The exported sub_make_done variable leaks into the environment of all
child processes. When make targets like tcheck spawn independent make
invocations with O=, those child makes inherit sub_make_done=1, skip
the KBUILD_OUTPUT setup and try to build in the source tree.
There is a workaround that resets sub_make_done to 0 for specific test
targets, but this isn't great since it has tolist every target that
spawns independent make invocations.
Instead, unexport sub_make_done once we are in the final make
invocation. The direct sub-make already has the value in its
environment from the export, and no further propagation is needed.
This also allows the per-target workaround to be removed.
Fixes: 27529f1cb02d ("kbuild: skip parsing pre sub-make code for recursion")

Our last sync with the kernel was 5.1.
We are so out of sync now, that tracking the patches and backporting
them one by one makes little sense and it's going to take ages.
This is an attempt to sync up Makefiles to 6.1.
Unfortunately due to sheer amount of patches this is not easy to review,
but that's what we decided during a community call for the bump to 5.1,
so we are following the same guidelines here.

CROSS_COMPILE handling"
Dmitrii Sharshakov <d3dx12.xx@gmail.com> says:
Initially fix the inconsistency reported in reply to the previous
series and also make sure AArch64 images can be built with latest
Clang versions by guarding AArch32-specific options behind extra
config checks.
Tested qemu_arm_defconfig and qemu_arm64_defconfig with Clang 21,
mainline (to be 22) ce7f9f9c and also Clang 18 (for AArch64 only, as I
have not managed to build an AArch32 image with clang-18).

Clang cross-compilation worked when cross binutils were available
in PATH. However, when binutils are not in the PATH clang failed to
discover the assembler, falling back to host one.
Make --prefix always absolute, Clang supports this and will search for
e.g. $(prefix)-as for assembler. This makes sure user does not have to
add cross binutils to PATH for Clang build.
Fixes build for these examples (with qemu_arm(64)_defconfig):
make CC=clang-21 CROSS_COMPILE=/.../bin/arm-none-eabi-
make CC=clang-20 CROSS_COMPILE=/.../bin/aarch64-linux-gnu-
Also validated for the case when provided with cross toolchain on PATH:
PATH=/.../bin:$PATH make CC=clang-21 CROSS_COMPILE=arm-none-eabi- -j20
This patch does not affect GCC builds, and they have _not_ been
validated against regressions.

This patch adds creation of tifalcon.bin for the AM62a, 62p and 62x.
The contents are the same as the existing tispl.bin but A53's SPL and
the FDT have been removed as they are not needed in R5 falcon mode.
This reduces boot time since the payload size is smaller compared to the
regular tispl.bin.

Since the Kbuild bump to 5.1 and specifically
commit af1a9935708a ("kbuild: make -r/-R effective in top Makefile for old Make versions")
the recursion rules have changed.
'make O=/output/dir/' as well as './test/py/test.py --bd sandbox --build'
is working fine but anything that recursively called the makefile was
failing e.g 'make tests', 'make qcheck' etc, which calls a bash script
that ends up calling the makefile again.
The reason is that the internal 'sub_make_done' variable of the makefile
was set after the first pass and the output dir was never evaluated
properly. Reset the variable value if we are executing any of these
tests.

container.cfg and imximage.cfg are used to created .cfgout files that

The different "make" processes share common scripts/Makefile.build
and scripts/Makefile.libs but since they are separate processes
the Makefile rules can't add a dependency from lib/uefi_loader targets
to arch/$(ARCH)/lib/lib.a. Or the file level dependency can be added but
then "make" produces a too sparse error message which does not mention
that one of the dependencies like arch/$(ARCH)/lib/lib.a was not found:
make[3]: *** No rule to make target 'lib/efi_loader/helloworld.efi', needed by '__build'. Stop.
Fix this dependency problem by building arch/$(ARCH)/lib before lib
if CONFIG_USE_PRIVATE_LIBGCC was enabled.
To reproduce the race condition more reliably, add a "sleep 10" delay
before linker command cmd_link_l_target with 2025.07
or to $(lib-target): target in scripts/Makefile.build with master branch
after Kbuild update.

This directory was created when U-Boot gained the ability to run as an
EFI app in 2015. Since then the EFI-loader feature has been added.
The code in lib/efi is not actually used by the loader, so the name is
confusing.

just for U-Boot being a client of EFI, i.e. the EFI app and stub.

Stranges errors are observed when building U-Boot master for almost any
RISC-V board, the messages are in two types, one is about duplicated
symbols,
u-boot/arch/riscv/cpu//mtrap.S:32: multiple definition of `trap_entry';
arch/riscv/cpu/mtrap.o: u-boot/arch/riscv/cpu//mtrap.S:32: first defined here
and the other is fixdep's complaint about missing dependency files,
fixdep: error opening file: arch/riscv/cpu/.mtrap.o.d: No such file or directory
fixdep: error opening file: arch/riscv/cpu//.start.o.d: No such file or directory
where the latter could only be reproduced when building parallelly.
Both the two types of errors are about files in arch/riscv/cpu, and
there's a suspicious slash character in the reported path. Looking
through RISC-V-specific Makefiles, there's only one place that may
expand to such a path,
libs-y += arch/riscv/cpu/$(CPU)/
The right hand expands to "arch/riscv/cpu//" if $(CPU) isn't defined at
the time of including. With some debug statement added to
arch/riscv/Makefile, the output proves that arch/riscv/Makefile is
included twice, once with $(CPU) undefined and once defined correctly
according to CONFIG_SYS_CPU.
Futher bisecting shows an extra include statement against
arch/$(SRCARCH)/Makefile is added in earlier bump of Kbuild system. But
the statement is evaluated before config.mk is included and definition
of $(CPU), causing objects in arch/riscv/cpu/ are built and linked twice
(once as "arch/riscv/cpu/*", and once as "arch/riscv/cpu//*"), resulting
in the error.
Let's simply remove the extra include to fix these nasty errors. For
config targets, bumping Kbuild also introduced a new include to
arch/$(SRCARCH)/Makefile, which is removed as well for consistency.

Our last sync with the kernel was 5.1. Even that was a partial one
as some patches from 4.x kernels were already missing making the
transition to a modern kbuild infeasible.
We are so out of sync now, that tracking the patches and backporting
them one by one makes little sense and it's going to take ages.
This is an attempt to sync up Makefile[.lib/.kbuild].
Unfortunately due to sheer amount of patches this is not easy to review,
but that's what we decided during a community call.
One of the biggest changes is get rid of partial linking entirely and
build .a archives isntead of .o.
We diaviate from the kernel on that. Instead of calling a custom script
to create the archive symbol table, we call ar with rcTP (isntead of
rcSTP) since we want a resulting archive that's sauble with the linker.
The only affected platforms are PPC ones. Unfortunately I don't have any
of them around to test, but the objdump of the resulting files --
arch/powerpc/lib/built-in.[oa] looks identical.
