Documentation: Destage TEE subsystem documentation

2023-12-08T22:45:10Z

Add a separate documentation directory for TEE subsystem since it is a standalone subsystem which already offers devices consumed by multiple different subsystem drivers. Split overall TEE subsystem documentation modularly where: - The userspace API has been moved to Documentation/userspace-api/tee.rst. - The driver API has been moved to Documentation/driver-api/tee.rst. - The first module covers the overview of TEE subsystem. - The further modules are dedicated to different TEE implementations like: - OP-TEE - AMD-TEE - and so on for future TEE implementation support.

doc: rmpsg: Update with rpmsg_endpoint

2023-12-08T20:28:57Z

It seems the documentation was not updated when `rpmsg_sendto` and related switched from `rpmsg_channel` to `rpmsg_endpoint`. This change updates the proper calls, text, and the sample.

tee: optee: Add SMC for loading OP-TEE image

2023-04-03T06:57:49Z

Adds an SMC call that will pass an OP-TEE binary image to EL3 and instruct it to load it as the BL32 payload. This works in conjunction with a feature added to Trusted Firmware for ARMv8 and above architectures that supports this. The main purpose of this change is to facilitate updating the OP-TEE component on devices via a rootfs change rather than having to do a firmware update. Further details are linked to in the Kconfig file. Signed-off-by: Jeffrey Kardatzke Reviewed-by: Sumit Garg Signed-off-by: Jeffrey Kardatzke Signed-off-by: Jens Wiklander

docs: put atomic*.txt and memory-barriers.txt into the core-api book

2022-09-29T18:55:06Z

These files describe part of the core API, but have never been converted to RST due to ... let's say local oppposition. So, create a set of special-purpose wrappers to ..include these files into a separate page so that they can be a part of the htmldocs build. Then link them into the core-api manual and remove them from the "staging" dumping ground.

jump_label: make initial NOP patching the special case

2022-06-24T07:48:55Z

Instead of defaulting to patching NOP opcodes at init time, and leaving it to the architectures to override this if this is not needed, switch to a model where doing nothing is the default. This is the common case by far, as only MIPS requires NOP patching at init time. On all other architectures, the correct encodings are emitted by the compiler and so no initial patching is needed.

remoteproc: Change rproc_shutdown() to return a status

2022-03-11T20:31:55Z

The rproc_shutdown() function is currently not returning any error code, and any failures within rproc_stop() are not passed back to the users. Change the signature to return a success value back to the callers. The remoteproc sysfs and cdev interfaces are also updated to return back this status to userspace.
