devicetree: Move include prefixes from arch to separate directory

2017-05-19T06:55:48+00:00

We use a directory under arch/$ARCH/boot/dts as an include path
that has links outside of the subtree to find dt-bindings from under
include/dt-bindings. That's been working well, but new DT architectures
haven't been adding them by default.

Recently there's been a desire to share some of the DT material between
arm and arm64, which originally caused developers to create symlinks or
relative includes between the subtrees. This isn't ideal -- it breaks
if the DT files aren't stored in the exact same hierarchy as the kernel
tree, and generally it's just icky.

As a somewhat cleaner solution we decided to add a $ARCH/ prefix link
once, and allow DTS files to reference dtsi (and dts) files in other
architectures that way.

Original approach was to create these links under each architecture,
but it lead to the problem of recursive symlinks.

As a remedy, move the include link directories out of the architecture
trees into a common location. At the same time, they can now share one
directory and one dt-bindings/ link as well.

metag: enable building of all dtbs

2015-10-27T21:12:16+00:00

Enable building all dtb files when CONFIG_OF_ALL_DTBS is enabled. The dtbs
are not really dependent on a platform being enabled or any other kernel
config, so for testing coverage it is convenient to build all of the dtbs.
This builds all dts files in the tree, not just targets listed.

metag: use common make variables for dtb builds

2015-10-27T21:12:15+00:00

Use dtb-y and always make variables to build dtbs instead of explicit
dtbs rule. This is in preparation to support building all dtbs.

metag: add symlink

2013-06-27T12:49:06+00:00

Add symlink to include/dt-bindings from arch/metag/boot/dts/include/ to
match the one in arch/arm/... (see the commit below) so that
preprocessed device tree files can include various useful constant
definitions.

Commit c58299aa87544a590c62bda0bf52b69fa56cb8d5 ("kbuild: create an
"include chroot" for DT bindings") merged in v3.10-rc1.
