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+`
binman: Add test for u-boot-spl-bss-pad Add a test that we can pad the BSS with zero bytes. Signed-off-by: Simon Glass <sjg@chromium.org> 2017-11-13 04:52:25 +00:00			`/*`

binman: Support reading the offset of an ELF-file symbol Binman needs to be able to update the contents of an ELF file after it has been build. To support this, add a function to locate the position of a symbol's contents within the file. Fix the comments on bss_data.c and Symbol while we are here.

binman: Add a function to read ELF symbols In some cases we need to read symbols from U-Boot. At present we have a a few cases which does this via 'nm' and 'grep'. It is better to use objdump since that tells us the size of the symbols and also whether it is weak or not. Add a new module which reads ELF information from files. Update existing uses of 'nm' to use this module. Signed-off-by: Simon Glass <sjg@chromium.org> 2017-11-14 01:54:54 +00:00			`* by binutils. This is used by binman tests.`
