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.
