From mboxrd@z Thu Jan 1 00:00:00 1970 From: dianders@chromium.org (Doug Anderson) Date: Mon, 24 Jun 2013 13:41:57 -0700 Subject: [PATCH] ARM: Fix dtb dependency to use order-only prerequisites Message-ID: <1372106517-19105-1-git-send-email-dianders@chromium.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org The %.dtb dependency is specified to depend on the PHONY "scripts". That means that it'll build every time even if the underlying dtb file hasn't been touched. Use an order-only prerequisites to fix this. Also mark "dtbs" as PHONY for correctness. This was broken in (70b0476 ARM: 7513/1: Make sure dtc is built before running it).
