From 84a08fa9eb330969b661305bd5a5fcae06d98cba Mon Sep 17 00:00:00 2001 From: Jens Taprogge Date: Thu, 27 Sep 2012 12:37:29 +0200 Subject: [PATCH] Staging: ipack/bridges/tpci200: Store beginning of module memory regions in struct tpci200. tpci200_register is converted to use this. A later patch will build on this.
