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.

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over

decreasing, but there are still more than 2400 instances.

This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.

There are a variety of indentation styles found.

a) 4 spaces + '---help---'
b) 7 spaces + '---help---'

d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)

Remove dependencies on HAS_DMA where a Kconfig symbol depends on another
symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST".
In most cases this other symbol is an architecture or platform specific
symbol, or PCI.

Generic symbols and drivers without platform dependencies keep their
dependencies on HAS_DMA, to prevent compiling subsystems or drivers that
cannot work anyway.

This simplifies the dependencies, and allows to improve compile-testing.

net: mvpp2: phylink support

Convert the PPv2 driver to implement phylink helpers, and use phylink in
DT mode. The other mode supported is ACPI, which will need further work
in order to be entirely compatible with phylink.

The MAC and GoP configuration functions were completely moved to fit
into the phylink helpers. When a PHY is always present between the MAC
and the physical port, phylink only is used, but when this is not the
case (the MAC directly is connected to the physical port) the link IRQ
is used to detect changes in the link state and call phylink_mac_change.

The ACPI mode do not uses phylink as of now, and the changes shouldn't
impact its use.

The mvpp2 is going to be extended to support the Marvell Armada 7K/8K
platform, which is ARM64. As a preparation to this work, this commit
enables building the mvpp2 driver on ARM64, by:

- Adjusting the Kconfig dependency

- Fixing the types used in the driver so that they are 32/64-bits
compliant. We use dma_addr_t for DMA addresses, and unsigned long
for virtual addresses.

It is worth mentioning that after this commit, the driver is for now
still only used on 32-bits platforms, and will only work on 32-bits
platforms.

net: mvneta: Add network support for Armada 3700 SoC

Armada 3700 is a new ARMv8 SoC from Marvell using same network controller
as older Armada 370/38x/XP. There are however some differences that
needed taking into account when adding support for it:

* open default MBUS window to 4GB of DRAM - Armada 3700 SoC's Mbus
configuration for network controller has to be done on two levels:
global and per-port. The first one is inherited from the
bootloader. The latter can be opened in a default way, leaving
arbitration to the bus controller. Hence filled mbus_dram_target_info
structure is not needed

* make per-CPU operation optional - Recent patches adding RSS and XPS
support for Armada 38x/XP enabled per-CPU operation of the controller
by default. Contrary to older SoC's Armada 3700 SoC's network
controller is not capable of per-CPU processing due to interrupt lines'
connectivity. This patch restores non-per-CPU operation, which is now
optional and depends on neta_armada3700 flag value in mvneta_port
structure. In order not to complicate the code, separate interrupt
subroutine is implemented.

For now, on the Armada 3700, RSS is disabled as the current
implementation depend on the per cpu interrupts.

marvell: mark mvneta and mvpp2 32-bit only

Both of these drivers won't work on 64-bit architectures unless they

This limits the COMPILE_TEST option for the two drivers again to
only build them on 32-bit. This seems nicer than shutting up the
warnings, in case we ever actually want to use them on 64-bit,
as the warnings indicate which parts of the driver are currently
broken there.
