Subject[PATCH v5 1/2] dt-bindings: reserved-memory: Open Profile for DICE
From
Add DeviceTree bindings for Open Profile for DICE, an open protocol for
measured boot. Firmware uses DICE to measure the hardware/software
combination and generates Compound Device Identifier (CDI) certificates.
These are stored in memory and the buffer is described in the DT as
a reserved memory region compatible with 'google,open-dice'.
