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 a new sandbox_spl board It is useful to be able to build SPL for sandbox. It provides additional build coverage and allows SPL features to be tested in sandbox. However it does not need worthwhile to always create an SPL build. It nearly doubles the build time and the feature is (so far) seldom used. So for now, create a separate build target for sandbox SPL. This allows experimentation with this new feature without impacting existing workflows. Signed-off-by: Simon Glass <sjg@chromium.org>

sandbox: Align linker lists to a 32-byte boundary Use this larger boundary to ensure that linker lists at least start on the maximum possible alignment boundary. See also the CONFIG_LINKER_LIST_ALIGN setting, but that is host-arch-specific, so it seems better to use the largest value for every host architecture. Signed-off-by: Simon Glass <sjg@chromium.org>

linker_lists: Rename sections to remove . prefix Rename the sections used to implement linker lists so they begin with '__u_boot_list' rather than '.u_boot_list'. The double underscore at the start is still distinct from the single underscore used by the symbol names. Having a '.' in the section names conflicts with clang's ASAN instrumentation which tries to add redzones between the linker list elements, causing expected accesses to fail. However, clang doesn't try to add redzones to user sections, which are names with all alphanumeric and underscore characters.

sandbox: use sections instead of symbols for getopt array boundaries In style of linked lists, instead of declaring symbols for boundaries of getopt options array in the linker script, declare corresponding sections and retrieve the boundaries via static inline functions. Without this clang's LTO produces binary without any getopt options, because for some reason it thinks that array is empty (start and end symbols are at the same address).

sandbox: Rename getopt sections Rename the sections used for defining sandbox command line options so that they don't start with a '.'. ELF says that sections starting with a '.' are reserved for system use, but the sandbox runs as a normal user process so should be using user sections instead. Clang's ASAN adds redzones to non-user sections and the extra padding meant that the list of options was being corrupted. Naming the sections as user sections avoids this issue as clang handles them as we intended. Signed-off-by: Andrew Scull <ascull@google.com>

test: spl: Add functions to create images This add some basic functions to create images, and a test for said functions. This is not intended to be a test of the image parsing functions, but rather a framework for creating minimal images for testing load methods. That said, it does do an OK job at finding bugs in the image parsing directly. Since we have two methods for loading/parsing FIT images, add LOAD_FIT_FULL as a separate CI run.
