Subject: [PATCH v10,net-next,0/3] Add Support for Marvell OcteonTX2 Cryptographic

This patchset adds support for CPT in OcteonTX2 admin function(AF).
CPT is a cryptographic accelerator unit and it includes microcoded
Giga Cipher engines.

OcteonTX2 SOC's resource virtualization unit (RVU) supports multiple
physical and virtual functions. Each of the PF/VF's functionality is
determined by what kind of resources are attached to it. When the CPT
block is attached to a VF, it can function as a security device.
The following document provides an overview of the hardware and
different drivers for the OcteonTX2 SOC:
https://www.kernel.org/doc/Documentation/networking/device_drivers/marvell/octeontx2.rst

This patch series includes:
- Patch to update existing Marvell sources to support CPT.
- Patch that adds mailbox messages to the admin function (AF) driver,
to configure CPT HW registers.
- Patch to provide debug information about CPT.

Changes since v9:
 * Dropped CPT PF & VF driver patches to submit to cryptodev-2.6 in next
   release cycle.
Changes since v8:
 * Load firmware files individually instead of tar.
Changes since v7:
 * Removed writable entries in debugfs.
 * Dropped IPsec support.
Changes since v6:
 * Removed driver version.
Changes since v4:
 * Rebased the patches onto net-next tree with base
   'commit bc081a693a56 ("Merge branch 'Offload-tc-vlan-mangle-to-mscc_ocelot-switch'")'
Changes since v3:
 * Splitup the patches into smaller patches with more informartion.
Changes since v2:
 * Fixed C=1 warnings.
 * Added code to exit CPT VF driver gracefully.
 * Moved OcteonTx2 asm code to a header file under include/linux/soc/
Changes since v1:
 * Moved Makefile changes from patch4 to patch2 and patch3.

Srujana Challa (3):
  octeontx2-pf: move lmt flush to include/linux/soc
  octeontx2-af: add mailbox interface for CPT
  octeontx2-af: add debugfs entries for CPT block
