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