*
* 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
