From aba27acf6711dce0ef1507f2f9f02a80d70a45da Mon Sep 17 00:00:00 2001 From: Dirk Eibach Date: Wed, 26 Jun 2013 16:04:26 +0200 Subject: powerpc/ppc4xx: Use generic accessor functions for gdsys FPGA A set of accessor functions was added to be able to access not only memory mapped FPGA in a generic way. Thanks to Wolfgang Denk for getting this sorted properly.
