Subject: [PATCH v3 03/10] crypto: ccp: Add bootloader and TEE version offsets
Date: Thu, 18 May 2023 22:24:41 -0500	[thread overview]
Message-ID: <20230519032448.94279-4-mario.limonciello@amd.com> (raw)
In-Reply-To: <20230519032448.94279-1-mario.limonciello@amd.com>

The bootloader and TEE versions are stored in registers that can be
accessed from sysfs.  This exports the information for recent client
and datacenter parts.
