Okay, not the 405, but the pre-existing yet until now secret A2O, which compared to the well-known in-order A2I added out-of-order execution at the cost of being reduced from SMT4 to SMT2.
Not too shabby for an embedded core.
And certainly more advanced than the 405 (or the 440 of the Sam460 ex), being 32bit Power ISA v.2.03 cores (roughly POWER5), where the A2O is 64bit Power ISA v.2.07 (roughly POWER8).
But apart from being ISA v.2.07 compatible it does not seem to feature a SIMD vector unit (Altivex, VSX) nor an MMU? (
