u-boot.git/tools/fwumdata_src/mkfwumdata.c, branch master Unnamed repository; edit this file 'description' to name the repository. tools: mkfwumdata: Remove dependency on fwu_mdata.h header 2026-03-26T06:20:00+00:00 Kory Maincent kory.maincent@bootlin.com 2026-02-23T13:18:40+00:00 44a1e17b2a49d724538b4d500b27b0eda4be015c The dependency on fwu_mdata.h creates unnecessary configuration requirements. To generate metadata V1, CONFIG_FWU_MDATA_V1 must be enabled, which in turn requires enabling FWU_MULTI_BANK_UPDATE, EFI_CAPSULE_ON_DISK, PARTITION_TYPE_GUID, and other unrelated configs. This is not suitable for a simple standalone tool. Additionally, even with the "-v 1" option to generate V1 metadata, the tool will still include the firmware store description if CONFIG_FWU_MDATA_V1 is not enabled. This structure should only be present in metadata V2. Replace the fwu_mdata.h dependency with the new fwumdata header to make the tool compatible with both V1 and V2 without requiring any defconfig changes. This also uses the access helper functions from the header to eliminate code duplication.

The dependency on fwu_mdata.h creates unnecessary configuration
requirements. To generate metadata V1, CONFIG_FWU_MDATA_V1 must be
enabled, which in turn requires enabling FWU_MULTI_BANK_UPDATE,
EFI_CAPSULE_ON_DISK, PARTITION_TYPE_GUID, and other unrelated configs.
This is not suitable for a simple standalone tool.

Additionally, even with the "-v 1" option to generate V1 metadata, the
tool will still include the firmware store description if
CONFIG_FWU_MDATA_V1 is not enabled. This structure should only be
present in metadata V2.

Replace the fwu_mdata.h dependency with the new fwumdata header to make
the tool compatible with both V1 and V2 without requiring any defconfig
changes. This also uses the access helper functions from the header to
eliminate code duplication.

tools: mkfwumdata: Add bank count validation for FWU metadata v2 2026-03-26T06:20:00+00:00 Kory Maincent kory.maincent@bootlin.com 2026-02-23T13:18:38+00:00 e3757929646f102070232efd86d3a308b0f54ec3 The FWU metadata specification version 2 supports a maximum of 4 banks. Add validation to enforce this limit and prevent creation of non-compliant metadata structures when using version 2. Without this check, users could inadvertently create invalid metadata by specifying more than 4 banks, leading to potential compatibility issues with FWU-compliant firmware update implementations.

This refactoring prepares for the addition of the fwumdata runtime tool, which will allow editing FWU metadata directly from the target. The Kconfig and Makefile entries are also moved into separate files within the new directory (Kconfig and fwumdata.mk respectively) to keep all FWU metadata tool configurations together and improve maintainability.
