From 15b97f5c5e6d88e0560c6928f3acd01c999a494d Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Tue, 17 Oct 2017 13:42:43 +0900 Subject: pylibfdt: move pylibfdt to scripts/dtc/pylibfdt and refactor makefile The pylibfdt is used by dtoc (and, indirectly by binman), but there is no reason why it must be generated in the tools/ directory. Recently, U-Boot switched over to the bundled DTC, and the directory structure under scripts/dtc/ now mirrors the upstream DTC project. So, scripts/dtc/pylibfdt is the best location. I also rewrote the Makefile in a cleaner Kbuild style. The scripts from the upstream have been moved as follows: lib/libfdt/pylibfdt/setup.py -> scripts/dtc/pylibfdt/setup.py lib/libfdt/pylibfdt/libfdt.i -> scripts/dtc/pylibfdt/libfdt.i_shipped The .i_shipped is coped to .i during building because the .i must be located in the objtree when we build it out of tree.
