From 2c08ea7cfcb24240e41ad0f75be35f9e2967b3d1 Mon Sep 17 00:00:00 2001 From: Joe Moore Date: Mon, 21 Oct 2019 01:03:08 -0600 Subject: cpu/nb/sb: Remove fam12 With removal of Torpedo mainboard, this code is no longer necessary. This also removes fam12 support from northbridge and SB900 from southbridge.
