Hi Ard,
I have tested this applied on top of 4.15-rc7 running in a model.

For sha512-ce, I verified that tcrypt successfully passed tests for modes:
12, 104, 189, 190, 306, 406 and 424.
(and I double checked that sha512-ce was being used).

Similarly for sha384-ce, I tested the following modes:
11, 103, 187, 188, 305 and 405. 

Also, I had:
CONFIG_CRYPTO_MANAGER_DISABLE_TESTS=n

So FWIW, please feel free to add:
Tested-by: Steve Capper <steve.capper at arm.com>

Cheers,
