[PATCH 0/7] qcom: Add FIT capsule support with multi-partition updates

[Balaji Selvanathan]

This patch series introduces FIT-based capsule updates alongside the
existing RAW capsule implementation, enabling atomic multi-partition
firmware updates. The implementation automatically discovers all
partitions across SCSI/UFS and eMMC devices, applies A/B slot
selection based on GPT vendor attributes, and generates a single
ESRT entry representing all partitions for simplified management.

The series also improves ESRT reporting by tracking last attempt status
for both FIT and RAW capsules.

Patch 1 adds the core FIT capsule infrastructure with comprehensive
partition discovery, A/B selection logic, and multi-partition DFU
string generation for both UFS and eMMC storage.

Patch 2 implements last attempt status tracking for FIT capsules,
enabling proper ESRT reporting with version and status information.

Patch 3 extends last attempt tracking to RAW capsules for consistent
ESRT behavior across both capsule types.

Patch 4 ensures firmware version extraction even when capsule
authentication fails, improving error reporting accuracy.

Patch 5 switches the default Qualcomm configuration from RAW to FIT
capsule support.

Patch 6 provides fvupdate_to_fit.py, a Python tool for end-to-end
conversion from XML files to deployable capsules,
with support for board-specific GUIDs, versioning, and signing.

Patch 7 adds comprehensive documentation and example XML files for
the conversion tool.
