commit ba4dcdadb050d3f0425f847842a8e24d0ba8f8bd Author: Duncan Laurie dlaurie@chromium.org Date: Wed Oct 2 16:10:54 2013 -0700
samus: Add coreboot board
Add the coreboot board files for samus - Based on Bolt - GPIO setup based on 0.91 schematic - Support both memory types - No HDA verb table for this platform - Some GPIO interrupts are shared and need to be passed to OS
