CC310 NRF Crypto Hash library incorrectly interprets output of hash_algorithm_get()

[nealjack]

In all instances where the internal function `hash_algorithm_get()` is used in `cc310_lib_hash.c`, the output is inverted, making would should be a successful return code return an error. SHA256 hashing seems to work fine if the two locations where this function is used is fixed.

Hey nealjack,

SDK15 is scheduled for release on monday. I need you to port to the new SDK when released and post your results. 

Cheers,

Håkon.

Hi Håkon,

I finally got around to updating to SDK15 and trying out the hash library. It now appears that the `CRYS_HASH_Finish` function causes a hard restart of my device. I'm running on top of softdevice s140 on the NRF52840. I attempted to copy a lot of the configuration from the nrf_crypto/hash example, and added a nrf_crypto_data section to my linker. It may be possible I didn't get it quite right.

I suggest you compare your linker to the one in the nrf_crypto/test_app example.
