From 84be0f59b7158d5d60e1d7d61786d0a6e449d682 Mon Sep 17 00:00:00 2001 From: Nils Jacobs Date: Wed, 29 Dec 2010 21:12:10 +0000 Subject: -Change the remaining GLIU1 port 5 register names from VIP (Video Input Port) to FG (FooGlue). As the GX2 has no VIP port. -Change the Memmory setup MSR register names so they correspond better to the databook. (Part1) This is less confusing for beginners. -Add a MSR printing function to northbridge.c like in the Geode LX code. -Remove the AES register names.(GX2 has no AES registers) -Delete some unused code. -Clean up GX2 northbridge code to match Geode LX code. -Add missing copyright header to northbridge.c. -Move hardcoded IRQ defining from northbridge.c to irq_tables.c .
