rpi4 headless experience

[Dan Mack]

Just tried the latest FreeBSD on RPI image on my rpi4-4GB system.  Here's 
what I experienced in case anyone else is interested:

- Install method - I just dd'd the unxz'd image from the download site
   onto a new microSD card.

- used a serial port connected RPI to another RPI using a ttl to usb 
cable.

- powered on, freebsd booted up just fine.

I pluged in a USB connected SSD and it was not recognized on either USB2 
or USB3 ports.

And the memory size is not reporting the full 4GB as can be seen above.

Ethernet is working without any changes (dhcp kicked in by default) and 
seems to work.

Not sure about the on-board WiFI.

That's it, if anyone knows the status of the USB support or how to get the 
system to see all the memory, let me know :-)
