The decompression stub inflates the main VxWorks code into RAM,				and then jumps to it. This is the entry point (i.e., the first address).				It is important not to add any other routines before this one.				*/								#include "vxWorks.h"				#include "usrConfig.h"								/******************************************************************************				*				* usrEntry - entry point for _romCompress and _rom images.				*/ 								void usrEntry (int startType)				    {				#if     (CPU_FAMILY==I960)				    sysInitAlt (startType);             /* jump to the i960 entry point */				#endif								#if (CPU_FAMILY==MIPS) && __GNUC__				    __asm volatile (".extern _gp,0; la $gp,_gp");				#endif								    usrInit (startType);                /* all others procede below */				    }
