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:
