The Raspberry Pi Compute Module 4 IO Board is an application board for
the Compute Module 4. [1]

This patch adds support for the Radxa CM3J mounted on the RPi CM4 IO
Board.

Specification:
- 12V 5521 DC jack
- 2x full-size HDMI 2.0 connectors (only HDMI0 is supported with CM3J)
- Gigabit Ethernet RJ45 with PoE support
- 2x USB 2.0 connectors, with header for two more connectors
- Micro USB connector
- microSD card socket
- PCIe Gen 2 x1 socket
- 12V 4-pin PWM fan connector
- External power connector (+5V, +12V)
- 2x MIPI DSI connectors
- 2x MIPI CSI-2 connectors
- 40-pin GPIO header
- RTC with battery socket
- Red (power) and green (heartbeat) LEDs

During a cold boot, it does not work in U-Boot:

=> setenv ipaddr 192.168.0.99
=> ping 192.168.0.1
ethernet@fe010000 Waiting for PHY auto negotiation to complete....... done
Using ethernet@fe010000 device

ARP Retry count exceeded; starting again
ping failed; host 192.168.0.1 is not alive

However, it works fine in Linux, and also in U-Boot after a warm reboot.

It's labeled as '+1.8v' in the schematic. Do you have any other 
suggestions for the name?
