From 03a00be7f2062aefef0e51ef20a4c9737f6685e7 Mon Sep 17 00:00:00 2001 From: Otavio Salvador Date: Tue, 12 Sep 2017 17:36:06 -0300 Subject: kernel: Move Device Tree support to kernel.bbclass The Device Tree is commonly used but it is still kept as a .inc file instead of a proper class. Instead now we move the Device Tree code to a kernel-devicetree class and automatically enable it when the KERNEL_DEVICETREE variable is set. To avoid breakage in existing layers, we kept a linux-dtb.inc file which raises a warning telling the user about the change so in next release this can be removed.
