From b40bda6bd8b311d828a11dfa12df324cd51c3a55 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Thu, 16 Aug 2012 17:54:52 +0200 Subject: [PATCH] Makefile: Add possibility to set entry-point for u-boot.img This patch enabled boards using the SPL framework to set an entry point in the U-Boot mkimage image "u-boot.img". Until now the entry point in the header has been set to 0. By setting CONFIG_SYS_UBOOT_START in the board header, boards can override this default location. This will be used by the upcoming a3m071 MPC5200 board port.
