  60  *   (i.e. initial) stack usage on the 405-series:
  61  *
  62  *      1) On-chip Memory (OCM) (i.e. SRAM)
  63  *      2) Data cache
  64  *      3) SDRAM

  66  *   For the 405EX(r), there is no OCM, so we are left with (2) or (3)
  67  *   the latter of which is less than desireable since it requires
  68  *   setting up the SDRAM and ECC in assembly code.

  71  *   select on the External Bus Controller (EBC) and then select a

  73  *   physical SDRAM. Otherwise, undefine 'CONFIG_SYS_INIT_DCACHE_CS' and
