From ac2785c63ed47123fbefa60b6a6c38029b1c2ed5 Mon Sep 17 00:00:00 2001 From: Po Liu Date: Wed, 21 Aug 2013 14:22:18 +0800 Subject: [PATCH] powerpc:c29xpcie: make ifc timing parameter flexible This patch re-config the NOR flash timing parameters which could make the ifc timing more flexible for NOR flash. The new parameters could fix the problem of hanging at "Flash:" occasionally when booting the board.
