    urara: Identity map DRAM/SRAM
    
    Using identity_map(), map the DRAM/SRAM regions to themselves (which
    happens to be using KUSEG on urara).
    
    The bootblock (which still runs in KSEG0) sets up the identity mapping
    in bootblock_mmu_init() so that ROM/RAM stages can be loaded into the
    KUSEG address range.
    
    The stack and pre-RAM CBMEM console also remain in KSEG0 since we
    don't really care about their physical addresses.
    
    Also splitting CBFS cache to pre and post RAM, to allow for larger
    rambase images.
    
    BUG=chrome-os-partner:36258
    BRANCH=none
    TEST=With the rest of coreboot and depthcharge patches applied:
        - booted urara into the kernel login prompt
        - from depthcharge CLI tried accessing memory below 0x100000 -
          observed the exception.
