 * This gets called after board-specific INIT_MACHINE, and initializes most
 * on-chip peripherals accessible on this board (except for few like USB):
 *
 *  (a) Does any "standard config" pin muxing needed.  Board-specific
 *	code will have muxed GPIO pins and done "nonstandard" setup;
 *	that code could live in the boot loader.
 *  (b) Populating board-specific platform_data with the data drivers
 *	rely on to handle wiring variations.
 *  (c) Creating platform devices as meaningful on this board and
 *	with this kernel configuration.
 *
 * Claiming GPIOs, and setting their direction and initial values, is the
 * responsibility of the device drivers.  So is responding to probe().
 *
 * Board-specific knowlege like creating devices or pin setup is to be
 * kept out of drivers as much as possible.  In particular, pin setup
 * may be handled by the boot loader, and drivers should expect it will
 * normally have been done by the time they're probed.
