From bdf913ab010c99db8e64845f5b5837c9008609dc Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Mon, 24 Feb 2014 14:56:34 -0600 Subject: coreboot: unify infrastructure for loading payloads A payload can be loaded either from a vboot region or from cbfs. Provide a common place for choosing where the payload is loaded from. Additionally, place the logic in the 'loaders' directory similarly to the ramstage loader infrastructure.
