u-boot-rpi* has the existing "make first page reserved" code (shown); this appears to be where any fix would go (it works without FreeBSD changes)

Hi,

I really like that you investigate in solving the breakage, thank you!
But your workflow is somewhat in the downstream direction
where it should be on the upstream.
 sysutils/u-boot-rpi* Is somewhat outdated . U-boot is currently v2020. 01 ,
so the direction should be to 1st upgrade sysutils/u-boot to v2020. 01.
After that you „test" 2020.01 , then if necessary you hack it, send a patch 
to fbsd-u-boot, and if that patch would be universal to u-boot , fbsd will send the 
patch to u-boot itself( if not yet available there).
Or vice versa fbsd will upgrade 2020.01 with a current patch from u-boot upstream .
So the first place where you should look for is the u-boot upstream.
The reason for that is that if we all hack our own versions we will completely 
out of sync. 
AFAIK ‚manu' ( e.g.  https://reviews.freebsd.org/D23592 ) is responsible 
for syncing upstreams, I would recommend you to contact him to ask where and when he wants to go
with u-boot and the DTBs and so on.
I hope this helps a little to send your work to the right addresses…

If you do sync your work with the upstream you absolutely have the right to claim your "long term fix“ . ;-)

Klaus
