On MIPS the DRAM start address respectively CONFIG_SYS_SDRAM_BASE is still used as a virtual, CPU-mapped address instead of being used as physical address. Converting all MIPS boards and generic MIPS code to fix that is not trivial. Due to the approaching deadline for PCI DM conversion, this workaround is required for MIPS boards with PCI support until the CONFIG_SYS_SDRAM_BASE issue could be solved.
Add a compile-time option to let the PCI uclass core optionally map the DRAM address to a physical address when adding the PCI region of type PCI_REGION_SYS_MEMORY.
