bloblist: use correct types for physical addresses

2025-09-12T19:49:34+00:00

It is expected that bloblists are stored in high memory beyond 2 GiB.
We must not use int as data type for these addresses but phys_addr_t.

Merge patch series "bloblist: refactor xferlist and bloblist"

2025-02-20T00:49:47+00:00

Tom Rini  says:

This small series separates "bloblist" and "standard passage" to allow
for these similar concepts to explore solutions to problems without
introduces breaking changes to the other.

bloblist: kconfig for mandatory incoming standard passage

2025-02-20T00:49:36+00:00

In previous commit, incoming standard passage is used by default
when initializing the bloblist, so explicitly BLOBLIST_PASSAGE is
no more needed.
Rename it as BLOBLIST_PASSAGE_MANDATORY to determine the behaviors
when an incoming transfer list does not exist or is invalid.
When it is selected, incoming standard passage is mandatory and
U-Boot will report an error when a valid incoming transfer list is
missing.

bloblist: refactor xferlist and bloblist

2025-02-20T00:49:36+00:00

Refactor the xferlist to remove the relocating when bloblist passed
from the boot args.
Refactor bloblist init to use incoming standard passage by default
if a valid transfer list exists in the boot args.
For bloblist relocation, use the actual total size if it has a smaller
BLOBLIST_SIZE_RELOC.

Merge patch series "Enable bloblist support on Vexpress64"

2025-02-12T00:09:05+00:00

Harrison Mutai  says:

This series of patches enhances the vexpress64 platform by enabling bloblist
support. It also introduces support for CONFIG_BLOBLIST_PASSAGE. This is
necessary to boot vexpress64 and other boards without manually specifying a
fixed address and size for the bloblist.

After this change, all the bloblist init modes are supported (i.e., fixed,
alloc, passage) and Vexpress64 boots with CONFIG_BLOBLIST_PASSAGE.

bloblist: add support for CONFIG_BLOBLIST_PASSAGE

2025-02-12T00:08:58+00:00

When the configuration option CONFIG_BLOBLIST_PASSAGE is selected, the
bloblist present in the incoming standard passage is utilised in-place.
There is no need to specify the size of the bloblist as the system
automatically detects it using the header information.

bloblist: add api to get blob with size

2025-01-28T06:59:21+00:00

bloblist_find function only returns the pointer of blob data,
which is fine for those self-describing data like FDT.
But as a common scenario, an interface is needed to retrieve both
the pointer and the size of the blob data.

Add a few ut test cases for the new api.

x86: select CONFIG_64BIT for X86_64

2024-12-31T16:58:30+00:00

Select CONFIG_64BIT so that we pass the -m64 option (instead of -m32) to
static analysis tools.
Introduce CONFIG_SPL_64BIT and select it for architectures other than
x86 with 64 bit builds. Do not select it for x86 builds as x86 uses
a 32 bit SPL.
Ensure that when limits are set they use CONFIG_64BIT for U-Boot
proper and CONFIG_SPL_64BIT for SPL. This is to allow for the 32 bit
SPL build used by x86.

Merge patch series "Implement ACPI on aarch64"

2024-10-28T00:44:13+00:00

Patrick Rudolph  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.
