cgd eb45b93a9a machine-independent TurboChannel bus configuration. These files
deal with stuff like:
	(1) configuring built-in devices,
	(2) looking at TC slots configuring any devices found.
The lists of slots, slot locations, etc. and built-in devices
are provided by machine-dependent code.  Interrupt handling
is also provided by machine-dependent code, but the MD code provides
hooks so that standard names for 'establish' and 'disestablish'
can be used in drivers.

This code requires <machine/tc_machdep.h>, which defines some
portability types specific to the TurboChannel bus code.
