 * 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)
