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.
