Don't think there is anything within the DWC3 core that would be different specifically for 2.00a versus previous revisions. (so far)
Why add a define that is not used?
There is a running list of all the DWC3 revisions. Not all of them are being used, so my understanding was that we're just keeping track of all possible version values that can be read from the DWC3 version HW register. If this is the not the case, maybe we can just leave this out until we find a need to add it.
Thanks Wesley Cheng
