[PATCH 0/1] aspeed: msx4: enable BMC networking via MAC0

[Ender Hsieh]

Add the &mac0/&mdio3/ethphy3 nodes to the NVIDIA MSX4 board dts to
enable BMC networking. These nodes were intentionally omitted in
commit f28674fab34f ("ARM: dts: aspeed: Add NVIDIA MSX4 HPM") at
Andrew Lunn's request, pending RGMII delay handling clarification.

Following his guidance on linux-aspeed [1], the U-Boot bootloader
has been modified to stop enabling MAC clock delays on the SoC
side. With phy-mode = "rgmii-id", the PHY now adds the required
~2ns delay without any double-delay from the MAC controller.

Tested on alon8 hardware: 1G link negotiation succeeds with this
change in coordination with the U-Boot patch [2].
