augustss 526ef2f618 Change the interface between the high and low level audio drivers 
so that all audio encoding parameters are set at once.  This simplifies
the interface and make error checking easier.

mrg bb07095632 as per discussion with torek, allow TC=1. also add option 
to allow TC=0.  the zilog documentation says not to allow
TC=0 -- however, i tested this and it "does work", as far
as i could tell, so, allow this use if so desired.

is 07b064e02e 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.

abrown 19b3f7f50b Initial commit of cg14 framebuffer driver for Sun4m SPARCs. 
- This driver supports the on-board mbus-based cgfourteen (sometimes referred
  to as "SX") video hardware present on SS20-class machines.
- It does *not* support any of the SX acceleration features.
- It does support the 8-bit mode of the hardware, and looks to X like
  a cgthree.
- It does support the cg6-style hardware cursor, even when running X in
  cgthree emulation.
- It does support DPMS power-down of compatible displays on later-revision
  cg14's.
- There is code to support the true color (32-bit) mode of the cg14 as
  cg8 emulation, but it is disabled by default because it is most likely
  broken. #define CG14_CG8 to turn it on.

The driver is not yet installed in the conf files, but I will do so
shortly...

NOTE: THESE FILES ARE NOW IDENTICAL TO THEIR ALPHA COUNTERPARTS.

easier way to do this than I had planned...

abrown 0c6696de2d Take advantage of new am7990 sc_nocarrier() function in order to do auto- 
matic media detection on Sun4m machines which support multiple media
(UTP and AUI). New function lenocarrier() switches media type when called
if no link? flags are set.

Redefine link flags for Lance ethernet (le):
	<none>:	switch between media as needed to find carrier (autodetect)
		Preference to whatever the PROM is using (AUI if not booted
		from the network)
	link0:	use UTP port only
	link1:	use AUI port only

This allows Sun4m machines with dual media Lance ethernet adapters to
boot from the network on the UTP port.
