[linux-sunxi] [PATCH u-boot-sunxi] sunxi: initialize DRAM after AXP

2014-05-12 Thread Siarhei Siamashka
The default dcdc3 voltage is only 1.2V after reset on the Cubietruck. This might be too low for correct DRAM controller operation at high clock frequencies and even the initialization itself may theoretically fail. So we initialize AXP first. And only then move on to the DRAM setup. Signed-off-by:
