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>

sandbox: Add SDL library for LCD, keyboard, audio SDL (Simple DirectMedia Layer - see www.libsdl.org) is a library which provides simple graphics and sound features. It works under X11 and also with a simple frame buffer interface. It is ideally suited to sandbox U-Boot since it fits nicely with the low-level feature set required by U-Boot. For example, U-Boot has its own font drawing routines, its own keyboard processing and just needs raw sound output. We can use SDL to provide emulation of these basic functions for sandbox. This significantly expands the testing that is possible with sandbox. Add a basic SDL library which we will use in future commits.

sandbox: Add support for Address Sanitizer Add CONFIG_ASAN to build with the Address Sanitizer. This only works with the sandbox so the config is likewise dependent. The resulting executable will have ASAN instrumentation, including the leak detector that can be disabled with the ASAN_OPTIONS environment variable: ASAN_OPTIONS=detect_leaks=0 ./u-boot Since u-boot uses its own dlmalloc, dynamic allocations aren't automatically instrumented, but stack variables and globals are. Instrumentation could be added to dlmalloc to poison and unpoison memory as it is allocated and deallocated, and to introduce redzones between allocations. Alternatively, the sandbox may be able to play games with the system allocator and somehow still keep the required memory abstraction. No effort to address dynamic allocation is made by this patch.

build: use thin archives instead of incremental linking Currently we use incremental linking (ld -r) to link several object files from one directory into one built-in.o object file containing the linked code from that directory (and its subdirectories). Linux has, some time ago, moved to thin archives instead. Thin archives are archives (.a) that do not really contain the object files, only references to them. Using thin archives instead of incremental linking - saves disk space - apparently works better with dead code elimination - makes things easier for LTO The third point is the important one for us. With incremental linking there are several options how to do LTO, and that would unnecessarily complicate things. We have to use the --whole-archive/--no-whole-archive linking option instead of --start-group/--end-group, otherwise linking may fail because of unresolved symbols, or the resulting binary will be unusable.
