Application of data descriptor maps in management of firmware control data

An electronic device, comprising:

• one or more processors;
• a memory device;
• and
• memory storing one or more programs for execution by the one or more processors, the one or more programs further comprising instructions for:
• obtaining a current data descriptor map (DDM) corresponding to a current version of a firmware program, wherein the current DDM maps a plurality of current data descriptors to a plurality of current locations in a current control data structure;
• identifying, in the memory device, a prior DDM and a prior control data structure corresponding to a prior version of the firmware program, wherein the prior DDM maps a plurality of prior data descriptors to a plurality of prior locations in the prior control data structure, and the prior control data structure stores a plurality of prior control data items identified by the plurality of prior data descriptors;
• automatically generating the current control data structure corresponding to the current version of the firmware program based on the prior control data structure, the current DDM, and the prior DDM, wherein the current control data structure stores a plurality of current control data items identified by the plurality of current data descriptors;
• and
• storing the current control data structure in the memory device.

A non-transitory computer-readable storage medium, storing one or more programs for execution by one or more processors, the one or more programs further comprising instructions for:

• obtaining a current data descriptor map (DDM) corresponding to a current version of a firmware program, wherein the current DDM maps a plurality of current data descriptors to a plurality of current locations in a current control data structure;
• identifying, in a memory device, a prior DDM and a prior control data structure corresponding to a prior version of the firmware program, wherein the prior DDM maps a plurality of prior data descriptors to a plurality of prior locations in the prior control data structure, and the prior control data structure stores a plurality of prior control data items identified by the plurality of prior data descriptors;
• automatically generating the current control data structure corresponding to the current version of the firmware program based on the prior control data structure, the current DDM, and the prior DDM, wherein the current control data structure stores a plurality of current control data items identified by the plurality of current data descriptors;
• and
• storing the current control data structure in the memory device.
