This is a split merge because of non-uniform licensing of the DTC package contents and the way these components will be used in the FreeBSD environment. The original DTC package is composed of the following two major pieces: 1. sys/contrib/libfdt (BSD [dual] license) 2. contrib/dtc (GPLv2) The libfdt component is going to be shared in all aspects of the environment: - /boot/loader - kernel - dtc (the device tree compiler proper, userspace tool)
