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)
