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. The changes are based on released DRAM code and comparing register dumps from boot0. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Acked-by: Maxime Ripard <maxime.ripard@free-electrons.com>
