* 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 knowledge 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.
