RockPro64, part two

[John Klos <john%ziaspace.com@localhost>]

I've got my RockPro64 up and running thanks to Jared McNeill's fixes. 
While a kernel built shortly after November 13th would crash quickly after 
booting, usually while starting sshd, and entering the debugger didn't 
work then, a kernel from today's sources works well, debugger and all.

A few notes:

The image from Jared's page (http://www.invisible.ca/arm/) for the 
RockPro64 doesn't work as-is. It tries to boot "netbsd" from, I presume, 
the MS-DOS partition, but the MS-DOS partition only has a netbsd.img file 
for Raspberry Pis.

Updating using rksd_loader.img from today's pkgsrc had different behavior, 
which is that it loads /netbsd from the FFS partition, which works fine. 
On the other hand, there's no two second count-down to interrupt the boot 
process.

USB doesn't seem to work correctly. When an SSD drive is connected to a 
USB 3 port, nothing happens, even when the drive is connected pre-boot. 
When the same drive is connected to a USB 2 port, sometimes the drive is 
recognized for the full 112 gigs, and sometimes it isn't. I haven't 
figured out any pattern yet:

umass0 at uhub3 port 1 configuration 1 interface 0

[ 656.5053238] sd0(umass0:0:0:0): illegal request, data = 00 00 00 00 20 00 00 00 00 00

PCIe isn't recognized, neither with nor without something in the PCIe slot 
(I tried with an NVMe and nvme* at pci?).

The built-in gigabit ethernet isn't working. It gets link, and it says it 
gets link, but nothing appears on the wire. The link LED on the port 
doesn't work, but the orange LED does blink when I try to create traffic 
from the other end.

I'll keep testing things.

Thanks!
John
