SPDX: Convert all of our single license tags to Linux Kernel style 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>

binman: Move to absolute imports At present binman sets the python path on startup so that it can access the libraries it needs. If we convert to use absolute imports this is not necessary. Move binman to use absolute imports. This enables removable of the path adjusting in Entry also. Signed-off-by: Simon Glass <sjg@chromium.org>

binman: Support updating all device tree files Binman currently supports updating the main device tree with things like the position of each entry. Extend this support to SPL and TPL as well, since they may need (a subset of) this information. Also adjust DTB output files to have a .out extension since this seems clearer than having a .dtb extension with 'out' in the name somwhere. Also add a few missing comments and update the DT setup code to use ReadFile and WriteFile(). Signed-off-by: Simon Glass <sjg@chromium.org>

binman: Adjust GetFdt() to be keyed by etype At present the FDTs are keyed by their default filename (not their actual filename). It seems easier to key by the entry type, since this is always the same for each FDT type. To do this, add a new Entry method called GetFdtEtype(). This is necessary since some entry types contain a device tree which are not the simple three entry types 'u-boot-dtb', 'u-boot-spl' or 'u-boot-tpl'. The code already returns a dict for GetFdt(). Update the value of that dict to include the filename so that existing code can work. Signed-off-by: Simon Glass <sjg@chromium.org>
