/**
 * @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
