arm: Call bootm_final()

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

The ARM announce_and_cleanup() duplicates the common pre-boot steps.
Replace it with a call to bootm_final().

Drop the ARM weak board_quiesce_devices() definition since it is now
called from bootm_final() and the generic weak definition in bootm.h
is used instead.

Note that the printf() ordering changes slightly: it now prints before
bootstage processing rather than after, matching x86 and RISC-V.

ARM: bootm: Add support for starting Linux through OPTEE-OS on ARMv7a

2025-11-06T17:26:18+00:00

Add support for jumping to Linux kernel through OPTEE-OS on ARMv7a.
This is only supported if U-Boot runs in PL1 secure. This change adds
two components, one is fitImage OPTEE-OS loadable handler, which makes
a note of OPTEE-OS being loaded and stores the load address for later
jump to it. The second part is the actual jump to Linux through OPTEE-OS.
The jump through OPTEE-OS requires set up of multiple CPU registers, r1
and r2 are passed through, r0 and r3 have to be set to 0, lr is set to
Linux kernel entry point. This setup is done by new assembler function
boot_jump_linux_via_optee().

The boot_jump_linux_via_optee() also includes STM32MP13xx late TZC
configuration write, this cannot be moved easily, hence the ifdef.

bootstage: stash boot records to reserved mem before kernel handoff

2025-09-26T22:48:10+00:00

U-Boot now stashes its bootstage buffer into a reserved memory region
whenever CONFIG_BOOTSTAGE_STASH is enabled, just before exiting to the
kernel. This allows a post boot parser to read a unified timeline
(SPL→U-Boot→Kernel→MCU/DSP) directly from DDR, enabling standardized
and repeatable boot-time profiling across releases and SoCs.

Change summary:
 Call bootstage_stash_default() in announce_and_cleanup()
  when CONFIG_BOOTSTAGE_STASH is set.

dm: Add dm_remove_devices_active() for ordered device removal

2024-11-24T21:41:28+00:00

This replaces dm_remove_devices_flags() calls in all boot
implementations to ensure non vital devices are consistently removed
first. All boot implementation except arch/arm/lib/bootm.c currently
just call dm_remove_devices_flags(DM_REMOVE_ACTIVE_ALL). This can result
in crashes when dependencies between devices exists. The driver model's
design document describes DM_FLAG_VITAL as "indicates that the device is
'vital' to the operation of other devices". Device removal at boot
should follow this.

Instead of adding dm_remove_devices_flags() with (DM_REMOVE_ACTIVE_ALL |
DM_REMOVE_NON_VITAL) everywhere add dm_remove_devices_active() which
does this.

Fixes a NULL pointer deref in the apple dart IOMMU driver during EFI
boot. The xhci-pci (driver which depends on the IOMMU to work) removes
its mapping on removal. This explodes when the IOMMU device was removed
first.

dm_remove_devices_flags() is kept since it is used for testing of
device_remove() calls in dm.

Adjust boot_os_fn to use struct bootm_info instead of the separate
argc, argv and image parameters. Update the handlers accordingly. Few
of the functions make use of the arguments, so this improves code size
slightly.
