*  hostInit()
*	Must never be called with type=0. You must call cpuInit for
*	hostInit(0).
*	cpuType must only be determined once, and before the cpu-specific
*	asm init code is called. This is because some CPUs can only
*	be identified by power-up register defaults that get changed
*	by the init code. So if cpuType is not set by the time we get here
*	we are in big trouble.
