Make it possible to invoke rescue boot from U-Boot console, without having to press the factory reset button. This is needed when accessing the device remotely, for example. Achieve this by putting rescue command into `bootcmd_rescue` default environment variable and setting some distroboot environment variables to their default values when the factory button is pressed. Rescue boot from console can be invoked by running run bootcmd_rescue Signed-off-by: Marek Behún <marek.behun@nic.cz> Reviewed-by: Pali Rohár <pali@kernel.org> Reviewed-by: Stefan Roese <sr@denx.de>
