STMicrolectronics STM32MP157 MPU are based on a Dual Arm Cortex-A7 core and a Cortex-M4. This patchset adds the support of the stm32_rproc driver allowing to control the M4 remote processor. Changes since v1: - Gave details about the memory mapping (in bindings). - Used 'dma-ranges' instead of 'ranges'. - Updated the 'compatible' property. - Remove the 'recovery', 'reset-names' and 'interrupt-names' properties. - Clarified why / when mailboxes are optional.
