MVEBU's EIP97 and EIP197 Cryptographic Engine driver designed by
Inside Secure. This is found on Marvell Armada 37xx/7k/8k SoCs.

Particular version of these IP (EIP197B and EIP197D) require firmware.
The mini firmware package provides limited functionality, for most operations
a full-featured firmware is required. Unfortunately the "full" firmware is not
freely available and needs signed Non-Disclosure Agreement (NDA) with Marvell.
For those who have signed NDA the firmware can be obtained at
https://extranet.marvell.com.
