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

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