From a881db09c073bfc043be8a7e909ac955fdd3794a Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Wed, 13 May 2015 14:54:16 +0200 Subject: [PATCH] sunxi: Fix dram initialization not working on some a33 devices When porting the allwinner dram init code to u-boot we missed some code setting an extra bit when doing auto dram config. This commits add this bit, fixing dram init not working on the ga10h 10" a33 tablet which I'm bringing up atm.
