2023-08-29scripts/Makefile.lib: Embed capsule public key in platform's dtbSughosh Ganu
The EFI capsule authentication logic in u-boot expects the public key in the form of an EFI Signature List(ESL) to be provided as part of the platform's dtb. Currently, the embedding of the ESL file into the dtb needs to be done manually. Add a target for generating a dtsi file which contains the signature node with the ESL file included as a property under the signature node. Include the dtsi file in the dtb. This brings the embedding of the ESL in the dtb into the U-Boot build flow. The path to the ESL file is specified through the CONFIG_EFI_CAPSULE_ESL_FILE symbol.

2023-05-31scripts/Makefile.lib: change spelling of $(srctree)/arch/$(ARCH)/dts in ↵Rasmus Villemoes
dtc_cpp_flags Currently, all in-tree .dts files (apart from some under test/ and tools/), reside in arch/$ARCH/dts. However, in the linux kernel tree, dts files for arm64 boards, and probably in the not too distant future [1], arm boards as well, live in subdirectories of that. For private forks, using a vendor or project subdirectory is also more convenient to clearly separate private code from upstream - in the same way that code under board/ is also split and easy to maintain. In order to prepare for us to follow suit and do the splitting of the in-tree .dts files, and to make life a little easier for private forks that already place dts files not directly in arch/$ARCH/dts, change the $(srctree)/arch/$(ARCH)/dts path to instead refer to the directory of the .dts file being compiled. This should be a no-op for all existing cases. [1] https://lore.kernel.org/lkml/20220328000915.15041-1-ansuelsmth@gmail.com/ Signed-off-by: Rasmus Villemoes <rasmus.villemoes@prevas.dk>
2023-05-15kbuild: Allow DTB overlays to built from .dtso named source filesRasmus Villemoes
[Linux commit 363547d2191c] Currently DTB Overlays (.dtbo) are build from source files with the same extension (.dts) as the base DTs (.dtb). This may become confusing and even lead to wrong results. For example, a composite DTB (created from a base DTB and a set of overlays) might have the same name as one of the overlays that create it. Different files should be generated from differently named sources. .dtb <-> .dts .dtbo <-> .dtso We do not remove the ability to compile DTBO files from .dts files here, only add a new rule allowing the .dtso file name. The current .dts named overlays can be renamed with time. After all have been renamed we can remove the other rule. [Import notes: Adapt to U-Boot by using the cmd_dtco function instead of cmd_dtc just like the current .dts -> .dtbo rule.] Signed-off-by: Rasmus Villemoes <rasmus.villemoes@prevas.dk> Reviewed-by: Simon Glass <sjg@chromium.org>

We borrow from the Linux Kernel 0d362be5b142 ("Makefile: link with -z noexecstack --no-warn-rwx-segments") here to disable the RWX segment linking warnings. We do not also bring in -z noexecstack as that requires auditing and using ".note.GNU-stack" on assembly functions which do need this feature. Further, we now introduce KBUILD_EFILDFLAGS so that we can also pass --no-warn-rwx-segments when linking EFI applications, and those do explicitly pass -z execstack.

2022-01-25introduce CONFIG_DEVICE_TREE_INCLUDESRasmus Villemoes
The build system already automatically looks for and includes an in-tree *-u-boot.dtsi when building the control .dtb. However, there are some things that are awkward to maintain in such an in-tree file, most notably the metadata associated to public keys used for verified boot. The only "official" API to get that metadata into the .dtb is via mkimage, as a side effect of building an actual signed image. But there are multiple problems with that. First of all, the final U-Boot (be it U-Boot proper or an SPL) image is built based on a binary image, the .dtb, and possibly some other binary artifacts. So modifying the .dtb after the build requires the meta-buildsystem (Yocto, buildroot, whatnot) to know about and repeat some of the steps that are already known to and handled by U-Boot's build system, resulting in needless duplication of code. It's also somewhat annoying and inconsistent to have a .dtb file in the build folder which is not generated by the command listed in the corresponding .cmd file (that of course applies to any generated file). So the contents of the /signature node really needs to be baked into the .dtb file when it is first created, which means providing the relevant data in the form of a .dtsi file. One could in theory put that data into the *-u-boot.dtsi file, but it's more convenient to be able to provide it externally: For example, when developing for a customer, it's common to use a set of dummy keys for development, while the consultants do not (and should not) have access to the actual keys used in production. For such a setup, it's easier if the keys used are chosen via the meta-buildsystem and the path(s) patched in during the configure step. And of course, nothing prevents anybody from having DEVICE_TREE_INCLUDES point at files maintained in git, or for that matter from including the public key metadata in the *-u-boot.dtsi directly and ignore this feature. There are other uses for this, e.g. in combination with ENV_IMPORT_FDT it can be used for providing the contents of the /config/environment node, so I don't want to tie this exclusively to use for verified boot.

2022-01-25acpi: Allow include files within the board directorySimon Glass
Some .asl files include others using the iasl 'include' directive. This needs to be able to find the files referenced. For an out-of-tree build the source directory is not the current directory. Moreover, U-Boot preprocesses the input file and puts the result in the output directory. So iasl does not know where the real source file came from. Add a -I option to produce the correct behaviour. We could add an option to not preprocess the .asl source, but for now that seems unnecessary. Signed-off-by: Simon Glass <sjg@chromium.org>

2019-12-15fdt: Show the preprocessed .dts file on errorSimon Glass
When device-tree compilation fails it is sometimes tricky to see which line is broken, since the input file to dtc is a pre-processed version of the device tree. Add a line that points to the file that needs to be checked: When the error is in the main .dts file, output is something like this: output: 'Error: arch/x86/dts/.chromebook_coral.dtb.pre.tmp:478.46-47 syntax error FATAL ERROR: Unable to parse input tree but in fact looking at that file shows nothing useful: PAD_CFG_NF_IOSSTATE_IOSTERM(GPIO_157, UP_20K, DEEP, NF1, HIZCRX1, DISPUPD) Instead we need to look at the preprocessed file, which shows: 163 ((1U << 30) | (1 << 10)) ((0xb << 10) | PAD_CFG1_IOSSTATE_HIZCRX1) Here it is clear that PAD_CFG1_IOSSTATE_HIZCRX1 is not defined and so is not being resolved by the preprocessor. This commit adds an additional useful message: Check arch/x86/dts/.chromebook_coral.dtb.dts.tmp for errors Note that if the error is reported in an included file, such as u-boot.dtsi then the output is the following: Error: arch/x86/dts/u-boot.dtsi:137.14-15 syntax error FATAL ERROR: Unable to parse input tree But again, if the error is due to a preprocessor failure, like this: filename = CONFIG_IFW_INPUT_FILE; then you can't tell what the problem is by looking at the source. All you see is the original code: intel-ifwi { filename = CONFIG_IFW_INPUT_FILE; ... }; }; intel-fsp-m { filename = CONFIG_FSP_FILE_M; }; Everything looks fine. But looking at the output of the preprocessor: intel-ifwi { filename = CONFIG_IFW_INPUT_FILE; ... }; intel-fsp-m { filename = "fsp_m.bin"; }; This shows that the filename (normally "fitimage.bin") has not been inserted the preprocess, leading to the realisation that the value should be CONFIG_IFWI_INPUT_FILE. If the above does not make sense, I encourage people to try introducing errors in the device tree preprocessed values.

2019-08-09x86: Avoid writing temporary asl files into the source treeSimon Glass
At present the iasl tool (Intel ACPI (Advanced Configuration and Power Interface) Source Language Compiler) is called in such a way that it uses the source directory for its temporary files. This means we end up with these files when building x86 boards: board/dfi/dfi-bt700/dsdt.aml board/dfi/dfi-bt700/dsdt.asl.tmp Update the code to put temporary files in the target directory instead.

2019-02-28kbuild: fix DTB .cmd source variableStephen Warren
*.dts are processed using a custom command, then the C pre-processor is run on them, then they are compiled using dtc. Thus, the dependency files generated by both cpp and dtc reference a temporary file name rather than the actual source file. While this information isn't used for any purpose by the build system, and hence this causes no functional issue, it does cause the dependency files to contain invalid and confusing data, which is unhelpful while debugging build problems.

2019-01-15kbuild: add .SECONDARY special target to scripts/Kbuild.includeMasahiro Yamada
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") 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 A couple of makefiles mark 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.

The commit f9a88a4c1cd0 ("iASL: Enhance the -tc option (create AML hex file in C)") in ACPICA project changed a template of the variable that is used in the generated C-file. Now, instead of hard coded "AmlCode" the "%s_aml_code" is in use, where the prefix is a lowered case base name of the output file. In our case it will be "dsdt" producing a name as "dsdt_aml_code". The quick solution is to call sed which replaces new name by the old one to keep compatibility with old version of iASL. The long term solution would be to modify code to use the new name because it is more scalable.

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.

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>

The current makefile logic disables creation of the SPL.log/u-boot-ivt.img.log etc. files when V=1 is given on the command line, the rationale presumably being that the user wants and gets the information on the console. However, from general principles, I don't think a higher V= level should affect which build artifacts get generated (and certainly shouldn't produce fewer). Concretely, it's also a problem that when doing a V=1 build in a terminal, the relevant HAB blocks lines easily drown in all the other V=1 output. Moreover, build systems such as Yocto by default pass V=1, so in that case the information gets hidden away in the do_compile log file, making it nigh impossible to create a recipe for creating signed U-boot images - I don't want to disable V=1, because having verbose output in the log file is valuable when things go wrong, but OTOH trying to go digging in the do_compile log file (and getting exactly the right lines) is not pleasant to even think about. So change the logic so that for V=0, the mkimage output is redirected to MKIMAGEOUTPUT (which is also the current behaviour), while for any other value of V, we _additionally_ write the information to make's stdout, whatever that might be.
