license: cleanup: add SPDX Apache-2.0 license identifier Update the files which contain no license information with the 'Apache-2.0' SPDX license identifier. Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of Zephyr, which is Apache version 2. Signed-off-by: Anas Nashif <anas.nashif@intel.com>

menuconfig IPM
drivers: kconfig: unify menuconfig title strings Unify the drivers/*/Kconfig menuconfig title strings to the format "<class> [(acronym)] [bus] drivers". Including both the full name of the driver class and an acronym makes menuconfig more user friendly as some of the acronyms are less well-known than others. It also improves Kconfig search, both via menuconfig and via the generated Kconfig documentation. Signed-off-by: Henrik Brix Andersen <hebad@vestas.com>

if IPM
driver: ipm: introduce IPM_MAX_DATA_SIZE build configuration The ipm_send() allows transferring data through the IPM device. However, depending on the platform, the mailbox peripheral may either transmit a limited amount of data or not transfer data at all. Introducing this configuration allows exposing the IPM capability to the application. This commit defines a default value of 1024 bytes to avoid impacting existing IPM drivers and sets the value to 0 for the STM32 IPCC and STM32 HSEM devices. This allows, in a next step, other devices to use this configuration to expose their capabilities instead of using proprietary configuration or a static definition.

drivers: ipm: add zynqmp r5f support Add ipm driver to use Inter Processor Interrupts on Xilinx ZynqMP platform. This patch also adds sample application that shows use of xlnx ipm driver. This driver uses default arm gic interrupt controller and works only for lockstep mode of cortex-r5f cluster for now. In split mode the cortex-r5 cluster will have two r5f cores and they are expected to work in AMP mode. If both r5f cores run simultaneouly, only one of the core is able to receive IPI interrupts at this time and it will be the one that started later. In future this limitation shall be removed.

Inter Processor Interrupt driver for AMD-Xilinx

drivers: ipm: Add IPM over MBOX driver The Multi-Channel Inter-Processor Mailbox (MBOX) framework can be seen as a more general version of the Inter-Processor Mailbox (IPM) framework. An MBOX driver provides for multiple channels, where IPM provides for only a single channel of communication. Currently many applications are written to use IPM, while some are now being written to use MBOX. This means if a platform wants to support both types of apps a given it must have a driver for both frameworks. As MBOX is the newer and more generic framework, new drivers are being added for this framework only and older IPM drivers are being migrated to MBOX. This leads to the situation where applications need to be written twice, once for each framework, to run across all platforms. The solution is to add a gasket driver that exposes the IPM interface while using a MBOX driver in the back-end. This shim driver allows platforms to only need an MBOX driver to support both types of application. This IPM driver can be used when an application only supports IPM but the platform only supports MBOX. This will allow platforms and applications to be ported over to MBOX independently of each other. Add this driver here. Signed-off-by: Andrew Davis <afd@ti.com>

drivers: ipm: Select MBOX from IPM_MBOX Projects using IPM will select CONFIG_IPM=y, then the appropriate driver will be enabled based on DT. For devices using the IPM over MBOX driver this will be config IPM_MBOX. But this config depends on MBOX so if the project has not also enabled that, then this driver will not be selected. To fix this, select MBOX from IPM_MBOX. This causes the correct MBOX driver to then be selected also based on DT. This allows projects using only IPM to only need to select the same as before, MBOX will be selected as needed based on DT. Signed-off-by: Andrew Davis <afd@ti.com>
