 * 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 'CFG_INIT_DCACHE_CS' to be an unused chip
 *   select on the External Bus Controller (EBC) and then select a
 *   value for 'CFG_INIT_RAM_ADDR' outside of the range of valid,
 *   physical SDRAM. Otherwise, undefine 'CFG_INIT_DCACHE_CS' and
 *   select a value for 'CFG_INIT_RAM_ADDR' within the range of valid,
 *   physical SDRAM to use (3).
