19 * EP93xx Physical Memory Map:
20 *
21 * The ASDO pin is sampled at system reset to select a synchronous or
22 * asynchronous boot configuration.  When ASDO is "1" (i.e. pulled-up)
23 * the synchronous boot mode is selected.  When ASDO is "0" (i.e
24 * pulled-down) the asynchronous boot mode is selected.
25 *
26 * In synchronous boot mode nSDCE3 is decoded starting at physical address
27 * 0x00000000 and nCS0 is decoded starting at 0xf0000000.  For asynchronous
28 * boot mode they are swapped with nCS0 decoded at 0x00000000 ann nSDCE3
29 * decoded at 0xf0000000.
30 *
31 * There is known errata for the EP93xx dealing with External Memory
32 * Configurations.  Please refer to "AN273: EP93xx Silicon Rev E Design
33 * Guidelines" for more information.  This document can be found at:
