However, MCG Hawk boards needaccess to these during the board startup code (romInit.s).These functions are provided in a separate module used withthe BOOT_EXTRA function for building compressed images. They arenot needed for any other build functions because they will beprovided directly from vxALib.o for all other images.*/#define	_ASMLANGUAGE#include "vxWorks.h"#include "asm.h"#include "regs.h"	        /* Exported internal functions */        FUNC_EXPORT(vxDecGet)		/* read decrementer */        FUNC_EXPORT(sysDebugMsg)	/* for mv2400/5100 */        _WRS_TEXT_SEG_START		/***************************************************************************** sysDebugMsg - dummy routine, just a symbol to link with** SYNOPSIS* \ss* void sysDebugMsg*     (*     char *  str,      /@ string to output @/*     UINT32  recovery  /@ 0 or EXIT_TO_SYSTEM_MONITOR @/*     )* \se** INCLUDE FILES: none** RETURNS: N/A**/FUNC_BEGIN(sysDebugMsg)        blrFUNC_END(sysDebugMsg)/***************************************************************************** vxDecGet - get the value of the decrementer register** SYNOPSIS* \ss* UINT32 vxDecGet*     (*     void*     )* \se** INCLUDE FILES: none** RETURNS: the value of the decremeter register** This assembly code is needed by hawkI2c.o, which is needed to* link boot code with.**/FUNC_BEGIN(vxDecGet)        mfdec p0        blrFUNC_END(vxDecGet)#if ((CPU == PPC603) || (CPU == PPC604) || (CPU == PPCEC603))        FUNC_EXPORT(vxHid1Get)		/* return HID1 *//***************************************************************************** vxHid1Get - get the value of the HID1 register** SYNOPSIS* \ss* UINT32 vxHid1Get*     (*     void*     )* \se** INCLUDE FILES: none** RETURNS: the value of the HID1 register** This assembly code is needed by sysSpeed.o, which we need to determine bus* and dram speed.
