Subject: [U-Boot] [PATCH v1 1/2] am33xx: enable GPMC clocks for TI814x
Date: Tue, 6 Aug 2013 15:10:15 +0530	[thread overview]
Message-ID: <1375782016-23975-1-git-send-email-pekon@ti.com> (raw)

GPMC registers need to be pre-initialized for NAND and NOR probe.
So this patch brings out GPMC H/W engine from IDLE state.
