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

[Fabien Dessenne]

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.

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
