From 3bd8437dcce211bba51b306a9b71f9eec4a474c2 Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Fri, 18 Nov 2011 12:48:01 +0000 Subject: [PATCH] OMAP3: Change mem_ok to clear again after reading back It's possible to need to call this function on the same banks multiple times so we want to be sure that 'pos A' is cleared out again at the end.
