From cd227fbffa9e971ee80065de772d3201c73e1670 Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Wed, 17 Aug 2011 14:23:46 +0100 Subject: [PATCH] ARM: 7021/1: Check for multiple load addresses before building a uImage uImages need a load address specified. This makes them incompatible with multiple zreladdrs. Catch this error before building an uImage so that we do not end up with broken uImages. The load address can still be specified with LOADADDR= on the command line.
