From 4c2245eb67b0eabf18fc9b6788bc05d962ef5e0e Mon Sep 17 00:00:00 2001 From: David Hendricks Date: Wed, 2 Jan 2013 17:41:51 -0800 Subject: [PATCH] snow: Stuff to support building image with BL1 This patch does two things which will take effect in follow-up patches: 1. Add an intermediate Makefile rule for dd'ing BL1 into the coreboot.rom pre-image. This is modeled after a similar hack for the bd82x6x southbridge. 2. Add a Kconfig variable, BOOTBLOCK_OFFSET, which will be used to pass the bootblock offset into cbfstool.
