Hi Fabien,
This patchset adds an STM32 remoteproc driver.
Patch 1 adds the xxx_translate_dma_address() API which is the equivalent of the xxx_translate_address() relying on the "dma-ranges" property instead of the "ranges" property.
Patch 2 fixes and completes function headers of remoteproc.h.
Patch 3 & 4 add the support of the ELF image loading (the current implementation supports only binary image loading).
Patch 5 is about the driver, and patches 6 & 7 are about MAINTAINERS and configs update.
Thank you for your work - the Vybrid VF610 also has Cortex-M4/M3 embedded and (probably) in some future somebody will want to setup it in U-Boot. Those changes looks generic and shall be easily re-usable.
Thanks one more time.
Changes since v2: -Moved helpers to rproc-elf-loader.c -Rename *elf* functions in *elf32*, preparing future support for elf64 Changes since v1: -Added tests for rproc_elf*() and *_translate_dma_address() -Changed memory translation ops from da_to_pa() to device_to_virt() : the name is updated and the translation now converts to virtual instead of physical. -Merged rproc_elf_is_valid() in rproc_elf_sanity_check() -Used explicit error values in rproc_elf_sanity_check() -Added and fix comments in various headers -Misc minor changes
