From 06c04299c1420fa94a1a53cc36c9d91a5e31a22a Mon Sep 17 00:00:00 2001 From: Patrick Georgi Date: Sat, 7 Jan 2012 19:15:43 +0100 Subject: Another indirection for normal/fallback bootblock Provide a way to redefine the names of normal and fallback via CBFS. This way updates can use some more expressive naming scheme (numbers, dates, version numbers) and replace the coreboot-stages file to point to the new version (with the current version as new "old"). If coreboot-stages doesn't exist, the default behaviour remains to use "normal" and "fallback".
