40 * Platform Specific Information and Function Hooks.
42 * The tags family and model information are strings describing the platform.
44 * The tag iobus describes the primary iobus for the platform- primarily
45 * to give a hint as to where to start configuring. The likely choices
46 * are one of tcasic, lca, apecs, cia, or tlsb.

89 * There is an array of functions to initialize the platform structure.
91 * It's responsible for filling in the family, model_name and iobus
92 * tags. It may optionally fill in the cons_init, device_register and
93 * mcheck_handler tags.
95 * The iointr tag is filled in by set_iointr (in interrupt.c).
96 * The clockintr tag is filled in by cpu_initclocks (in clock.c).
98 * nocpu is function to call when you can't figure what platform you're on.
99 * There's no return from this function.
