I hope that we haven't start to mix 2 things together - low level configuration
generation and u-boot itself.

Vivado or EDK are able to generate ps7_init.c/h files from design tool
and you can use if for board configuration. (FSBL uses them too).
If you like it then just use tool for generation.

If you don't like it like Andrey then feel free to create any software
for better ps7_init generation.
Andrey has done that and it is really nice to see it working
and I really appreciate all his work.


For u-boot itself is shouldn't matter if you take this file from
xilinx tools or from your tools but u-boot source code
should just work with both. It means top level configuration function
should be the same. I have chosen ps7_init() because I am not
able to change tools behaviour.

Currently low level configuration is run in u-boot SPL
where ps7_init() is called. If you want to run just full u-boot
from OCM we can look at it.

Thanks,
Michal
