Hi Clement,

I tested the series on the stm32 platform for remote proc firmwre load: no regression found.
I do not test the da_to_va feature as not implemented on stm32 platform.

Regards,
Arnaud

This serie add support for elf64 in remoteproc (elf loader, coredump). 
First two patches modifies the type of len argument (in da_to_va) and
boot_addr in order to allow loading elf64 segment with a u64 size
and a u64 entry point.
Next patch introduce a set of macros to access elf64 and elf32
transparently.
Last two patches are the actual modification in the elf loader and
remoteproc coredump support to add elf64 support.

Changes from V3:
 - Adapt coredump to elf64 file format
 - Rename remoteproc_elf_loader.h to remoteproc_elf_helpers.h
 - Update copyright year in remoteproc_elf_helpers.h
 - Rename macros elf_hdr_* to elf_get_hdr_* for coherency with elf_hdr_set_*
 - Split elf64 loader patch in 3:
   - boot_addr u64 change
   - remoteproc_elf_helpers.h creation
   - elf64 loading

Clement Leger (5):
  remoteproc: Use u64 len for da_to_va
  remoteproc: Use u64 type for boot_addr
  remoteproc: Add elf helpers to access elf64 and elf32 fields
  remoteproc: Add elf64 support in elf loader
  remoteproc: Adapt coredump to generate correct elf type
