[0/9] Add Support for Marvell OcteonTX2 CPT engine

Message

Srujana Challa Jan. 6, 2021, 10:42 a.m. UTC

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 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:
- 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.
