commit 3060582c2f767b79711b98e65d7ecebede52cd1f Author: Edward O'Callaghan eocallaghan@alterapraxis.com Date: Mon Jun 2 12:20:11 2014 +1000
superio/smsc/kbc1100: Virtually rewrite support and fix mainboards
1. Remove #include .c in romstage. 2. Make romstage component symbols linker-time. 3. Provide header guards and prototypes in superio romstage support. 4. Correct function type-signatures to be static/non-static where appropriate, avoid 'pretend optimisations' by unnecessarily inlining functions. 5. Separate out UART enable from various other PNP hard coding
