Bootmenu requires an input device with arrows and enter key. A common smartphone luckily has power, volume up/down buttons, which may be used for controlling bootmenu.
Button keyboard driver relies on button driver - iterates over all button with linux,code, checks state and sends events. Add support for linux,code in button driver. Fix qcom pwr-key gpio driver to work with button driver.
