 * 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:
