bloblist: add API for applying blobs with specified tag

2026-04-27T15:42:36Z

Add an API to search for the blobs with specified tag and use the hook function to apply the blob data. Add a helper function to return the inline header size as according to recent spec[1] updates, the actual data can be following an inline header instead of following the TE header immediately.

Merge patch series "bloblist: refactor xferlist and bloblist"

2025-02-20T00:49:47Z

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. Link: https://lore.kernel.org/r/20250220000223.1044376-1-raymond.mao@linaro.org

bloblist: kconfig for mandatory incoming standard passage

2025-02-20T00:49:36Z

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. Signed-off-by: Raymond Mao

bloblist: refactor xferlist and bloblist

2025-02-20T00:49:36Z

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. Signed-off-by: Raymond Mao Suggested-by: Ilias Apalodimas

Merge patch series "Enable bloblist support on Vexpress64"

2025-02-12T00:09:05Z

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 api to get blob with size

2025-01-28T06:59:21Z

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.

arm: cpu: Add ACPI parking protocol support

2024-10-27T23:24:13Z

On Arm platforms that use ACPI they cannot rely on the "spin-table" CPU bringup usually defined in the FDT. Thus implement the 'ACPI Multi-processor Startup for ARM Platforms', also referred to as 'ACPI parking protocol'. The ACPI parking protocol works similar to the spin-table mechanism, but the specification also covers lots of shortcomings of the spin-table implementations. Every CPU defined in the ACPI MADT table has it's own 4K page where the spinloop code and the OS mailbox resides. When selected the U-Boot board code must make sure that the secondary CPUs enter u-boot after relocation as well, so that they can enter the spinloop code residing in the ACPI parking protocol pages. The OS will then write to the mailbox and generate an IPI to release the CPUs from the spinloop code. For now it's only implemented on ARMv8, but can easily be extended to other platforms, like ARMv7.
