|
* @file
|
|
* @brief Board Initialization routines for OMAP3EVM.
|
|
*
|
|
* This board is based on OMAP3530.
|
|
* More on OMAP3530 (including documentation can be found here):
|
|
* http://focus.ti.com/docs/prod/folders/print/omap3530.html
|
|
*
|
|
* This file provides initialization in two stages:
|
|
* @li Boot time initialization - just get SDRAM working.
|
|
* This is run from SRAM - so no case constructs and global vars can be used.
|
|
* @li Run time initialization - this is for the rest of the initializations
|
|
* such as flash, uart etc.
|
|
*
|
|
* Boot time initialization includes:
|
|
* @li SDRAM initialization.
|
|
* @li Pin Muxing relevant for the EVM.
|
|
*
|
|
* Run time initialization includes
|
|
* @li serial @ref serial_ns16550.c driver device definition
|
|
*
|
|
* Originally from arch/arm/boards/omap/board-beagle.c
