[PATCH 2/4] power: reset: reboot-mode: parse barebox,mode-* properties

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

The same syscon may be used both to communicate with the bootrom and
with barebox. In this case, it may be required that not all boot modes
are enabled for the OS as Linux just makes them available in turn
to userspace. Teach barebox to handle the barebox,mode- prefix the
same way it handles mode-. As Linux doesn't parse this new property,
this means that it is unproblematic to fix it up into the Linux
device tree.
