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.
