[OpenWrt-Devel] [PATCH 2/2] kernel: package module for SafeXcel crypto engine

[Tomasz Maciej Nowak]

Supports EIP97 and EIP197 found on Armada 37xx, 7k and 8k SoCs.
Unfortunately firmware for EIP197 is not easily obtainable, therefore
to not cause lot of user requests directed at OpenWrt, package it as
module with explanation where to obtain the firmware.
