Yes but not entirely enough right now.

See: 
https://lore.kernel.org/u-boot/20250129-px30-overlay-v1-0-4729b3fcb4c0@cherry.de/T/#t

At least it still boots even if fdtoverlay_addr_r isn't set so that's 
not too much of an issue.

Would be nice to check which SoCs do not have this fdtoverlay_addr_r set 
and actually set it as well, otherwise enabling this doesn't help much 
:) (at least with pxe/extlinux)

Cheers,
Quentin
