81cf5d7aae improve pcibus_check: Only assume PCI if at least one PCI to anything bridge
on bus 0.
This fixes problems with EISA-only systems mistakenly being assumed to support PCI.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

Bruce suggest removing the macros completely, but I'm not up to that
task quite yet.

9b2b0822b7 Removed unused #includes of <i386/isa/icu.h> and <i386/isa/icu.h>. icu.h
is only used by the icu support modules and by a few drivers that know
too much about the icu (most only use it to convert `n' to `IRQn').  isa.h
is only used by ioconf.c and by a few drivers that know too much about
isa addresses (a few have to, because config is deficient).

6ea3e9d839 Completed function declarations and/or added prototypes and/or added

pci now uses a different interrupt handler type for interrupts that it
dispatches and the isa interrupt handler type for the interrupts that
it handles.

0e2f699b9e At least the ASUS Triton motherboards don't disable the PCI bus configuration
accesses after the BIOS bus scan. The previous revision made the assumption,
that every PCI motherboard did ...

Change the test on the initial value of the CONF1_ADDR_PORT register in a way
that makes the probe succeed on triton based motherboards, without breaking
the EISA motherboard that has some non-PCI register at the same address.

287911bd50 Go back to separate tests for configuration mechanism 1 and mechanism 2.
Require the state of the configuration enable bits to be OFF assuming
that the BIOS left them that way, as it should anyway to avoid bad things
to happen.

The tests themselves are copied from the previous release, with the
exception of CONF1_ENABLE_MSK1 having the LSB set. This bit should be
read back as '0', since only DWORD addresses are legal.

a3adc4f8c5 Revert most changes of previous commit.
Changes relative to 1.12:

d33095d2b2 The physical memory allocated for input DMA must be contiguous. The driver
worked in the past only because of good fortune. Anyway, use the contig alloc
routine I wrote awhile ago (vm_page_alloc_contig) for the sound code to do
this allocation. Also, specify read+write on the permissions to pmap_enter().
Specifying just read can have unexpected consquences.

ether_input want it another way. Ripped out trailer support from the few

1) make #includes correct
2) fix bugs in address check macros
3) fixed bugs in, and enabled, recopy if heavily fragmented code
4) moved call to bpf tap to be before enqueing packet (probably gratuitous)
5) fixed bug that caused "abnormal interrupt" at boot time/first use
6) added support for reading Zynx address ROM
7) fixed bug that caused broadcasts to not work shortly after booting (only
	manifested if not using multicast - e.g. not in FreeBSD 2.0)
8) fixed spelling errors in comments
