From 6385b28116f775da4771b768ba9bf93c3aaaf26e Mon Sep 17 00:00:00 2001 From: Peter Tyser Date: Mon, 21 Sep 2009 11:20:32 -0500 Subject: fpga: Remove relocation fixups PPC boards are the only users of the current FPGA code which is littered with manual relocation fixups. Now that proper relocation is supported for PPC boards, remove FPGA manual relocation.
