From 17d667b411685de57ea181cc496b29fea6d27d91 Mon Sep 17 00:00:00 2001 From: Uwe Hermann Date: Tue, 3 Apr 2007 10:45:53 +0000 Subject: Add initial framework for the Tyan S1846. It's not fully working, among other things because the Intel 440BX northbridge isn't working, yet. Signed-off-by: Uwe Hermann Acked-by: Ronald G.
