This series adds PLDM-based firmware update support to the pds_core driver. PLDM (Platform Level Data Model) is a DMTF standard for firmware management that provides a vendor-neutral interface for firmware updates.
The implementation uses the kernel's pldmfw library for package parsing and component matching. Users can update entire firmware packages or individual components via devlink flash. Component information is displayed via devlink info, showing firmware versions and update status for each component. The series also adds host backed memory support, allowing firmware to request memory pages from the host for its operations. Signed-off-by: Nikhil P.
