Commit Message

Claudio Fontana May 18, 2020, 4:03 p.m. UTC 
dtc submodule update, now call the libfdt target from the new
dtc Makefile, which has been changed to not require bison, flex, etc.
This removes warnings during the build.

scripts/ symlink and tests directory creation are not necessary,
and neither is calling the clean rule explicitly.
