arm64: defconfig: Enable QCOMTEE module for QTEE-enabled Qualcomm SoCs

[PATCH v4] arm64: defconfig: Enable QCOMTEE module for QTEE-enabled Qualcomm SoCs

Posted by Harshal Dev 3 weeks, 4 days ago

All Qualcomm SoCs starting from SM8650 provide access to the Qualcomm
Trusted Execution Environment (QTEE) through the SMCInvoke interface,
implemented by the QCOMTEE driver. QTEE runs in the Secure World domain
on ARM64 CPUs and exposes secure services to Linux running in the Normal
World domain.

This change enables the QCOMTEE driver as a module to support
communication with QTEE.

QCOMTEE has been tested on a Qualcomm RB3Gen2 board by loading and
executing a Trusted Application via tests hosted at
github.com/qualcomm/minkipc.

Changes in v4:
- Updated the commit message as per discussion to clarify the following:
- Why we are enabling QCOMTEE for all arm64 boards.
- From which Qualcomm SoC onwards the driver is applicable.
- What functionality the driver provides.
- How the functionality has been tested and on which board.
- Link to v3: https://lore.kernel.org/r/20251208-qcom_qcomtee_defconfig-v3-1-b50dcf8ab45e@oss.qualcomm.com

Changes in v3:
- Updated the commit message to reflect the supported Qualcomm platforms.
- Link to v2: https://lore.kernel.org/r/20251205-qcom_qcomtee_defconfig-v2-1-c92560b0346e@qti.qualcomm.com

Changes in v2:
- Updated CONFIG_QCOMTEE flag to 'm' since QCOMTEE can be built as a module.
- Link to v1: https://lore.kernel.org/r/20251202-qcom_qcomtee_defconfig-v1-1-11bfe40a8ea4@oss.qualcomm.com
