The former consolidates the operations of if_attach(), ng_ether_attach(),
and bpfattach(). The latter consolidates the corresponding detach operations.

hose are 16 PCI instances apart. This allows us to recognize secondary
PCI busses (at least to a first level) until the pci infrastructure is
fixed.
Turn on support for secondary cycles, too. Redo debug printouts.
Instead, for now (until we get a pci infrastructure cleanup),
assign the PCI bus number to be mcpcia bus instance << 4. This
is to allow secondary bridges some room to be recongnized on
4100 systems.
SYSCTL_LONG macro to be consistent with other integer sysctl variables
and require an initial value instead of assuming 0. Update several
sysctl variables to use the unsigned types.

irongate chipset (used in the UP1000) which does not support scatter/gather
DMA. We'll still use scatter gather if the core logic chipset supports it.

fields, not lex/yacc grammar so it is not an exact match but should be
close enough for most cases.
Deal with 'port?', 'irq?' style specifications. These are parsed as
seperate values in lex/yacc in config(8) but tripped up this helper tool.
deal with filename arguments. It is amazing how much you forget over time.
Thanks to the people that reminded me this. I knew there was an easy way
that didn't involve messing with $argv, filehandles, etc, but just could
not remember - all of my books are on the opposite side of the planet..
Use Warner Losh's "hint" driver to decode ascii strings to fill the
resource table at boot time.
config(8) no longer generates an ioconf.c table - ie: the configuration
no longer has to be compiled into the kernel. You can reconfigure your
isa devices with the likes of this at loader(8) time:
set hint.ed.0.port=0x320
userconfig will be rewritten to use this style interface one day and will
move to /boot/userconfig.4th or something like that.
It is still possible to statically compile in a set of hints into a kernel
if you do not wish to use loader(8). See the "hints" directive in GENERIC
as an example.
All device wiring has been moved out of config(8). There is a set of
helper scripts (see i386/conf/gethints.pl, and the same for alpha and pc98)
that extract the 'at isa? port foo irq bar' from the old files and produces
a hints file. If you install this file as /boot/device.hints (and update
/boot/defaults/loader.conf - You can do a build/install in sys/boot) then
loader will load it automatically for you. You can also compile in the
hints directly with: hints "device.hints" as well.
There are a few things that I'm not too happy with yet. Under this scheme,
things like LINT would no longer be useful as "documentation" of settings.
I have renamed this file to 'NOTES' and stored the example hints strings
in it. However... this is not something that config(8) understands, so
there is a script that extracts the build-specific data from the
documentation file (NOTES) to produce a LINT that can be config'ed and
built. A stack of man4 pages will need updating. :-/
Also, since there is no longer a difference between 'device' and
'pseudo-device' I collapsed the two together, and the resulting 'device'
takes a 'number of units' for devices that still have it statically
allocated. eg: 'device fe 4' will compile the fe driver with NFE set
to 4. You can then set hints for 4 units (0 - 3). Also note that
'device fe0' will be interpreted as "zero units of 'fe'" which would be
bad, so there is a config warning for this. This is only needed for
old drivers that still have static limits on numbers of units.
All the statically limited drivers that I could find were marked.
Please exercise EXTREME CAUTION when transitioning!

loader for alpha (Yay!) we still need to explicitly look for boot_verbose-
I assume because the boothowto flags aren't passed to us at boot like x86.
Do some minor cosmetics as well.
Only PCI and on-board ISA peripherials are supported at this time.
This support has been only lightly tested due to a lack of response to my
call for testers on the freebsd-alpha mailing list. It works quite well
on the one AS2100 on which it has been tested, but it may not work on
an AS2100A and should therefore be regarded as experimental.
