Helper build scripts don't belong in the tools directory. If they're
super helpful, I don't object to adding them to
u-boot-extras/contrib/<you>/ directory.
OK
But there's a number of
documented examples already on checkout and build TF-A then do ... for
your platform.
There is doc/board/xilinx/zynqmp.rst which deals with quite few ZynqMP
boards but not the KV260. In addition, it has a number of shortcomings:
- It mentions pmu.bin but does not say where to get if from
- It doesn't say how to build TF-A (bl31.bin), some very specific build
options are needed.
- I consider that detailed build instructions belong in things called
scripts or Makefiles, that were invented long ago exactly for that
purpose :) IMO the documentation should tell the bare minimum and ideally
be unnecessary.
I am not particularly proud of the fact that I spent more than a whole
day trying to get U-Boot master to boot on my KV260, and without the help
of Michal, no doubt I would still be trying... So, how about I submit the
zynqmp_kv260_build.sh script to the u-boot-extras/contrib/<me>/ directory
and just point to it in doc/board/xilinx/zynqmp.rst?
no issue from my side.
OK so here you go:

I would create one variable to keep xlnx_rel_v2025.1 string that you can change
one location to get new versions.

here you have bug. Your script works fine on the first run.
You can try this
./zynqmp_kv260_build.sh
make mrproper
./zynqmp_kv260_build.sh
and look at
CONFIG_BL31_LOAD_ADDR
you are all the time getting default Kconfig address which is wrong.
