Remove FDDI support.

merge ktrace-lwp.

add centralized {eisa,isa,pci,agp,mca}busprint() functions which do
what tens of the bus' parents foo{...}bridge_print()s scattered around do

branches: 1.25.16;
- convert usage of "defopt" to "defflag" where the relevant option does
not support a value (e.g., it's to be used as "options FOO" instead of
"options FOO=xxx"). options that take a value were converted to
defparam recently.
- minor whitespace & formatting cleanups

branches: 1.24.2;
Add an (untested) EISA front-end for the `mlx' driver.

branches: 1.23.2;
whitespace police

Add an EISA bus front-end for the `cac' driver.

Add support for the DEC DE422 Ethernet, which is a DEPCA
attached to the EISA bus. This board is commonly found
on Alpha Jensen systems.

branches: 1.20.4;
Update EISA frontend for new ahc driver (done by Noriyuki Soda).

branches: 1.19.2;
EISA frontend for DPT driver (as yet untested).

EISA bus front-end for the New Tulip Driver, for the DEC DE425 EISA
board. The DE425 is basically a DECchip 21040 on an EISA board, plus
a Cool Address Decoder Hack which maps the PCI configuration
space registers into EISA I/O space, interleaved with the Tulip CSRs,
which are spaced further apart than on the PCI versoin.

This is currently *untested* until the DE425 boards that folks have
promised me arrive. But, it should work, since the 21040 works.

branches: 1.17.8;
Remove "class" declarations, and add "devclass" declarations where
appropriate. Fix several inconsistencies between device class and
attributes. Mostly from Chris Demetriou.

Add device classes.

Declare EISAVERBOSE by defopt in files.eisa. Include opt_eisaverbose.h
in eisa.c.

branches: 1.14.2;
config.new => config

New ARP system, supports IPv4 over any hardware link.

Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.

For the detailed change history, look at the commit log entries for
the is-newarp branch.

branches: 1.12.6;
Update.

disable AHA-284x product ID, because it is now handled by ahc_isa.c.

branches: 1.10.4;
Add the DEFEA FDDI controller.

New version, with changes from Justin Gibbs and Noriyuki Soda.

Break up the ep driver into isa, eisa, and pci front-ends and a
bus-independent core driver. Tested on all three bus types, including
an isa 3c509 masquerading as an eisa device (use ep* at eisa? slot ? in
your kernel config file to catch this one).
XXX Driver still needs to be converted to <machine/bus.h>

New device attachment scheme:

- split softc size and match/attach out from cfdriver into
a new struct cfattach.

- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached
to parents with different autoconfiguration semantics.

the i386 port no longer attaches isa, eisa, and pci at root.

add a comment (XXX) about eisa's attachment.

eisabus attribute moved to conf/files

Better EISA autoconfiguration, per PR 1959.

try to actually (gasp!) describe the drivers.
