README declares that CONFIG_SYS_SDRAM_BASE is meant to be the physical address of SDRAM, but right now that is not the case on MIPS systems. In preparation for making it so, use phys_to_virt to translate CONFIG_SYS_SDRAM_BASE to the ram_top field of struct global_data which is then used to calculate most memory addresses used by U-Boot.
