With these versal_ipi_cmd_*() functions datawords ("Values") and "IPI buffers" can easily be "pushed" onto a structversal_ipi_cmd.For now, only this OCP driver makes use of these versal_ipi_cmd_*()functions. Thus they have been placed directly in versal_ocp.c instead ofhaving them located in a separate drivers/ file, likedrivers/versal_ipi_cmd.c [1].Link: https://github.com/OP-TEE/optee_os/pull/7726#issuecomment-4237954478 [1]Signed-off-by: Dennis Ries <dennis.ries@missinglinkelectronics.com>Signed-off-by: Joachim Foerster <joachim.foerster@missinglinkelectronics.com>Reviewed-by: Nathan Menhorn <nathan.menhorn@amd.com>Tested-by: Nathan Menhorn <nathan.menhorn@amd.com>Reviewed-by: Sean McGinn <sean.mcginn@amd.com>Reviewed-by: Lucas Kiker <lucas.kiker@amd.com>Reviewed-by: Sindhu Raveendra <Sindhu.Raveendra@amd.com>Reviewed-by: Clemens Nasenberg <clemens.nasenberg@amd.com>Reviewed-by: Jorge Ramirez-Ortiz <jorge.ramirez@oss.qualcomm.com> List of files: /optee_os/core/include/drivers/versal_ocp.h Thu, 08 Jan 2026 14:51:21 +0000 Dennis Ries <dennis.ries@missinglinkelectronics.com>
