o Properly use rman(9) to manage resources. This eliminates the
need to puc-specific hacks to rman. It also allows devinfo(8)
to be used to find out the specific assignment of resources to
serial/parallel ports.
o Compress the PCI device "database" by optimizing for the common
case and to use a procedural interface to handle the exceptions.
The procedural interface also generalizes the need to setup the
hardware (program chipsets, program clock frequencies).
o Eliminate the need for PUC_FASTINTR. Serdev devices are fast by
default and non-serdev devices are handled by the bus.
o Use the serdev I/F to collect interrupt status and to handle
interrupts across ports in priority order.
o Sync the PCI device configuration to include devices found in
NetBSD and not yet merged to FreeBSD.
o Add support for Quatech 2, 4 and 8 port UARTs.
o Add support for a couple dozen Timedia serial cards as found
in Linux.
o Use __FBSDID2006-04-26T21:25:13ZMarcel Moolenaarmarcel@FreeBSD.org2006-04-26T21:25:13Zurn:sha1:df5fea7cad645fae5be20f01d77e303eca712b75
o Whitespace fixes
o Non-K&R functions
o Move ISA specific code from ppc.c to ppc_isa.c -- a bus front-2006-04-24T23:31:51ZMarcel Moolenaarmarcel@FreeBSD.org2006-04-24T23:31:51Zurn:sha1:cea4d8752f992568969c4078c519f0fdc94fe819
end for isa(4).
o Add a seperate bus frontend for acpi(4) and allow ISA DMA for
it when ISA is configured in the kernel. This allows acpi(4)
attachments in non-ISA configurations, as is possible for ia64.
o Add a seperate bus frontend for pci(4) and detect known single
port parallel cards.
o Merge PC98 specific changes under pc98/cbus into the MI driver.
The changes are minor enough for conditional compilation and
in this form invites better abstraction.
o Have ppc(4) usabled on all platforms, now that ISA specifics
are untangled enough.

- Move isa/ppc* to sys/dev/ppc (repo-copy)
- Add an attachment method to ppc for puc
- In puc we need to walk the chain of parents.
Still to do, is to make ppc(4) & puc(4) work on other platforms. Testers
wanted.
