From 69cb2c2b5e4c4e4db005dc57249c0d15cadea5ee Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Tue, 21 Apr 2015 15:18:22 -0500 Subject: coreboot: add a place to choose romstage loader Instead of always loading romstage from cbfs provide a way, similar to ramstage and payload, for other program loaders to intervene. For now, only the cbfs loader is consulted.
