* Initial RAM & Stack Pointer Configuration Options

*
* 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).
