Define a `vme' device on `iommu' and allow `vmes' and `vmel' as sub-busses.

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

add emul.c

specs for ISP 10x0 (isp) driver Sbus attachment. From Matt Jacob.

esp carries ncr53c9x attribute

"md" is declared in sys/conf/files, now.

rename: ramdisk => md

Declare lebuffer

Centralize the declaration of the "en" driver (Efficient Networks, Inc.
155Mb/sec ATM interface).

Declare device `audio' at sbus where it resides on Microsparc machines,
from Nick Sayer's PR#2908.

Add cgfourteen driver as device "cgfourteen"

sbus specific stuff for eni155s sbus atm card.
XXX: only works on sun4c, needs something better than vtophys() for
machines with IOMMUs(?).

`rd_root.c' => `md_root.c'

ramdisk stuff.

Add tcx definition.

Switch to `sys/dev/sun/event.c'.

Remove the `espdma' special case; all `esp' related dma channels are now
called `dma' on all architectures. Note: `ledma' remains in place.

Also delete a couple of unneeded `needs-flag's in files.s

Change attributes of `dma', `espdma' and `ledma' (the attributes on the latter
two didn't seem to make much sense anyway..) to allow `esp' devices to be
attached to one of `sbus', `dma' and `espdma'.

Change attributes of `dma', `espdma' and `ledma' (the attributes on the latter
two didn't seem to make much sense anyway..) to allow `esp' devices to be
attached to one of `sbus', `dma' and `espdma'.

Remove the wildcarded `espdma?' and `ledma?' attachments of `esp' and `le'
respectively, in favour of `dma?' and `lebuffer?' (but the latter is not
yet implemented), which seems to better match reality: additional SBus
SCSI/Lance boards call themselves `dma' and `lebuffer'.

Make the MI LANCE driver standalone, and use cfattach to resolve
naming conflicts between bus attachments on ports that can have
multiple instances of the LANCE.

If the power device is configured, don't forget to compile the driver.
Also, add some whitespace for readability.

Include fd.c if (fdc | fd), so we're not obliged to define a device
at fdc.

sun4m device definitions and bus structure.

adjust to deal with expression support for optional file specs

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 s

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.
