I2C4/I2C6	The proposed SMBus two-wire Interface mode is not supported for Arm Cortex-A7 secure context (TF-A , OP-TEE) as no use case foreseen.
PWR	TF-A and OP-TEE implementation do not support wakeup events for secure IPs assigned to Arm Cortex-A7 secure context.
RCC	The proposed master clock output1 and 2 as well as Audio clock input modes are not applicable to Arm Cortex-A7 secure context (TF-A, OP-TEE).
SPI6	The SPI software driver is not available in OP-TEE implementation for Arm Cortex-A7 secure context.
TAMP	OP-TEE implementation does not support TAMP_IN inputs and TAMP_OUT outputs in Arm Cortex-A7 secure context.

7. Minor release updates[edit source]

STMicroelectronics regularly delivers corrections through the following github^® components: u-boot, optee-os, tf-a, Linux kernel.
You can decide to incorporate them into your developer package (refer to STM32MP1 Developer Package) or Distribution package).
To update the Distribution package, proceed as follows:

Switch to github^® mode your Distribution package.
Use the devtool modify <recipe name> command to directly access the source code git uses by build processes.
In the source code just extracted, use the git checkout -b WORK <github^® TAG> command such to point to the new component revision.

STMicroelectronics also delivers dedicated fixes on layers through github^®. These changes can be integrated (via git commands) into your local STM32MP1 Distribution Package environment. Below the github^® links corresponding to each layer:
