commit f22419b242a6d28bcbdfaaa524bba87348f29e9d Author: Kyösti Mälkki kyosti.malkki@gmail.com Date: Thu Feb 27 19:30:18 2014 +0200
console: Use romstage code for ramstage and SMM
Console is arch-agnostic and there is no need for separate implementations for romstage and ramstage.
For SMM there is console only if DEBUG_SMI is selected.
