+ *
+ * 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).
