Subject: [PATCH 5/7] arm64: dts: add support for per sub-dir makefiles for DT building
Date: Tue, 28 Aug 2018 15:32:10 +0300	[thread overview]
Message-ID: <1535459532-17211-6-git-send-email-t-kristo@ti.com> (raw)
In-Reply-To: <1535459532-17211-1-git-send-email-t-kristo@ti.com>

Currently the makefile for arm64 builds all the DT files based on
rules in the arch/arm64/boot/dts/Makefile, as this is statically
passed via the $(build)= parameter. Change the $(build) parameter
to actually point to the subdir itself, so the makefile from
that subdir can be used to set-up build flags etc., for example
setting up DTC_FLAGS. The patsubst magic is used to strip the
trailing "/" from the path, as that confuses the kbuild system.
