9 * EP93xx Physical Memory Map:
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.
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.
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:
