Hello Elad,

> Add support for Armada 7020 Express Type 7 CPU module board by Marvell.
> Add device tree bindings for this board.
> Define this COM Express CPU module as dtsi and provide a dtsi file for
> the carrier board (Marvell DB-98CX85x0 COM Express type 7 carrier board).
>
> Since memory is soldered on CPU module, memory node is on CPU module
> dtsi file.
>
> This Carrier board only utilizes the PCIe link, hence no special device
> or driver support is provided by this dtsi file.
> Devise a dts file for the combined com express carrier and CPU module.

> The Aramda 7020 CPU COM Express board offers the following features:
>
> 1. Armada 7020 CPU, with dual ARM A72 cores
> 2. DDR4 memory, 8GB, on board soldered
> 3. 1Gbit Out of Band Ethernet via RGMII to PHY and RJ45 connector,
> all are present on A7K CPU module (none on the carrier)
> 4. Optional 10G KR Ethernet going via the COM Express type 7 connector
> 5. On-board 8 Gbit, 8-bit bus width NAND flash
> 6. On-board 512 Mbit SPI flash
> 7. PCIe Root Complex, 4 lanes PCIe gen3 connectivity, going via the
> COM Express type 7 connector
> 8. m.2 SATA connector
> 9. Micro-SD card connector
> 10. USB 2.0 via COM Express type 7 connector
> 11. Two i2c interfaces - one to the CPU module, and one to the
> carrier board via the COM Express type 7 connector
> 12. UART (mini USB connector by virtue of FT2232D UART to USB
> converter, connected to the Armada 7020 UART0)
>
> v2:
> 1) update 10gbase-kr to 10gbase-r in dtsi

I’ve already merged your previous version with this fix and even
included it in the PR for the next release.
However, I noticed a comment from Andrew. Could you provide a fix for
it, and I’ll try to include it i
Thanks,
Gregory
