SPARC T4 or later.
The T2 and T3 has a separate crypto unit, but not supported here.
Support was removed from the kernel in 6.14. Haven't tested it, as I
don't have the hardware.
Also worth noting, it's only used when the firmware lists the machine
description's hwcap-list and the CFR has its bit set.
I have no idea about Fujitsu's SPARC64 X family.
