    sunxi: DRAM initialisation for sun9i · 297bb9e0
    Philipp Tomsich authored
    This adds DRAM initialisation code for sun9i, which calculates the
    appropriate timings based on timing information for the supplied
    DDR3 bin and the clock speeds used.
    With this DRAM setup, we have verified DDR3 clocks of up to 792MHz
    (i.e. DDR3-1600) on the A80-Q7 using a dual-channel configuration.
