From 967952a102f13825085fdab6e37738d437eca655 Mon Sep 17 00:00:00 2001 From: Patrick Georgi Date: Tue, 9 Feb 2010 19:41:11 +0000 Subject: Add image updating support. When selecting it, it expects a coreboot.rom to be available, and adds the files to it. It has no idea how to replace files, it merely adds them. It only works with Tinybootblock and the bootblock is immutable. The "clean" rules allow "make clean-for-update", which removes everything but coreboot.rom Signed-off-by: Patrick Georgi Acked-by: Peter Stuge git-svn-id: svn://svn.coreboot.org/coreboot/trunk@5103 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1 --- src/arch/i386/Kconfig | 10 ++++++++++ src/arch/i386/Makefile.tinybootblock.inc | 5 +++++ 2 files changed, 15 insertions(+) (limited to 'src/arch') diff --git a/src/arch/i386/Kconfig b/src/arch/i386/Kconfig index d64eb7f28e..bf60039f8f 100644 --- a/src/arch/i386/Kconfig +++ b/src/arch/i386/Kconfig @@ -49,6 +49,16 @@ config BIG_BOOTBLOCK default n if TINY_BOOTBLOCK default y +config UPDATE_IMAGE + bool "Update existing coreboot.rom image" + default n + depends on TINY_BOOTBLOCK + help + If this option is activate, no new coreboot.rom file + is created.
