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> 2018-05-06 17:58:06 -04:00			`# SPDX-License-Identifier: GPL-2.0`
kernel-doc: move kernel-doc tools to scripts/ tools/kernel-doc/docproc.c and tools/kernel-doc/kernel-doc are files imported from Linux Kernel. They originally resided under scripts/ directory in Linux Kernel. This commit moves them to the original location.

cmd: add a new command "config" to show .config contents This feature is inspired by /proc/config.gz of Linux. In Linux, if CONFIG_IKCONFIG is enabled, the ".config" file contents are embedded in the kernel image. If CONFIG_IKCONFIG_PROC is also enabled, the ".config" contents are exposed to /proc/config.gz. Users can do "zcat /proc/config.gz" to check which config options are enabled on the running kernel image. The idea is almost the same here; if CONFIG_CMD_CONFIG is enabled, the ".config" contents are compressed and saved in the U-Boot image, then printed by the new command "config". The usage is quite simple. Enable CONFIG_CMD_CONFIG, then run > config from the command line interface. The ".config" contents will be printed on the console. This feature increases the U-Boot image size by about 4KB (this is mostly due to the gzip-compressed .config file). By default, it is enabled only for Sandbox because we do not care about the memory footprint on it. Of course, this feature is architecture agnostic, so you can enable it on any board if the image size increase is acceptable for you.

kbuild: use scripts/Makefile.clean This commit refactors cleaning targets such as clean, clobber, mrpropper, distclean with scripts/Makefile.clean. By using scripts/Makefile.clean, we can recursively descend into subdirectories and delete generated files there. We do not need add a big list of generated files to the "clean" target.

scripts: Makefile: also clean subdir dtc Since commit 93b196532254 ("Makefile: Only build dtc if needed"), the sub directory scripts/dtc is never cleaned. Adds the directory dtc to subdir to always clean it.
