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: Add tests binaries with binman symbols For testing we need to build some ELF files containing binman symbols. Add these to the Makefile and check in the binaries: u_boot_binman_syms - normal, valid ELF file u_boot_binman_syms_bad - missing the __image_copy_start symbol u_boot_binman_syms_size - has a binman symbol with an invalid size Signed-off-by: Simon Glass <sjg@chromium.org>

spl: binman: Split binman symbols support from enabling binman Enabling CONFIG_BINMAN makes binman run after a build to package any images specified in the device-tree. It also enables a mechanism for SPL/TPL to declare and use special linker symbols that refer to other entries in the same binman image. A similar feature that gets this info from the device-tree exists for U-Boot proper, but it is gated behind a CONFIG_BINMAN_FDT unlike the symbols. Confusingly, CONFIG_SPL/TPL_BINMAN_SYMBOLS also exist. These configs don't actually enable/disable the symbols mechanism as one would expect, but declare some symbols for U-Boot using this mechanism. Reuse the BINMAN_SYMBOLS configs to make them toggle the symbols mechanism, and declare symbols for the U-Boot phases in a dependent BINMAN_UBOOT_SYMBOLS config. Extend it to cover symbols of all phases. Update the config prompt and help message to make it clearer about this. Fix binman test binaries to work with CONFIG_IS_ENABLED(BINMAN_SYMBOLS).

binman: Support symbols in u-boot-spl-nodtb Since this is an execuable we should be able insert symbol values into it. Add support for this. Use common code for this test and the original testSymbols. Use hex consistently for the values and add some more comments. Signed-off-by: Simon Glass <sjg@chromium.org>

binman_sym_declare(unsigned long, u_boot_spl_any, offset);
binman: Rename 'position' to 'offset' After some thought, I believe there is an unfortunate naming flaw in binman. Entries have a position and size, but now that we support hierarchical sections it is unclear whether a position should be an absolute position within the image, or a relative position within its parent section. At present 'position' actually means the relative position. This indicates a need for an 'image position' for code that wants to find the location of an entry without having to do calculations back through parents to discover this image position. A better name for the current 'position' or 'pos' is 'offset'. It is not always an absolute position, but it is always an offset from its parent offset. It is unfortunate to rename this concept now, 18 months after binman was introduced. However I believe it is the right thing to do. The impact is mostly limited to binman itself and a few changes to in-tree users to binman: tegra sunxi x86 The change makes old binman definitions (e.g. downstream or out-of-tree) incompatible if they use the 'pos = <...>' property. Later work will adjust binman to generate an error when it is used. Signed-off-by: Simon Glass <sjg@chromium.org>

binman_sym_declare(unsigned long long, u_boot_spl2, offset);
binman: Add a new 'image-pos' property At present each entry has an offset within its parent section. This is useful for figuring out how entries relate to one another. However it is sometimes necessary to locate an entry within an image, regardless of which sections it is nested inside. Add a new 'image-pos' property to provide this information. Also add some documentation for the -u option binman provides, which updates the device tree with final entry information. Since the image position is a better symbol to use for the position of U-Boot as obtained by SPL, update the SPL symbols to use this instead of offset, which might be incorrect if hierarchical sections are used.

binman: Allow support for writing a size symbol to binaries It is useful to be able to access the size of an image in SPL, with something like: binman_sym_declare(unsigned long, u_boot_any, size); ... ulong u_boot_size = binman_sym(ulong, u_boot_any, size); Add support for this and update the tests.
