* Description: Configures EBC Controller and a few basic chip selects.
|

*
|
||||
* CS0 is setup to get the Boot Flash out of the addresss range

* so that we may setup a stack. CS7 is setup so that we can

|

* IMPORTANT: For pass1 this code must run from

* cache since you can not reliably change a peripheral banks
|
||||
* timing register (pbxap) while running code from that bank.
|
||||
* For ex., since we are running from ROM on bank 0, we can NOT
|
||||
* execute the code that modifies bank 0 timings from ROM, so
|
||||
* we run it from cache.
