This series introduces crypto(CPT) drivers(PF & VF) for Marvell OcteonTX2
CN96XX Soc.

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

The CPT PF driver is responsible for:
- Forwarding messages to/from VFs from/to admin function(AF),
- Enabling/disabling VFs,
- Loading/unloading microcode (creation/deletion of engine groups).

The CPT VF driver works as a crypto offload device.

This patch series includes:
- Patch to update existing Marvell sources to support the CPT driver.
- Patch that adds mailbox messages to the admin function (AF) driver,
to configure CPT HW registers.
- CPT PF driver patches that include AF<=>PF<=>VF mailbox communication,
sriov_configure, and firmware load to the acceleration engines.
- CPT VF driver patches that include VF<=>PF mailbox communication and
crypto offload support through the kernel cryptographic API.

This series is tested with CRYPTO_EXTRA_TESTS enabled and
CRYPTO_DISABLE_TESTS disabled.

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 (13):
  octeontx2-pf: move lmt flush to include/linux/soc
  octeontx2-af: add mailbox interface for CPT
