[U-Boot] [PATCH v3 0/7] Add STM32 Cortex-M4 remoteproc driver

[Lukasz Majewski]

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
