Agree, this was done by watching the Power 8 patchset. But this seems quite logical. > > Besides, do we really need this -a suffix ? It is the full name of the ARM architecture - armv7, A profile. There are 3 profiles: A - application, R - real time, M - microcontroller. They differ in what MMU/MPU and other such things they support. But, finally, we can omit. The M profile is unsuitable for DPDK anyway. The R profile may be however used under certain circumstances (I believe, it can run Linux).
