Well I'm out of time, given another month I might have made it work.  Here is
my final commit:

https://github.com/pbug44/openbsd-src/commit/e25ff39b81043bbfb71c588fec7eb6c3c0025d91

Another failure, but I learned a lot so it was a success in my eyes.  I'm going
back to programming on my delphinusdnsd for the rest of this year.  That's my
priority.

I'm passing the torch to Miguel, Moritz and Mark who I've been having steady
contact with throughout this.  They have this hardware and are able to
make it work given time.  If nothing happens by december, I may be able to
pick up on this (if I want).

Just a status report, I got it to boot to the exec'ing init.  I had to
disable plic0 and com0, and am running on the boot loaders console.  That is
probably why I see no installer message (no /dev/console).

So that is the work that still needs to be done, getting the console working
right.  It's the same as the Allwinner H6 (APB driven), though when I enable
cn_tab (which I hashed out) in /sys/dev/fdt/com_fdt.c then all I see is 
one or two bytes in the serial cu, and it reminds me of a speedrate problem.
I haven't figured that out yet.

The other thing is the plic.  I did workarounds to get around its freezing,
but those are likely wrong.  Because when an IRQ gets enabled it freezes the
boot process.  I'll hopefully get this all fixed up by next weekend at which
time I'm going back to dns programming (shift of priorities).

Here is the dmesg to the point of WARNING: CHECK AND RESET THE DATE!

RISCV - port to Mango Pi MQ-Pro (D1)

2023-09-18 Thread Peter J. Philipp 
Hi,

I've been working a little bit on making OpenBSD run on Mango Pi, I haven't
succeeded yet, but I think we're close.  My patches are here:

https://github.com/pbug44/openbsd-src/tree/MANGOPI

it's a forked version of OpenBSD src with a "MANGOPI" branch.  I used to
send patches around to several OpenBSD devs but now it's probably better
to have a repo for it.

If you have this hardware and want OpenBSD running on it, help us!  If you
don't know how to program perhaps you can build-test.  I haven't merged
this patch yet, but I'll be working on this (it was compiling on a sept. 1st
version of -current).

A Mango Pi was sent to OpenBSD but came back to me after some time waiting
to be picked up at a postal outlet.  I don't know why they didn't call the
OpenBSD dev, the number was on the address.  Or perhaps they did and he
was on vacation at the time.  I still want to give this to the OpenBSD dev
that I sent it to, unless he doesn't want it, I still want to give this to
OpenBSD.  OpenBSD, contact me with new postal address information.

Best Regards,
-peter
