This series of patch adds support for vibration motors (often called vibrators) to U-Boot.
The support adds the necessary plumbing to support SPL usage of vibration motors. This can be used to vibrate the device, like a phone, as early as possible during the boot process. A `vibrator` command allows scripts, or customised boot commands, to vibrate the device. This can be used to provide feedback to the end-user about failure state, or boot stage. An example use case of the command is, in a customized boot command, to signify that an error happend, by synchronizing red LED flashes with a few short vibrations.
