Subject: [PATCH 0/3] DCP as trusted keys backend
Date:   Mon, 14 Jun 2021 22:16:17 +0200

DCP is an IP core found on NXP SoCs such as i.mx6ull.
While its bigger brother, CAAM, can directly wrap and unwrap blobs
in hardware[0], DCP offers only the bare minimum and the blob
mechanism needs aid from software.

This series adds support for a new trusted keys backend that makes use
of DCP's feature to use hardware keys which can never be read out.
