Well, I tested that on an experimental hardware we were given by AMD.

cpuinfo says something like:
processor       : 6
BogoMIPS        : 500.00
Features        : fp asimd evtstrm aes pmull sha1 sha2 crc32 cpuid
CPU implementer : 0x41
CPU architecture: 8
CPU variant     : 0x1
CPU part        : 0xd07
CPU revision    : 2
