In the FWU Multi Bank Update feature, the information about the updatable images is stored as part of the metadata, which is stored on a dedicated partition. Add the metadata structure, and functions to access the metadata. These are generic API's, and implementations can be added based on parameters like how the metadata partition is accessed and what type of storage device houses the metadata.

What is this, please? Could you add a link to the docs in the commit message and something in doc/ as well?
This is implementation of the FWU[1] specification from Arm. Some aspects of the DependableBoot[2] specification are also implemented. I had put pointers to the document in the cover letter[3]. I have not added any documentation yet, since this is a rfc. Will do so once the initial reviews are completed. Hope that is fine.
