/**
* @file
* @brief Board Initialization routines for the phyCARD-A-L1
*
* 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
