[PATCH v3 00/15] soc: octeontx2: Add RVU admin function driver

[sunil . kovvuri]

From: Sunil Goutham <sgoutham@xxxxxxxxxxx>

Resource virtualization unit (RVU) on Marvell's OcteonTX2 SOC supports
multiple PCIe SRIOV physical functions (PFs) and virtual functions (VFs).
PF0 is called administrative / admin function (AF) and has privilege access
to registers to provision different RVU functional blocks to each of
PF/VF.

This admin function (AF) driver acts as a configuration / administrative
software which provisions functional blocks to a PF/VF on demand for them
to work as one of the following
 - A basic network controller (i.e NIC).
 - NIC with packet filtering, shaping and scheduling capabilities.
 - A crypto device.
 - A combination of above etc.

PF/VFs communicate with admin function via a shared memory region.
This patch series adds logic for the following
 - RVU AF driver with functional blocks provisioning support
 - Mailbox infrastructure for communication between AF and PFs.
 - CGX driver which provides information about physcial network
   interfaces which AF processes and forwards required info to
   PF/VF drivers.

This is the first set of patches out of 70 odd patches.

Note: This driver neither receives any data nor processes it i.e no I/O,
      just does the hardware configuration.

Changes from v2:
 No changes, submitted again with netdev mailing list in loop.
   - Suggested by Arnd Bergmann and Andrew Lunn

Changes from v1:
 1 Merged RVU admin function and CGX drivers into a single module
   - Suggested by Arnd Bergmann
 2 Pulled mbox communication APIs into a separate module to remove
   admin function driver dependency in a VM where AF is not attached.
   - Suggested by Arnd Bergmann
