[src/trunk]: src/sys/arch/atari Add support for the SMC Elite Ultra Ethernet ...
details: https://anonhg.NetBSD.org/src/rev/b7cdbd5fa95f
branches: trunk
changeset: 752980:b7cdbd5fa95f
user: tsutsui <tsutsui%NetBSD.org@localhost>

description:
Add support for the SMC Elite Ultra Ethernet with the SMC_TT VME-ISA bridge.
The SMC_TT is the user designed "handmade" VME-ISA bridge circuit
for 16 bit VME slot on TT030 and the SMC Elite Ultra ISA Ethernet card.
More information about SMC_TT can be found in the following archive:
ftp://ftp.funet.fi/pub/atari/net/smc_tt1.zip
Demonstrated on the NetBSD booth in Open Source Conference 2010 Kansai@Kobe.
