From 36dd5f1b8abcd0aa5f8490b3ef1e4e7ecce2eb8c Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Sat, 23 Sep 2017 13:00:57 -0400 Subject: [PATCH] dtc: Switch to building and using our own dtc unless provided This makes us act like the Linux Kernel does and allow for dtc to be provided externally but otherwise we use the version of dtc that is included in the sources. This in turn means that we can drop the checkdtc logic. We select DTC in the cases where we will need the dtc tool provided.
