Subject: [PATCH 0/2] arm: socfpga: agilex5: add VAB verification for SSBL
Date: Wed, 21 Oct 2026 22:33:51 +0200 [thread overview]
Message-ID: <20261021-socfpga-agilex5-verify-ssbl-v1-0-0463e94669ab@pengutronix.de> (raw)
If Vendor Authorized Boot (VAB) is enabled on Agilex 5, the firmware
checks the signature of the first stage loader. If the first stage
loader loads the second stage (SSBL) from flash, the first stage loader
is then responsible for checking the authenticity of the SSBL.
Add support for verifying a certificate that is attached to an SSBL and
rejecting an SSBL with an invalid certificate if VAB is enabled.
