Subject: [PATCH v5 0/5] firmware: raspberrypi: Add support for the tryboot mode
Date: Fri, 02 Oct 2026 11:53:39 +0200 [thread overview]
Message-ID: <20261002-rpi-tryboot-v5-0-6294c131e583@linutronix.de> (raw)
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.
Tested on Raspberry Pi 4 and Raspberry Pi 5.
