The problem there is no end > user knows about this distinction. I think using internal code names like ARCH_QCOM_A_FAMILY here is fine, a lot of other platforms do similar things. Regarding end users, it's probably enough to explain the distinction in the help text, something like: The A-family includes all Snapdragon S1/S2/S3/S4 chips before 2013, up to the MSM8x60 and APQ8064 models. The B-family includes all Snapdragon 2xx/4xx/6xx/8xx models starting in 2013 with the MSM8x74. https://en.wikipedia.org/wiki/List_of_Qualcomm_Snapdragon_device has a good overview that translates the marketing names into the model numbers but it doesn't have internal code names, so I'm not sure where the APQ8064 fits it, as it was marketed as both the "S4 Pro" and the "600", depending on the revision.
