riscv: Call bootm_final()

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

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

Move board_quiesce_devices() into bootm_final() so it is available to
all architectures. Drop the RISC-V weak definition and header
declaration since the generic one in bootm.h is used instead.

booti/bootm: riscv: Verify image arch type

2025-05-21T08:45:56+00:00

Unlike ARM and X86, booting 32-bit images on 64-bit CPUs is currently
not supported for Risc-V. Hence, for bootm, disallow booting a FIT
or a legacy image that was built for an arch type which is different
than the current arch and for booti, set the arch type to be the
same as the current arch.

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.

lmb: do away with arch_lmb_reserve()

2024-09-03T20:08:50+00:00

All of the current definitions of arch_lmb_reserve() are doing the
same thing -- reserve the region of memory occupied by U-Boot,
starting from the current stack address to the ram_top. Introduce a
function lmb_reserve_uboot_region() which does this, and do away with
the arch_lmb_reserve() function.

Instead of using the current value of stack pointer for starting the
reserved region, have a fixed value, considering the stack size config
value.

lmb: make LMB memory map persistent and global

2024-09-03T20:08:50+00:00

The current LMB API's for allocating and reserving memory use a
per-caller based memory view. Memory allocated by a caller can then be
overwritten by another caller. Make these allocations and reservations
persistent using the alloced list data structure.

Two alloced lists are declared -- one for the available(free) memory,
and one for the used memory. Once full, the list can then be extended
at runtime.

bootm: Adjust arguments of boot_os_fn

2023-12-21T21:07:52+00:00

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.
