firmware: qcom_scm: Add support for Qualcomm Secure Execution Environment SCM interface 2023-09-13T17:18:42+00:00 Maximilian Luz luzmaximilian@gmail.com 2023-08-27T21:14:05+00:00 00b1248606ba3979ccae30ed11df8cdc1a84245a Add support for SCM calls to Secure OS and the Secure Execution Environment (SEE) residing in the TrustZone (TZ) via the QSEECOM interface. This allows communication with Secure/TZ applications, for example 'uefisecapp' managing access to UEFI variables. For better separation, make qcom_scm spin up a dedicated child (platform) device in case QSEECOM support has been detected. The corresponding driver for this device is then responsible for managing any QSEECOM clients. Specifically, this driver attempts to automatically detect known and supported applications, creating a client (auxiliary) device for each one. The respective client/auxiliary driver is then responsible for managing and communicating with the application. While this patch introduces only a very basic interface without the more advanced features (such as re-entrant and blocking SCM calls and listeners/callbacks), this is enough to talk to the aforementioned 'uefisecapp'.
