* kbuild: add .SECONDARY special targetMasahiro Yamada2019-01-031-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on the following Linux commits: - 54a702f70589 ("kbuild: mark $(targets) as .SECONDARY and remove .PRECIOUS markers") - 8e9b61b293d9 ("kbuild: move .SECONDARY special target to Kbuild.include") This consolidates those two commits and adjusts commit log for barebox. GNU Make automatically deletes intermediate files that are updated in a chain of pattern rules. Example 1) %.dtb.o <- %.dtb.S <- %.dtb <- %.dts Example 2) %.o <- %.c <- %.c_shipped arch/arm/crypto/Makefile marks such targets as .PRECIOUS to prevent Make from deleting them, but the correct way is to use .SECONDARY. .SECONDARY Prerequisites of this special target are treated as intermediate files but are never automatically deleted. .PRECIOUS When make is interrupted during execution, it may delete the target file it is updating if the file was modified since make started. If you mark the file as precious, make will never delete the file if interrupted. Both can avoid deletion of intermediate files, but the difference is the behavior when Make is interrupted; .SECONDARY deletes the target, but .PRECIOUS does not. The use of .PRECIOUS is relatively rare since we do not want to keep partially constructed (possibly corrupted) targets. .SECONDARY with no prerequisites causes all targets to be treated as secondary. This agrees the policy of Kbuild. scripts/Kbuild.include seems a suitable place to add it because it is included from almost all sub-makes. I deleted 'SECONDARY' (no dot) from images/Makefile, which I guess a typo. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* arm: crypto: fix SHA256 shipped assembler codeLucas Stach2018-10-081-1/+1
| | | | | | | | | | | | | | | | Binutils 2.29 changed behavior of the adr instruction to always add the thumb mode switch offset, which breaks usages where the user is interested in the address of an internal symbol, instead of a jump address. Binutils 3.31 fixed this by only adding the offset when interworking is required. As there are toolchains out there with broken binutils, it's better to fix the code to work around the issue by not using the named label.

* arm: crypto: initialize digests earlierSascha Hauer2018-03-012-3/+3
| | | | | | | | We moved the digest init functions to coredevice_initcall level. Do the same with the ARM specific digests aswell so that they are available at the same time. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* crypto: add digest_alloc_by_algo()Sascha Hauer2016-01-262-0/+3
| | | | | | | | | | | In barebox the function digest_alloc() allocates a digest based on a string. When a subsystem already uses an integer value to identify a digest it makes no sense to create a string and pass it to digest_alloc(), where it is parsed again. This patch adds the possibility to get a digest by an enum.
