Adding support for ATF means that using U-Boot on Stratix10 and Agilex without
ATF keeps working, right?

This one is included in another series already:
https://patchwork.ozlabs.org/user/todo/uboot/?series=132976

Does this mean that one will be abandonen?
So the combined hex output part of that series is not required any more?
