From 25431333813686654907ab987fb5de10c10a16db Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Thu, 7 Feb 2008 05:18:34 +1100 Subject: [POWERPC] bootwrapper: Build multiple cuImages Currently, the kernel uses CONFIG_DEVICE_TREE to wrap a kernel image with a fdt blob which means for any given configuration only one dts file can be selected and so support for only one board can be built This moves the selection of the default .dts file out of the kernel config and into the bootwrapper makefile. The makefile chooses which images to build based on the kernel config and the dts source file name is taken directly from the image name. For example "cuImage.ebony" will use "ebony.dts" as the device tree source file. In addition, this patch allows a specific image to be requested from the command line by adding "cuImage.%" and "treeImage.%" targets to the list of valid built targets in arch/powerpc/Makefile. This allows the default dts selection to be overridden. Another advantage to this change is it allows a single defconfig to be supplied for all boards using the same chip family and only differing in the device tree. Important note: This patch adds two new zImage targets; zImage.dtb.% and zImage.dtb.initrd.% for zImages with embedded dtb files. Currently there are 5 platforms which require this: ps3, ep405, mpc885ads, ep88xc, adder875-redboot and ep8248e. This patch *changes the zImage filenames* for those platforms. ie. 'zImage.ps3' is now 'zImage.dtb.ps3'. This new zImage.dtb targets were added so that the .dts file could be part of the dependancies list for building them.
