2016-10-30sunxi: add initial clock setup for sun9i for SPLPhilipp Tomsich
This is a cleaned up version set_pll() from Allwinner's boot0 source (bootloader/basic_loader/bsp/bsp_for_a80/common/common.c). [wens@csie.org: Added commit message; style cleanup] Signed-off-by: Chen-Yu Tsai <wens@csie.org> Acked-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com>
2016-10-30sunxi: DRAM initialisation for sun9iPhilipp Tomsich
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.
