You need to update doc/board/index.rst as well, otherwise you get:
Warning, treated as error:
/home/trini/work/u-boot/u-boot/doc/board/variscite/index.rst:document isn't included in any toctree
make[1]: *** [doc/Makefile:68: htmldocs] Error 2
make: *** [Makefile:2250: htmldocs] Error 2

The easiest way to test doc building is:
$ virtualenv -p /usr/bin/python3 /tmp/venv
$ ( . /tmp/venv/bin/activate ; pip install -r doc/sphinx/requirements.txt ; make htmldocs)

Thanks!
