This adds an NVMEM reboot mode driver, similar to Linux's implementation. This allows using the same device tree binding for Linux and U-Boot in most cases. Signed-off-by: Sean Anderson <sean.anderson@seco.com> Reviewed-by: Simon Glass <sjg@chromium.org>

adjust the boot process based on reboot mode parameter

passed to U-Boot.

Use GPIOs to control the reboot mode. This will allow users to boot

a device in a specific mode by using a GPIO that can be controlled
