Hi,

The goal of this series is to be able to use the generic loader
on heterogeneous binary. In order to do that we need to remove
its target_words_bigendian() call. This series replace the
'bool is_big_endian' (~equivalent) argument of load_elf*() API
by ELFDATA (which can be LSB / MSB or NONE), updating all the
call sites.

Philippe Mathieu-Daudé (6):
  hw/avr/boot: Replace load_elf_ram_sym() -> load_elf_as()
  hw/loader: Remove unused load_elf_ram()
  hw/loader: Clarify local variable name in load_elf_ram_sym()
  hw/loader: Pass ELFDATA endian order argument to load_elf_ram_sym()
  hw/loader: Pass ELFDATA endian order argument to load_elf_as()
  hw/loader: Pass ELFDATA endian order argument to load_elf()

Thanks, series queued squashing:
