From 26883c699eee60c6f2dd63818a9dd470f2c567fc Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Mon, 21 Feb 2011 20:57:53 +0000 Subject: hw/realview: Wire up the MMC card status Instantiate the three PL061 GPIO modules the realview boards have. Connect the MMC card status outputs of the PL181 MMC controller to both the system registers and the GPIO module which handles internal devices.
