From 244615197469dd6fe75ae082f38424b97c79aeaf Mon Sep 17 00:00:00 2001 From: Peter Tyser Date: Mon, 21 Sep 2009 11:20:26 -0500 Subject: [PATCH] ppc: Check for compilers that don't support relocation Certain ppc compilers are known not to generate the .fixup section properly. The .fixup section is necessary to create a relocatable U-Boot image. A basic check for the existence of the .fixup section should hopefully catch the majority of broken compilers which don't support relocation.
