/**
 * @page ti_beagle Texas Instruments Beagle Board
 *
 * Beagle Board from Texas Instruments as described here:
 * http://www.beagleboard.org
 *
 * 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 - do basics required to 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 Beagle.
 *
 * Run time initialization includes
 * @li serial @ref serial_ns16550.c driver device definition
 *
 * Originally from arch/arm/boards/omap/board-sdp343x.c
