This driver enabled us to drive the reboot of the Versatile family of ARM reference boards. Even though only the RealView boards are supported initially, these boards all have the same procedure for reboot: - Write a magic value into an unlocking register - Write another magic value into a reset control register The driver will be reusable for Versatile and possibly also the Integrator family of reference boards.

Some boards don't actually have the ability to power off.

Instead they restart, and u-boot holds the SoC until the
