Subject: sunxi: Reduce Orangepi PC RAM speed to 624 MHz
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=e7d6aa0b74b7f4d08ee68da8a586c76c761348e2;p=u-boot.git

sunxi: Reduce Orangepi PC RAM speed to 624 MHz

There are some reports of stability issues at 672 MHz, see:
http://linux-sunxi.org/Orange_Pi_PC#DRAM_clock_speed_limit

So reduce the DRAM speed to 624MHz which seems to be reliable everywhere.
