From 8d33b05581d1bc66e2356957bb2739e177a9cc36 Mon Sep 17 00:00:00 2001 From: Bridge Wu Date: Fri, 21 Dec 2007 19:15:36 +0800 Subject: [PATCH] [ARM] pxa: mmc: add 2nd host controller support for pxa3xx This patch is to add the second mmc controller support for pxa3xx. It's valid for pxa3[0|1|2]0. On zylonite, the second controller has no slot.
