Subject: [PATCH 0/2] Add Versal PUF support
Date: Tue, 7 Jul 2026 15:26:18 +0530 [thread overview]
Message-ID: <20260707095620.2795456-1-h.jain@amd.com> (raw)
Versal devices contain a physically unclonable function (PUF) block
that derives device-unique secrets from intrinsic silicon characteristics.
Add a misc character driver to support PUF registration and regeneration.
Registration generates a unique secret and outputs binary helper data
that can later be used during regeneration to reproduce the same
secrets.
