Depending on the timing, you can just fold it into your patch (basically removing the MACHINE argument, adding KBUILD_DTBS and dtbs target help). It's been derived from your arch/arm patch anyway ;). --=20 Catalin --wRRV7LY7NUeQGEoC Content-Type: text/x-diff; charset=WINDOWS-1252 Content-Transfer-Encoding: quoted-printable Content-Disposition: attachment; filename="0001-arm64-Add-dtbs-target-for-building-all-the-enabled-d.patch" >From 906ea5523f1a5c2fadea72b54d5d6a8e5fecdfe5 Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Wed, 21 Nov 2012 11:44:59 +0000 Subject: [PATCH] arm64: Add dtbs target for building all the enabled dtb files Based on Rob Herring's patches for arch/arm, this patch adds a dtbs target to arch/arm64/boot/Makefile.
