From 71e6a19fe2669faf7dcb96ba8a4fde927485e60e Mon Sep 17 00:00:00 2001 From: Tze Yee Ng Date: Tue, 2 Jun 2026 22:28:42 -0700 Subject: firmware: stratix10-svc: Add support to query Arm Trusted Firmware (ATF) version Add entry in Stratix10 service layer that allow client to retrieve the ATF version at runtime, which is useful for system diagnostics, compatibility checks, and ensuring the correct secure firmware is in use. The change introduces: - A new service command definition in the Stratix10 service layer to initiate the ATF version query. - A corresponding macro definition in the header file to expose the command ID for use by other components. The service layer uses a Secure Monitor Call (SMC) to communicate with the ATF and retrieve the version string, which can then be logged or validated by client application.
