v5: -Update commit text for "clear devices when moving execution environments" patch -Added test platform details that were missed out in the cover letter -Merged two if checks in to a single one for EE serialization patch v4: -Addressed review comments for additional info logging for EE movements -Updated switch case for EE handling in mhi_intvec_threaded_handler() v3: -Update commit text to accurately reflect changes and reasoning based on reviews v2: -Add patch to clear devices when moving execution environments During full boot chain firmware download, the PM state worker downloads the AMSS image after waiting for the SBL execution environment change in PBL mode itself. Since getting rid of the firmware load worker thread, this design needs to change and MHI host must download the AMSS image from the SBL mode of PM state worker thread instead of blocking waits for SBL EE in PBL transition processing. Ensure that EE changes are handled only from appropriate places and occur one after another and handle only PBL or RDDM EE changes as critical events directly from the interrupt handler and the status callback is given to the controller drivers promptly. When moving from SBL to AMSS EE, clear SBL specific client devices by calling remove callbacks for them so they are not left opened in a different execution environment. This patchset was tested on ARM64.
