We don't have audio support in U-Boot, but we do have boot menus. Add an option to re-map the volume and power buttons to up/down/enter so that in situations where these are the only available buttons (such as on mobile phones) it's still possible to navigate menus built in U-Boot or an external EFI app like GRUB or systemd-boot.

Many boards have buttons which can be used to change behaviour (reset, ...).
|
|
U-Boot provides a uclass API to implement this feature. Button drivers
|
|
can provide access to board-specific buttons. Use of the device tree
|
|
for configuration is encouraged.

Enable remapping of phone keys to navigation keys. This is useful for
|
|
devices with phone keys that are not used in U-Boot. The phone keys
|
|
are remapped to the following navigation keys:
|
|
- Volume up: Up
|
|
- Volume down: Down
|
|
- Power: Enter
