sunxi: add sun7i cpu, board and start of day support This patch adds generic board, start of day and basic build system support for the Allwinner A20 (sun7i) processor. This code will not been compiled until the build is hooked up in a later patch. It has been split out to keep the patches manageable.

sunxi: DRAM: add Allwinner H5 support The DRAM controller in the Allwinner H5 SoC is again very similar to the one in the H3 and A64. Based on the existing socid parameter, add support for this controller by reusing the bulk of the code and only deviating where needed. These new bits set or cleared here and there have been mostly found by looking at DRAM register dumps after using the H5 boot0 and comparing them to what we set in the code. So for now it's mostly unclear what those bits actually mean - hence the missing names and comments. Also add the delay line parameters taken from the boot0 and libdram disassembly. Register setup differences between H5 and H3 are courtesy of Jens Kuske. Signed-off-by: Andre Przywara <andre.przywara@arm.com> Acked-by: Maxime Ripard <maxime.ripard@free-electrons.com>

sunxi: Use H3/A64 DRAM initialization code for R40 The R40 seems to have a variant of the memory controller found in the H3 and A64 SoCs. Adapt the code for use on the R40.
