  * Initial RAM & Stack Pointer Configuration Options
  *
  *   There are traditionally three options for the primordial
  *   (i.e. initial) stack usage on the 405-series:
  *
  *      1) On-chip Memory (OCM) (i.e. SRAM)
  *      2) Data cache
  *      3) SDRAM
  *
  *   For the 405EX(r), there is no OCM, so we are left with (2) or (3)
  *   the latter of which is less than desireable since it requires
  *   setting up the SDRAM and ECC in assembly code.
  *
  *   To use (2), define 'CONFIG_SYS_INIT_DCACHE_CS' to be an unused chip
  *   select on the External Bus Controller (EBC) and then select a
  *   value for 'CONFIG_SYS_INIT_RAM_ADDR' outside of the range of valid,
  *   physical SDRAM. Otherwise, undefine 'CONFIG_SYS_INIT_DCACHE_CS' and
  *   select a value for 'CONFIG_SYS_INIT_RAM_ADDR' within the range of valid,
  *   physical SDRAM to use (3).
