Some devices, Buffalo Linkstation LS-XHL and LS-CHLv2 for example, power-off by restarting to letting u-boot hold the SoC until the user presses a key. Add a generic driver to implement this. It binds a function to pm_power_off, which calls arm_pm_restart.

Provides a number of drivers which either reset a complete board
|
|
or shut it down, by manipulating the main power supply on the board.
|
|
|
|
Say Y here to enable board reset and power off
|

This driver supports turning off your board via a GPIO line.
|
|
If your board needs a GPIO high/low to power down, say Y and
|
|
create a binding in your devicetree.

This driver supports turning off QNAP NAS devices by sending
|
|
commands to the microcontroller which controls the main power.
|
|

Say Y if you have a QNAP NAS.

Some boards don't actually have the ability to power off.
|
|
Instead they restart, and u-boot holds the SoC until the
|
|
user presses a key. u-boot then boots into Linux.
