Why are we switching from Rel to Rela?
This was wrong.
Looking at the u-boot ELF binary we see these relocation sections:
arm: .rel.dyn
arm64: .rela.dyn
riscv64: .rela.dyn
In our EFI object files we currently have no relocations. This is why
tests did not complain.
In arch/arm/lib/reloc_arm_efi.c we handle DT_REL.
In arch/arm/lib/reloc_aarch64_efi.c we handle DT_RELA.
In arch/riscv/lib/reloc_riscv_efi.c we handle DT_RELA.
Best regards
Heinrich
