Cheers, I've queued this up as a fix.

I also updated the E1009 entry in silicon-errata.rst but, in doing so, I
noticed that E1041 is listed there which apparently also affects
Kry^H^H^HHydra [1].

At which point, maybe we should rename both Kryo and Falkor in the tree
so that we consistently refer to Hydra as the underlying micro-architecture.
Obviously not something for 5.4, but it would sure help me to understand
what's doing on here.

Thoughts?
