73ef239cd8 net: marvell: prestera: implement br_port_locked flag offloading
Both <port> br_port_locked and <lag> interfaces's flag
offloading is supported. No new ABI is being added,
rather existing (port_param_set) API call gets extended.

fec7c9c73f net: marvell: prestera: define MDB/flood domain entries and HW API to offload them to the HW
Define MDB entry that can be offloaded:
  - FDB entry, that defines an multicast group to which traffic can be
    replicated to;
Define flood domain:
  - Arrangement of ports (list), that have joined multicast group, which
    would receive and replicate to multicast traffic of specified group;
Define flood domain port:
  - single flood domain list entry, that is associated with any given
    bridge port interface (could be LAG interface or physical port-member).
    Applicable to both Q and D bridges;

bb5dbf2cc6 net: marvell: prestera: add firmware v4.0 support
Add firmware (FW) version 4.0 support for Marvell Prestera
driver.

Major changes have been made to new v4.0 FW ABI to add support
of new features, introduce the stability of the FW ABI and ensure
better forward compatibility for the future driver vesrions.

Current v4.0 FW feature set support does not expect any changes
to ABI, as it was defined and tested through long period of time.
The ABI may be extended in case of new features, but it will not
break the backward compatibility.

ABI major changes done in v4.0:
- L1 ABI, where MAC and PHY API configuration are split.
- ACL has been split to low-level TCAM and Counters ABI
  to provide more HW ACL capabilities for future driver
  versions.

To support backward support, the addition compatibility layer is
required in the driver which will have two different codebase under
"if FW-VER elif FW-VER else" conditions that will be removed
in the future anyway, So, the idea was to break backward support
and focus on more stable FW instead of supporting old version
with very minimal and limited set of features/capabilities.

Improve FW msg validation:
 * Use __le64, __le32, __le16 types in msg to/from FW to
   catch endian mismatch by sparse.
 * Use BUILD_BUG_ON for structures sent/recv to/from FW.

501ef3066c net: marvell: prestera: Add driver for Prestera family ASIC devices
Marvell Prestera 98DX326x integrates up to 24 ports of 1GbE with 8
ports of 10GbE uplinks or 2 ports of 40Gbps stacking for a largely
wireless SMB deployment.

The current implementation supports only boards designed for the Marvell
Switchdev solution and requires special firmware.

The core Prestera switching logic is implemented in prestera_main.c,
there is an intermediate hw layer between core logic and firmware. It is
implemented in prestera_hw.c, the purpose of it is to encapsulate hw
related logic, in future there is a plan to support more devices with
different HW related configurations.

This patch contains only basic switch initialization and RX/TX support
over SDMA mechanism.

Currently supported devices have DMA access range <= 32bit and require
ZONE_DMA to be enabled, for such cases SDMA driver checks if the skb
allocated in proper range supported by the Prestera device.

Also meanwhile there is no TX interrupt support in current firmware
version so recycling work is scheduled on each xmit.

Port's mac address is generated from the switch base mac which may be
provided via device-tree (static one or as nvme cell), or randomly
generated. This is required by the firmware.
