[PATCH 0/3] ARM: support booting arbitrary ELF executables

Unlike MIPS and kvx, where ELF is used as kernel image format, Linux
ARM support defines its own flattened format.

Other kernels may be distributed as ELF images though, so it makes
sense to enable booting of ELF images on ARM as well.

This has been tested booting FreeRTOS ELF executables on the ZynqMP.

Note that this will refuse to boot kernel ELF images as those have
type dyn, while the common ELF code in barebox will only boot type exec.

  common: elf: support loading to address 0
  ARM: add support for booting ELF executables
  kbuild: support generating stripped ELF files for PBL
