   9  * EP93xx Physical Memory Map:
  10  *
  11  * The ASDO pin is sampled at system reset to select a synchronous or
  12  * asynchronous boot configuration.  When ASDO is "1" (i.e. pulled-up)
  13  * the synchronous boot mode is selected.  When ASDO is "0" (i.e
  14  * pulled-down) the asynchronous boot mode is selected.
  15  *
  16  * In synchronous boot mode nSDCE3 is decoded starting at physical address
  17  * 0x00000000 and nCS0 is decoded starting at 0xf0000000.  For asynchronous
  18  * boot mode they are swapped with nCS0 decoded at 0x00000000 ann nSDCE3
  19  * decoded at 0xf0000000.
  20  *
  21  * There is known errata for the EP93xx dealing with External Memory
  22  * Configurations.  Please refer to "AN273: EP93xx Silicon Rev E Design
  23  * Guidelines" for more information.  This document can be found at:
