Hello everyone,

I have been looking at SPDM attestation end-to-end testing using Renode and have a working bmcweb implementation of the Redfish ComponentIntegrity routes that consumes the D-Bus interfaces already merged in phosphor-dbus-interfaces [1]. I noticed that the previous bmcweb WIP for ComponentIntegrity was auto-abandoned [2] and there does not appear to be an active effort to implement these routes upstream.

The routes are designed to complement the spdmd D-Bus backend work currently in review [3][4], providing the Redfish frontend needed to complete the attestation stack described in the design document [5].

I wanted to check whether anyone is already working on bmcweb routes downstream before submitting to Gerrit. If not, I am happy to contribute and collaborate on getting this piece upstream.
