If the patch files are in place for what poudriere uses
for /usr/ports/sysutils/u-boot-rpi-arm64/ , poudriere
based port building should then work.

Is there a log file of the port build output that you
could post? For manual make activity one can use something
like the script command to also have the output sent out
to a log file.

The output during the make would be a good cross check
on what is in the build and if the patches are being
applied to a fresh extraction of the source code.

Those 570's indicate the smaller file size. The larger
size from being a debug build is likely to be more like
587.

(Your and my checksums would be unlikely to match
due to details of build environment differences
that control some aspects of code generation. But
the sizes should be similar.)

The sum output, of itself, does not show file timestamps
and more detailed size figures that would also be evidence.

Did the build sequence re-extract the source code and
apply all the patch files to the result?

As expected, given the u-boot.bin is too small to be
a debug build. Until you produce the bigger variant
of the file, there will be no debug or other logging.
Probably no reason to even copy over the smaller file
variants to the boot media.
