Add initial support for the Renesas Salvator-X 2nd version development board equipped with an R-Car M3-W+ SiP with 8 (2 x 4) GiB of RAM. The memory map is as follows: - Bank0: 4GiB RAM : 0x000048000000 -> 0x000bfffffff 0x000480000000 -> 0x004ffffffff - Bank1: 4GiB RAM : 0x000600000000 -> 0x006ffffffff Based on a patch in the BSP by Takeshi Kihara <takeshi.kihara.df@xxxxxxxxxxx>.
