At present it is not possible to specify that a node should be used before relocation (in U-Boot proper) without it also ending up in SPL and TPL device trees. Add a new "u-boot,dm-pre-proper" boolean property for this. Signed-off-by: Simon Glass <sjg@chromium.org>
Make a few small updates to indicate that device tree can be used in SPL and TPL. Signed-off-by: Simon Glass <sjg@chromium.org>

In the section about Device Trees add a paragraph at the end that clarifies how we decide of a tree is valid or not. We say that all bindings must either be in the specification (link provided) or in our device-tree-bindings directory. We say that most of these come from the Linux Kernel and as such some design decisions are made for us already, but that in most cases we wish to retain compatibility.

At present all emulated sandbox pci devices must be present in the device tree in order to be used. The real world pci uclass driver supports pci device driver matching, and we should add such support on sandbox too.

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
