From 0b4184c26b18ecbc0ec0657f514b087c3a6216fb Mon Sep 17 00:00:00 2001 From: James Hogan Date: Wed, 17 Apr 2013 10:59:22 +0100 Subject: metag: avoid unnecessary builtin dtb rebuilds The builtin .dtb.S intermediate file needs to be marked with .SECONDARY so that it isn't automatically deleted (which causes it to be regenerated on every build). Also add *.dtb.S to clean-files so it gets cleaned up by make clean. Similarly, if the specified builtin dtb isn't already in dtb-y (e.g. imported into the tree and specified in CONFIG_METAG_BUILTIN_DTB_NAME) it too will be treated as an intermediate and deleted automatically (again causing it to be regenerated on every build), so add it to dtb-y so it gets added to targets and the dtbs target.
