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 21:58:06 +00:00			`# SPDX-License-Identifier: GPL-2.0+`
Kbuild: introduce Makefile in arch/$ARCH/ Introduce a Makefile under arch/$ARCH/ and include it in the top Makefile (similar to Linux kernel). This allows further refactoringi like moving architecture-specific code out of global makefiles, deprecating config variables (CPU, CPUDIR, SOC) or deprecating arch/$ARCH/config.mk. In contrary to Linux kernel, U-Boot defines the ARCH variable by Kconfig, thus the arch Makefile can only included conditionally after the top config.mk.

sandbox: Use 'extras' to specify 'head' files At present sandbox has a start.o in the 'start' target but also includes it in the normal target list. This is not how this is normally handled. It is needed because sandbox does not include the u-boot-init variable in its link rule. Update the rule and move start.o from the normal target list to the 'extras' list.

sandbox: fix build failure with musl and SDL sdl.c is compiled against the SDL library. Trying to redefine wchar_t with -fshort-wchar is not necessary and leads to build failures when compiling against musl. Cc: Milan P.
