729/30 to use ISA interrupt routing and maybe even detect
the number of pccard slots properly (this is still WIP). We aren't
going to support PCI interrupts for this release. A future release
should support them, however. Shibata-san's 3.3V fixes are not
included.
Add a hack which should, in i386, rewrite IRQ 0 cardbus bridges to be
IRQ 255, which should cause interrupts to be routed. This is mostly
untested since my one tester disappeared after reporting nothing
changed.
Implement, but do not use, a power method called cardbus. It looked
like a great way to get around the 3.3V problem, but it seems that you
can only use it to power cardbus cards (I get no CIS when I enable it,
so maybe we're programming things bogusly).
GC the intr and argp stuff from the slot database.
Improve the ToPIC support with the power hacks that Nakagawa-san
published in FreeBSD Press and that Hiroyuki Aizu-san ported to
-stable. The ToPIC hacks were for 3.3V support in ToPIC 100, but it
looks like the '97 also has identical registers, so use them too.
Add some #defines for the cardbus power stuff.
Finally implement making CSC on the Ricoh chips ISA or PCI. This will
allow polling mode to work on vaios, I think.
Add some minor debugging. This should likely be cleaned up or put
behing a bootverbose.
Some of this work, and earlier work, was influanced by Chiharu
Shibata-san's power handing patches posted to bsd-nomads:15866.
MFC: Soon, if possible.
