The structure is now broken into the top level structure which contains a field indicating the total size of the structure. Add a size parameter to the metadata access API functions to indicate the number of bytes to be accessed. This is then used to either read the entire structure, or only the top level structure.

fwu: meta-data: switch to management by common code 2023-06-09T17:52:40+00:00 Jassi Brar jaswinder.singh@linaro.org 2023-03-06T23:18:41+00:00 246ec2a12c437ff821e452104f3f564e5d25fa91 The common code can now read, verify and fix meta-data copies while exposing one consistent structure to users. Only the .read_mdata() and .write_mdata() callbacks of fwu_mdata_ops are needed. Get rid of .get_mdata() .update_mdata() .get_mdata_part_num() .read_mdata_partition() and .write_mdata_partition() and also the corresponding wrapper functions.
