* 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).
