The timer defines are only used in core.c. Move them so they will not be globaly exposed. While here, add additional defines to document the magic numbers used in the registers. Also, add some comments for clarification.

/*
|
|
* 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:
