From 04711d41a87240b6a872bbfa5dd54a9daaa1bc27 Mon Sep 17 00:00:00 2001 From: Akhil Goyal Date: Thu, 20 Apr 2017 11:14:19 +0530 Subject: [PATCH] crypto/dpaa2_sec: add run-time assembler for descriptor A set of header files(hw) which helps in making the descriptors that are understood by NXP's SEC hardware. This patch provides header files for command words which can be used for descriptor formation.
