[PATCH v2 0/4] firmware: raspberrypi: Add support for the tryboot mode

[Gregor Herburger]

This adds support for the tryboot mode on Raspberry Pis. As there is no
documentation other than the downstream implementation [0] the
implementation is based on this.

I tested this on Raspberry Pi 5 and therefore I only added the
properties to this devicetree. But afaik this should work on all
Raspberry Pis. I will add it to the correspondings dts if I get some
hardware to test it.
