From b432b4b3440a34c1430fcd66bab783640724bd28 Mon Sep 17 00:00:00 2001 From: kishore kadiyala Date: Wed, 17 Nov 2010 22:35:32 -0500 Subject: [PATCH] mmc: omap4: hsmmc: Fix improper card detection while booting While booting OMAP4 ES2.0 boards, cards on MMC1 and MMC2 controllers are not getting detected sometimes. During reset of command/data line, wrong pointer to base address was passed while read operation to SYSCTL register, thus impacting the updated reset logic. Passing the correct base address fixes the issue.
