	19	* Description:
	20	* This routine performs initializations assuming a Fido
	21	* development board. In order, the following functions are performed:
	22	*
	23	* -- memory offset register initialization
	24	* -- chip select register initialization for external memory
	25	* -- SDRAM ctrl register initialization for external memory
	26	* -- in line test of external SRAM
	27	* -- sets user SP for MasterContext0 (main)
	28	* -- copies the bss section to RAM
	29	* -- transfers control to MasterContext0 (main)
