[PATCH v2 0/3] arm64: dts: marvell: Add Sophos XGS 107w NPU

[Nicolo Giuliani via B4 Relay]

The Sophos XGS 87/107 desktop firewalls pair an AMD x86 host with a
separate network processing unit (NPU): a Marvell Armada CN9130 SoC with
its own eMMC and SPI NOR flash. The NPU serves the eight RJ45 ports and
the SFP cage through a Marvell 88E6193X switch on its MDIO bus, which is
connected to the SoC by a 10GBASE-R link, and reaches the x86 host over
PCIe.

This series adds the Sophos vendor prefix, the compatible string of the
NPU board and a device tree that describes the NPU as a standalone system:
UART console, eMMC, SPI NOR flash, the SFP cage and the switch with its
ports. The port LEDs, the USB ports and the PCIe link to the x86 host (the
CN9130 acts as a PCIe endpoint towards it, which needs endpoint support
that is not part of this series) are not described.

Tested on an XGS 107w with Linux 6.18: boot from eMMC, eMMC and SPI NOR
access, the mvpp2 link to the switch at 10 Gb/s, the 88E6193X probing with
its eight user ports, and 936 Mbit/s through a front port. The SFP cage
is untested.

dt_binding_check passes for vendor-prefixes.yaml and armada-7k-8k.yaml,
and CHECK_DTBS=y on marvell/cn9130-sophos-xgs107w.dtb reports no warning
specific to this board.

Based on the mvebu/dt branch of the mvebu tree (008e9faade).

[Nicolo Giuliani via B4 Relay]

From: Nicolo Giuliani <nicolo.giuliani6@studio.unibo.it>

The Sophos XGS 87/107 desktop firewalls combine an AMD x86 host with a

SoC with its own eMMC and SPI NOR flash, connected to the x86 host over

Document the compatible string of the NPU board, with the CN9130 SoC
compatibles as fallbacks.

I don't know which fallbacks are right, why cn9130 sometimes has,
sometimes does not, I guess Marvell maintainers will sort it out:

[PATCH v2 3/3] arm64: dts: marvell: Add Sophos XGS 107w NPU board

[Nicolo Giuliani via B4 Relay]

From: Nicolo Giuliani <nicolo.giuliani6@studio.unibo.it>

Add a device tree for the network processing unit (NPU) of the Sophos
XGS 87/107 desktop firewalls. The appliance pairs an AMD x86 host with the
NPU, a Marvell Armada CN9130 SoC with its own eMMC and SPI NOR flash that
runs independently of the host and serves the front panel ports.

The eight RJ45 ports and the SFP cage are connected through a Marvell
88E6193X switch on the MDIO bus of the SoC, at address 2. Switch port 0
is the CPU port, a 10GBASE-R link to the first mvpp2 port. Ports 1 to 8
are the RJ45 ports, which use the internal PHYs of the switch, and
port 9 is the SFP cage, connected over 1000BASE-X.

Describe the UART console, the eMMC, the SPI NOR flash that holds the boot
loader and its environment (read-only), the SFP cage and the switch with
its ports. The port LEDs, the PCIe link to the x86 host and the USB ports
are not described.

The switch is reset through CP GPIO2 pin 17.

Tested on an XGS 107w with Linux 6.18: boot from eMMC, eMMC and SPI NOR
access, the mvpp2 link to the switch at 10 Gb/s, the 88E6193X probing with
its eight user ports, and 936 Mbit/s through a front port. The SFP cage is
untested.

The Sophos XGS 87/107 desktop firewalls pair an AMD x86 host with a
separate network processing unit (NPU): a Marvell Armada CN9130 SoC with
its own eMMC and SPI NOR flash. The NPU serves the eight RJ45 ports and
the SFP cage through a Marvell 88E6193X switch on its MDIO bus, which is
connected to the SoC by a 10GBASE-R link, and reaches the x86 host over

This series adds the Sophos vendor prefix, the compatible string of the
NPU board and a device tree that describes the NPU as a standalone system:
UART console, eMMC, SPI NOR flash, the SFP cage and the switch with its
ports. The port LEDs, the USB ports and the PCIe link to the x86 host (the
CN9130 acts as a PCIe endpoint towards it, which needs endpoint support

Tested on an XGS 107w with Linux 6.18: boot from eMMC, eMMC and SPI NOR

its eight user ports, and 936 Mbit/s through a front port. The SFP cage
