ebe3c3c4a8 x86: Stop working around skip-at-start
With a recent Binman change, the skip-at-start property is now honoured,
meaning that all image-pos values in the affected section start from
the skip-at-start value.

The x86 code works around the old behaviour at present, so update it.

5a7e8839e4 x86: Align the SMBIOS table to a 4K boundary
This isn't strictly needed, but with UPL we use the reserved-memory
nodes to indicate where the SMBIOS table is. Tianocore requires 4KB
alignment on these regions, so it is easier to adjust the alignment
to match.

53d5a22163 emulation: Use bloblist to hold tables
QEMU can have its own internal ACPI and SMBIOS tables. At present U-Boot
copies out the SMBIOS tables but points directly to the ACPI ones.

The ACPI tables are not aligned on a 4KB boundary, which means that UPL
cannot use them directly, since it uses a reserved-memory node for the
tables and that it assumed (by EDK2) to be 4KB-aligned.

On x86, QEMU provides the tables in a mapped memory region and U-Boot
makes use of these directly, thus making it difficult to use any common
code.

Adjust the logic to fit within the existing table-generation code. Use a
bloblist always and ensure that the ACPI tables is placed in an aligned
region. Set a size of 8K for QEMU. This does not actually put all the
tables in one place, for QEMU, since it currently adds a pointer to the
tables in QFW.

On ARM, enable bloblist so that SMBIOS tables can be added to the
bloblist.

dabaa4ae32 dm: Add dm_remove_devices_active() for ordered device removal
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.

2800aecce0 Merge patch series "Implement ACPI on aarch64"
Patrick Rudolph <patrick.rudolph@9elements.com> says:

Based on the existing work done by Simon Glass this series adds
support for booting aarch64 devices using ACPI only.
As first target QEMU SBSA support is added, which relies on ACPI
only to boot an OS. As secondary target the Raspberry Pi4 was used,
which is broadly available and allows easy testing of the proposed
solution.

The series is split into ACPI cleanups and code movements, adding
Arm specific ACPI tables and finally SoC and mainboard related
changes to boot a Linux on the QEMU SBSA and RPi4. Currently only the
mandatory ACPI tables are supported, allowing to boot into Linux
without errors.

The QEMU SBSA support is feature complete and provides the same
functionality as the EDK2 implementation.

The changes were tested on real hardware as well on QEMU v9.0:

qemu-system-aarch64 -machine sbsa-ref -nographic -cpu cortex-a57 \
                    -pflash secure-world.rom \
                    -pflash unsecure-world.rom

qemu-system-aarch64 -machine raspi4b -kernel u-boot.bin -cpu cortex-a72 \
-smp 4 -m 2G -drive file=raspbian.img,format=raw,index=0 \
-dtb bcm2711-rpi-4-b.dtb -nographic

Tested against FWTS V24.03.00.

Known issues:
- The QEMU rpi4 support is currently limited as it doesn't emulate PCI,
  USB or ethernet devices!
- The SMP bringup doesn't work on RPi4, but works in QEMU (Possibly
  cache related).
- PCI on RPI4 isn't working on real hardware since the pcie_brcmstb
  Linux kernel module doesn't support ACPI yet.

360aaddd9c Merge patch series "Make LMB memory map global and persistent"
Sughosh Ganu <sughosh.ganu@linaro.org> says:

This is a follow-up from an earlier RFC series [1] for making the LMB
and EFI memory allocations work together. This is a non-rfc version
with only the LMB part of the patches, for making the LMB memory map
global and persistent.

This is part one of a set of patches which aim to have the LMB and EFI
memory allocations work together. This requires making the LMB memory
map global and persistent, instead of having local, caller specific
maps. This is being done keeping in mind the usage of LMB memory by
platforms where the same memory region can be used to load multiple
different images. What is not allowed is to overwrite memory that has
been allocated by the other module, currently the EFI memory
module. This is being achieved by introducing a new flag,
LMB_NOOVERWRITE, which represents memory which cannot be re-requested
once allocated.

The data structures (alloced lists) required for maintaining the LMB
map are initialised during board init. The LMB module is enabled by
default for the main U-Boot image, while it needs to be enabled for
SPL. This version also uses a stack implementation, as suggested by
Simon Glass to temporarily store the lmb structure instance which is
used during normal operation when running lmb tests. This does away
with the need to run the lmb tests separately.

The tests have been tweaked where needed because of these changes.

The second part of the patches, to be sent subsequently, would work on
having the EFI allocations work with the LMB API's.

[1] - https://lore.kernel.org/u-boot/20240704073544.670249-1-sughosh.ganu@linaro.org/T/#t

Notes:

1) These patches are on next, as the alist patches have been
   applied to that branch.
2) I have tested the boot on the ST DK2 board, but it would be good to
   get a T-b/R-b from the ST maintainers.
3) It will be good to test these changes on a PowerPC platform
   (ideally an 85xx, as I do not have one).

    00000000000f0074  eb9d2d31-2d88-11d3-9a16-0090273fc14d  SMBIOS table

The SMBIOS configuration table does not point to a paragraph-aligned
(16 byte aligned) address. The reason is that in write_tables() rom_addr is
not aligned and copied to gd->arch.smbios_start.

The Simple Firmware Interface requires that the SFI table is paragraph-
aligned but our code does not guarantee this.

As all tables written in write_tables() must be paragraph-aligned, we
should implement the address rounding in write_tables() and not in table
specific routines like copy_pirq_routing_table().

Add paragraph-alignment in write_tables().

bade0ac04b x86: zboot: Move command code into its own file
Much of the code in zimage.c deals with the zboot command. Move it into
a sepatate zboot.c file within the cmd/ directory. This will eventually
allow use of the zimage logic without the command being enabled.

e4255f45c9 x86: zboot: Move zimage definitions to the header file
In preparation for splitting the zboot-command code into a separate
file, move the definitions into the header file.

While we are here, mention when load_address and base_ptr are set up
and explain bzimage_addr better. Make cmdline const since it cannot be
changed.
