2018-11-29test: Add a 'make qcheck' target for quicker testingSimon Glass
At present tests are quite slow to run, over a minute on my machine. This presents a considerable barrier to bisecting for failures. The slowest tests are the filesystem ones and the buildman --fetch-arch test. Add a new 'qcheck' target that skips these tests. This reduces test time down to about 40 second, still too long, but bearable. Signed-off-by: Simon Glass <sjg@chromium.org>

2018-09-25Makefile: Use -fno-strict-aliasing globallyBin Meng
The -fstrict-aliasing option is implicitly enabled at levels -O2, -O3, -Os by GCC. This option allows the compiler to assume the strictest aliasing rules applicable to the language being compiled. For example, the practice of reading from a different union member than the one most recently written to (called "type-punning") is common. In this case, "type-punning" only works if the memory is accessed through the union type, but might not work by taking the address, casting the resulting pointer and dereferencing the result, which is an undefined behavior per the "strict aliasing rules". GCC's -Wstrict-aliasing (included in -Wall) option does not catch all cases, but does attempt to catch the more common pitfalls. So there are cases that GCC does not report but the codes are violating the "strict aliasing rules". Given lots of codes that may be written to rely on "type-punning", and Linux kernel disables it by -fno-strict-aliasing globally, since U-Boot currently does this on nds32/riscv/x86 builds only, extend this for all architecture builds.

2018-08-20Makefile: Don't generate position independent codeAndy Shevchenko
Since gcc-8 the --enable-default-pie starts producing code which assembler can't translate in case of U-Boot. The build fails with {standard input}: Assembler messages: {standard input}:21100: Error: junk at end of line, first unrecognized character is `@' {standard input}:21120: Error: junk at end of line, first unrecognized character is `@' and so on. This is usually the case for x86 platform because in many cases it uses host compiler from the Linux distributions, where PIE is enabled by default. Previously (gcc-7 and earlier) that was a potential issue due to absence of constructions like .long end.5561@gotoff-start.5558@gotoff which are a cause of above error messages in gcc-8. Fix all these by disabling PIE on Makefile level.

2018-07-23doc: Replace DocBook with sphinx-based docsMario Six
The Linux kernel moved to sphinx-based documentation and got rid of the DocBook based documentation quite a while ago. Hence, the DocBook documentation for U-Boot should be converted as well. To achieve this, import the necessary files from Linux v4.17, and convert the current DocBook documentation (three files altogether) to sphinx/reStructuredText. For now, all old DocBook documentation was merged into a single handbook, tentatively named "U-Boot Hacker Manual". For some source files, the documentation style was changed to comply with kernel-doc; no functional changes were applied. Signed-off-by: Mario Six <mario.six@gdsys.cc>

2018-05-31kconfig: re-sync with Linux 4.17-rc4Eugeniu Rosca
Align Kconfig to Linux 4.17-rc4 with minimal impact on non-kconfig files. Previous Kconfig sync was done by commit bf7ab1e70fd762 ("kconfig: re-sync with Linux 4.10") and it achieved almost perfect alignment with a few (intended) exceptions, caused by below U-boot commits: [A] v2015.04 5f9eb2207500 ("kbuild: remove scripts/multiconfig.sh") [B] v2015.07 20c20826efab ("Kconfig: Enable usage of escape char '\' in string values") [C] v2016.01 da58dec86616 ("Various Makefiles: Add SPDX-License-Identifier tags") [D] v2016.03 5b8031ccb4ed ("Add more SPDX-License-Identifier tags") [E] v2016.03 192bc6948b02 ("Fix GCC format-security errors and convert sprintfs.") Here is the list of Kconfig commits which followed the v4.10 alignment: [F] v2018.01 0931ed3c0d0f ("kconfig/symbol.c: use correct pointer type argument for sizeof") [G] v2018.03 1414e09b4f25 ("kconfig: revert change that was not needed for -Wformat-security") [H] v2018.05 83d290c56fab ("SPDX: Convert all of our single license tags to Linux Kernel style") Commit [F] was subsequently applied to Linux kernel as commit [I] with the same patch id, so it won't contribute to further misalignment. [I] v4.15-rc1 88127dae6ed9 ("kconfig/symbol.c: use correct pointer type argument for sizeof") Commit [G] is a Kconfig-specific revert of commit [E]. Commit [H] relocated and reformatted the license doing no functional change. In summary, the only functional change that makes U-boot Kconfig diverge from Linux Kconfig is commit [B]. After a brief analysis, the purpose of [B] seems to be placing "\n" literals in string symbols like CONFIG_AUTOBOOT_PROMPT="autoboot in %d seconds\n" in order to pass them directly to printf and expect correct output at runtime. Currently, Linux doesn't seem to have this requirement, so for the moment [B] looks like a U-boot specific feature/fix. From point of view of further Kconfig alignment and backporting efforts, it is highly desired that commits like [B] are propagated to Linux and any Kconfig fixes/features are contributed to Linux kernel first. This specific Kconfig re-sync just keeps [B] in place. Contrary to 4.10 Kconfig re-sync (which achieves zero non-kconfig changes), 4.17-rc4 re-sync does some amount of updates in Kbuild (striving to keep them at minimum), due to a number of reasons: * Kbuild is affected by the removal of Kconfig "*shipped" files and now requires flex and bison pre-installed on the host. * PYTHON{2,3} variables are defined in top-level Makefile as prerequisite for running the newly developed Kconfig unit tests. * silentoldconfig becomes an "internal implementation detail" deprecated for external use, being renamed to syncconfig. The exact non-kconfig files touched by this commit are: $ git show --format="" --stat -- ':!scripts/kconfig' .gitignore | 2 ++ Makefile | 9 +++++++-- scripts/Makefile.build | 11 +++++++++++ scripts/Makefile.lib | 41 ++++++++++++----------------------------- The imported Linux commits touching the above files are: c054be10ffdbd5 ("remove gperf left-overs from build system") 73a4f6dbe70a1b ("kbuild: add LEX and YACC variables") 033dba2ec06c47 ("kbuild: prepare to remove C files pre-generated by flex and bison") eea199b445f64c ("kbuild: remove unnecessary LEX_PREFIX and YACC_PREFIX") e71de5ee08dcb0 ("kbuild: remove remaining use of undefined YACC_PREFIX") d59fbbd09d5d6b ("kbuild: replace hardcoded bison in cmd_bison_h with $(YACC)") 911a91c39cabcb H ("kconfig: rename silentoldconfig to syncconfig") 59889300274569 (".gitignore: move *.lex.c *.tab.[ch] patterns to the top-level .gitignore") 9a8dfb394c0467 ("kbuild: clean up *.lex.c and *.tab.[ch] patterns from top-level Makefile") 833e622459432e H ("genksyms: generate lexer and parser during build instead of shipping") b23d1a241f4eb4 H ("kbuild: add %.lex.c and %.tab.[ch] to 'targets' automatically") e9781b52d4e0e3 H ("kbuild: add PYTHON2 and PYTHON3 variables") The commits marked with 'H' are assessed as "hard" (build will fail) prerequisites and the rest of them are assessed as "soft" prerequisites for the re-sync. In spite of relatively high number of non-H commits, they belong to this Kconfig update topic-wise and decrease the number of cherry pick conflicts for many commits in this series. Additional effort can be put in eliminating the soft prerequisites, if really needed. The commits which contributed to this Kconfig re-sync are listed below.

A similar problem has been reported for genksyms parser in v4.17-rc1 commit 833e622459432e ("genksyms: generate lexer and parser during build instead of shipping"). I have figured out empirically that the warnings are healed after updating the in-tree U-boot DTC to upstream v1.4.6-9, same as done by Linux v4.17-rc1 commit 9130ba88464032 ("scripts/dtc: Update to upstream version v1.4.6-9-gaadd0b65c987"). Whether fixing the DTC-related yacc warnings should be done together with the Kconfig re-sync, I would like to hear from community.

2018-05-23Makefile: adopt --std=gnu11 for HOSTCFLAGS on LinuxPhilipp Tomsich
Following the conversion of the SPDX license tags, a number of files compiled with -pedantic now generate warnings similar to the following for using C99-style '//' comments in ISO C90 code: tools/gen_eth_addr.c:1:1: warning: C++ style comments are not allowed in ISO C90 // SPDX-License-Identifier: GPL-2.0+ ^ The SPDX comment-style change means that these files have adopted C99, so need to change the language-standard to --std=gnu99 or --std=gnu11 to let the compiler know this. As we now require GCC 6 or newer for the cross-compiler, the project has implicitly moved the project to GNU11: let older GCC versions on various Linux distros know to treat our host tools as GNU11 as well.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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>

2018-04-28kbuild: use -fmacro-prefix-map to make __FILE__ a relative pathMasahiro Yamada
The __FILE__ macro is used everywhere in U-Boot to locate the file printing the log message, such as WARN_ON(), etc. If U-Boot is built out of tree, this can be a long absolute path. This is because Kbuild runs in the objtree instead of the srctree, then __FILE__ is expanded to a file path prefixed with $(srctree)/. A brand-new option from GCC, -fmacro-prefix-map, solves this problem. If your compiler supports it, __FILE__ is the relative path from the srctree regardless of O= option. This provides more readable log, more reproducible builds, and smaller image size.
