Subject: [PATCH 03/10] crypto: ccp: Add bootloader and TEE version offsets
Date: Thu, 20 Apr 2023 11:31:31 -0500 [thread overview]
Message-ID: <20230420163140.14940-4-mario.limonciello@amd.com> (raw)
In-Reply-To: <20230420163140.14940-1-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.
