The defines for the different build phases shouldn't be used in device trees, currently they aren't even defined for device tree pre processing, resulting in build errors.

A problem we have today is that some instances of IS_ENABLED(FOO) have crept in to the code. This is in turn because with checkpatch.pl this is only a warning and not an error, so they were overlooked. And looking deeper, in the Linux kernel this pattern is allowed because IS_ENABLED(DEFINED_FLAG) is allowed if discouraged and a quick skim of the instances I saw in the current kernel follow this pattern. In U-Boot however, this is not allowed, so bump to an error. Signed-off-by: Tom Rini <trini@konsulko.com>
Pull request efi-2025-04-rc1 Documentation: * Correct the defconfig name in the coolpi documentation UEFI: * Carve out the biggest part of the RISC-V and ARM linker scripts for EFI binary into a common include. * Correct the values of SizeOfCode and SizeOfInitializedData in generated EFI binaries for RISC-V and ARM. * Avoid gaps between sections in EFI binaries causing a failure in secure boot. * Makefile: let clean remove capsule_in.capsule*.efi-capsule * Refactor some of the code used for launching EFI binaries.
In case the build system builds a directory with empty Makefile, one which does not contain any obj-y entries, the build fails to link due to missing built-in.o . This happens because of this part of scripts/Makefile.build 81 ifneq ($(strip $(obj-y) $(obj-m) $(obj-) $(subdir-m) $(lib-target)),) 82 builtin-target := $(obj)/built-in.o 83 endif which does not assign builtin-target in case obj-y is empty. The built-in target is then not built at all, and built-in.o is not generated by this part of scripts/Makefile.build 325 ifdef builtin-target 326 quiet_cmd_link_o_target = AR $@ 327 # If the list of objects to link is empty, just create an empty built-in.o ... 335 targets += $(builtin-target) 336 endif # builtin-target This is the correct behavior. The final link however expects the built-in.o to exist in every directory included in the build, even in those where the aforementioned code skipped generation of built-in.o . Make sure the built-in.o does exist for every directory used in final link simply by doing touch on every built-in.o used for the link, which will create empty built-in.o in case any built-in.o is missing. A possible alternative fix is the always define the builtin-target and always generate built-in.o .

The linker uses the path specified with -L to search for linker scripts and for linker script includes. For out-of-tree builds specify the build directory with -L instead of the absolute path of the linker script. This allows using an INCLUDE statement.

Swig has changed language specific AppendOutput functions. The helper macro SWIG_AppendOutput remains unchanged. Use that instead of SWIG_Python_AppendOutput, which would require an extra parameter since swig 4.3.0. /home/flk/poky/build-test/tmp/work/qemux86_64-poky-linux/u-boot/2024.10/git/arch/x86/cpu/u-boot-64.lds | scripts/dtc/pylibfdt/libfdt_wrap.c: In function ‘_wrap_fdt_next_node’: | scripts/dtc/pylibfdt/libfdt_wrap.c:5581:17: error: too few arguments to function ‘SWIG_Python_AppendOutput’ | 5581 | resultobj = SWIG_Python_AppendOutput(resultobj, val); | | ^~~~~~~~~~~~~~~~~~~~~~~~ Signed-off-by: Markus Volk <f_l_k@t-online.de> Reported-by: Rudi Heitbaum <rudi@heitbaum.com> Link: https://github.com/dgibson/dtc/pull/154
