Hmmm, I think we want to avoid the payload having
R_AARCH64_ADR_PREL_PG_HI21* relocations due to the erratum #843419 on
some Cortex-A53.
I haven't yet looked at how you build the payload, but this may also
affects the process to do it. I will give a look on it.
Actually, I am not sure I will have time to look at it during the next
few weeks. Could you add a TODO for now?
Cheers,
