Merge branch 'octeontx2-pf-Add-network-driver-for-physical-function'

Sunil Goutham says:

====================
octeontx2-pf: Add network driver for physical function

OcteonTX2 SOC's resource virtualization unit (RVU) supports
multiple physical and virtual functions. Each of the PF's
functionality is determined by what kind of resources are attached
to it. If NPA and NIX blocks are attached to a PF it can function
as a highly capable network device.

This patch series add a network driver for the PF. Initial set of
patches adds mailbox communication with admin function (RVU AF)
and configuration of queues. Followed by Rx and tx pkts NAPI
handler and then support for HW offloads like RSS, TSO, Rxhash etc.
Ethtool support to extract stats, config RSS, queue sizes, queue
count is also added.

Added documentation to give a high level overview of HW and
different drivers which will be upstreamed and how they interact.

Changes from v5:
* Fixed otx2_atomic64_add() non ARM64 fallback definition.
- Suggested by David Miller

Changes from v4:
* Replaced pci_set_dma_mask and pci_set_consistent_dma_mask
fn()s with dma_set_mask_and_coherent().
* Some additonal code cleanup.
* Fixed receive buffer segmnetation logic in otx2_alloc_rbuf()
* Removed all unused BIG_ENDIAN structure definitions.
* Removed unnecessary memory barriers
- Sugested by Jakub Kicinski
* Fixed mailbox initalization failure handling
* Removed unused function parameter in otx2_skb_add_frag()
- Suggested by Maciej Fijalkowski

Changes from v3:
* Fixed receive side scaling reinitialization during interface
DOWN and UP to retain user configured settings, if any.
* Removed driver version from ethtool.
* Fixed otx2_set_rss_hash_opts() to return error incase RSS is
not enabled.
- Sugested by Jakub Kicinski

Changes from v2:
* Removed frames, bytes, dropped packet stats from ethtool to avoid
duplication of same stats in netlink and ethtool.
- Sugested by Jakub Kicinski
* Removed number of channels and ringparam upper bound checking
in ethtool support.
* Fixed RSS hash option setting to reject unsupported config.
- Suggested by Michal Kubecek

Changes from v1:
* Made driver dependent on 64bit, to fix build errors related to
non availability of writeq/readq APIs for 32bit platforms.
- Reported by kbuild test robot

Merge branch 'octeontx2-af-Add-RVU-Admin-Function-driver'

octeontx2-af: Add RVU Admin Function driver

Resource virtualization unit (RVU) on Marvell's Octeo

Merge branch 'octeontx2-af-Add-RVU-Admin-Function-driver'

Sunil Goutham says:

====================
octeontx2-af: Add RVU Admin Function driver

Resource virtualization unit (RVU) on Marvell's OcteonTX2 SOC maps HW
resources from the network, crypto and other functional blocks into
PCI-compatible physical and virtual functions. Each functional block
again has multiple local functions (LFs) for provisioning to PCI devices.
RVU supports multiple PCIe SRIOV physical functions (PFs) and virtual
functions (VFs). PF0 is called the administrative / admin function (AF)
and has privileges to provision RVU functional block's LFs to each of the
PF/VF.

RVU managed networking functional blocks
- Network pool allocator (NPA)
- Network interface controller (NIX)
- Network parser CAM (NPC)
- Schedule/Synchronize/Order unit (SSO)

RVU managed non-networking functional blocks
- Crypto accelerator (CPT)
- Scheduled timers unit (TIM)
- Schedule/Synchronize/Order unit (SSO)
Used for both networking and non networking usecases
- Compression (upcoming in future variants of the silicons)

Resource provisioning examples
- A PF/VF with NIX-LF & NPA-LF resources works as a pure network device
- A PF/VF with CPT-LF resource works as a pure cyrpto offload device.

This admin function driver neither receives any data nor processes it i.e
no I/O, a configuration only driver.

PF/VFs communicates with AF via a shared memory region (mailbox). Upon
receiving requests from PF/VF, AF does resource provisioning and other
HW configuration. AF is always attached to host, but PF/VFs may be used
by host kernel itself, or attached to VMs or to userspace applications
like DPDK etc. So AF has to handle provisioning/configuration requests
sent by any device from any domain.

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 (MAC controller) driver which communicates with firmware for
managing physical ethernet interfaces. AF collects info from this
driver and forwards the same to the PF/VFs uaing these interfaces.

This is the first set of patches out of 80+ patches.

Changes from v8:
1 Removed unnecessary typecasts in entire series
- Suggested by David Miller
2 Added COMPILE_TEST to AF driver
- Suggested by Arnd Bergmann
3 Changed udelay() to usleep_range() in rvu_poll_reg
- Suggested by Arnd Bergmann
4 MSIX vector base IOMMU mapping is done using dma_map_resource()
API instead of dma_map_single() as it accepts physical address.
- Issue pointed by Arnd Bergmann

Changes from v7:
1 Removed unnecessary typecasts in mbox infra code.
- Suggested by David Miller
2 Fixed MAINTAINERS patch
- Suggested by Joe Perches

Changes from v6:
Fixed ordering of local variables from longest to shortest line.
- Suggested by David Miller

Changes from v5:
Modified bitfield based command structures to bitmasks for communication
with firmware, to address endianness issues.
- Suggested by Arnd Bergmann

Changes from v4:
1 Removed module author/version/description from CGX driver as it's now
merged with AF driver module.
- Suggested by Arnd Bergmann
2 Added big-endian bitfields for CGX's kernel <=> firmware communication
command structures.
- Suggested by Arnd Bergmann

Changes from v3:
Moved driver from drivers/soc to drivers/net/ethernet
- Suggested by Arnd Bergmann
https://patchwork.kernel.org/cover/10587635/

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
