From c5ed53687b39c195b4730de8c0355c1b78054ba6 Mon Sep 17 00:00:00 2001 From: Yoshihiro Shimoda Date: Mon, 7 Mar 2011 21:59:38 +0000 Subject: [PATCH] net: sh_eth: remove almost #ifdef of SH7763 The SH7763 has GETHER. So the specification of some registers differs than other CPUs. This patch removes almost #ifdef of CONFIG_CPU_SUBTYPE_SH7763. Then we are able to add other CPU's GETHER easily.
