From f1d2b313c9eb6808d30c16a9eb5251240452a56c Mon Sep 17 00:00:00 2001 From: Heiko Schocher Date: Fri, 17 Sep 2010 13:10:39 +0200 Subject: ARM: add relocation support !! This breaks support for all arm boards !! To compile in old style, you must define CONFIG_SYS_ARM_WITHOUT_RELOC or you can compile with "CONFIG_SYS_ARM_WITHOUT_RELOC=1 ./MAKEALL board" !! This define will be removed soon, so convert your board to use relocation support Portions of this work were supported by funding from the CE Linux Forum.
