|

* defintions about memory sizes and locations.
|
|
*
|
|
* Note that this definition should only be used for simple applications
|
|
* where memory is all cached and identity-mapped. More complicated
|
|
* memory arrangements should be described in platform-specific code,
|
|
* rather than complicating this table.

|
|
* For some platforms/targets, SDRAM_LEN is not constant and so we
|
|
* have to compute a maximum via other means.
