OK. I was hoping that we could just automate as part of the regular
build process seeing for example $(BOARD)/foo.xml and invoking the
script to re-create foo.c and so forth, but that doesn't seem to be the
case. So, no Makefile logic. We should then instead start on some
content for doc/board/socfpga/ and document this tool there. Thanks!
