/*
|
|
* EP93xx Physical Memory Map:
|
|
*
|
|
* The ASDO pin is sampled at system reset to select a synchronous or
|
|
* asynchronous boot configuration. When ASDO is "1" (i.e. pulled-up)
|
|
* the synchronous boot mode is selected. When ASDO is "0" (i.e
|
|
* pulled-down) the asynchronous boot mode is selected.
|
|
*
|
|
* In synchronous boot mode nSDCE3 is decoded starting at physical address
|
|
* 0x00000000 and nCS0 is decoded starting at 0xf0000000. For asynchronous
|
|
* boot mode they are swapped with nCS0 decoded at 0x00000000 ann nSDCE3
|
|
* decoded at 0xf0000000.
|
|
*
|
|
* There is known errata for the EP93xx dealing with External Memory
|
|
* Configurations. Please refer to "AN273: EP93xx Silicon Rev E Design
|
|
* Guidelines" for more information. This document can be found at:
