sandbox: Call bootm_final()

2026-03-18T19:17:34+00:00

Add a call to bootm_final() before the simulated kernel jump. This
adds the "Starting kernel" message, bootstage tracking,
board_quiesce_devices() and dm_remove_devices_active() which were not
previously called on sandbox.

Merge patch series "Switch to using $(PHASE_) in Makefiles"

2025-04-11T18:16:49+00:00

Tom Rini  says:

This series switches to always using $(PHASE_) in Makefiles when
building rather than $(PHASE_) or $(XPL_). It also starts on documenting
this part of the build, but as a follow-up we need to rename
doc/develop/spl.rst and expand on explaining things a bit.

Kbuild: Always use $(PHASE_)

2025-04-11T18:16:44+00:00

It is confusing to have both "$(PHASE_)" and "$(XPL_)" be used in our
Makefiles as part of the macros to determine when to do something in our
Makefiles based on what phase of the build we are in. For consistency,
bring this down to a single macro and use "$(PHASE_)" only.

boot: arm: riscv: sandbox: Add a format for the booti file

2025-03-18T19:12:15+00:00

Arm invented a new format for arm64 and something similar is also used
with RISC-V. Add this to the list of supported formats and provide a way
for the format to be detected on both architectures.

Update the genimg_get_format() function to support this.

Fix up switch() statements which don't currently mention this format.
Booti does not support a ramdisk, so this can be ignored.

acpi: x86: Move MADT to common code

2024-10-27T23:12:44+00:00

Write MADT in common code and let the SoC fill out the body by
calling acpi_fill_madt() which must be implemented at SoC level.

acpi: x86: Write FADT in common code

2024-10-27T23:12:44+00:00

Write the FADT in common code since it's used on all architectures.
Since the FADT is mandatory all SoCs or mainboards must implement the
introduced function acpi_fill_fadt() and properly update the FADT.

sandbox: cleanup linker scripts and sections

2024-07-03T06:36:33+00:00

commit 6e2228fb052b ("Merge patch series "Clean up arm linker scripts"")
was cleaning up linker scripts for armv7 and v8 in a similar fashion.

Several commits in the past -- e.g
commit d0b5d9da5de2 ("arm: make _end compiler-generated")
was moving symbols to be compiler generated. They were defined as c
variables in its own section to force the compiler emit relative a
reference. However, defining those in the linker script will do the
same thing since [0].

So let's remove the special sections from the linker scripts, the
variable definitions from sections.c, and define them as a symbols.
It's worth noting that the linker was discarding the symbols in the
older binary completely since the symbol definition had an extra _.

As reported by Jonas Karlman this series breaks booting on some AArch64
platforms with common use cases. For now the best path forward is to
revert the series.

This reverts commit 777c28460947371ada40868dc994dfe8537d7115, reversing
