[PATCH 0/2] riscv: spacemit: add ethernet support for K3 SoC

[Yixun Lan]

This series try to add a Synopsys DWMAC glue driver for SpacemiT
K3 SoC, and also enable ethernet support in the defconfig file.

Tested on K3 Pico-ITX board with command of dhcp, ping, tftpboot.

[PATCH 1/2] net: dwc_eth_qos: spacemit: add support for K3 SoC

[Yixun Lan]

The SpacemiT K3 integrates a Synopsys DWMAC 5.40a Ethernet controller.
Add the platform glue for selecting the MII, RMII or RGMII interface,
configuring the internal RGMII delay lines through the APMU, and
managing the controller clocks and reset.

[PATCH 2/2] configs: spacemit: k3: Enable Ethernet support

[Yixun Lan]

Enable the SpacemiT platform glue for the DesignWare Ethernet QoS
controller together with the generic PHY framework, Gigabit Ethernet
PHY support and the Realtek PHY driver.

Enable DHCP, MII, ping and PXE commands for network configuration,
diagnostics and network boot. Allow U-Boot to generate a random
Ethernet address when no valid address is provided by the board.

Please also enable for this series: CMD_WGET DNS NET_LWIP

We can intentionally leave WGET_HTTPS behind when there is no
hardware-specific DM RNG driver implemented yet. I do not see a reason
for the legacy network stack instead of LwIP; LwIP appears to be working
well.

In my test I start a simple HTTP server on the local network host:

$ python3 -m http.server 8000
Serving HTTP on 0.0.0.0 port 8000 (http://0.0.0.0:8000/) ...

Next from a Sipeed K3 Pico-ITX 32GB board and your mainline u-boot series:

=> dhcp
ethernet@cac80000 Waiting for PHY auto negotiation to complete........ done
DHCP client bound to address <10.20.30.40> (38 ms)
=> wget http://host:8000/mini.efi
