Recognize the qemu --nodefaults option, which will disable the
following default devices on hppa:
- lsi53c895a SCSI controller,
- artist graphics card,
- LASI 82596 NIC,
- tulip PCI NIC,
- second serial PCI card,
- USB OHCI controller.
Adding this option is very useful to allow manual testing and
debugging of the other possible devices on the command line.

With this patch in the tree, I get some interesting crashes in Seabios
if I provide a somewhat unusual command line option. For example,
something like
-usb -device usb-ehci,id=ehci \
-device usb-uas,bus=ehci.0,id=uas \
-device scsi-hd,bus=uas.0,scsi-id=0,lun=0,drive=d0 \
-drive file= ...
is accepted as command line option but results in

SeaBIOS wants SYSTEM HALT.
This is without --nodefaults, and it used to work. Is that intentional ?
If I do use the --nodefaults parameter, I was unable to figure out how
to configure the serial console. What command line parameter(s) do I need to
get it ?

Just in case it matters, the following partial revert fixes the problem
for me.

It seems that SeaBIOS doesn't like it if the SCSI interface is missing.

This should now be fixed in the upcoming SeaBIOS-hppa-v16 version ("devel" branch):
https://github.com/hdeller/seabios-hppa/tree/devel
Could you test?
If it doesn't work, please give me the full command line.

You need to add:
-serial mon:stdio
This will create a serial port if it's not yet there.
Thanks for your testing!

I was able to build from the 'master' branch, but 'devel' gives me
hppa64-linux-ld: target elf32-hppa-linux not found
Do you have a binary seabios image, by any chance ?

This is with qemu 8.2.1. Note that the number of CPUs doesn't make a
difference. It turns out this also crashes/aborts immediately with
"nodefaults".

And there was me trying all variants of "-device pci-serial-4x..." I could
think of ;-).

The devel branch now includes a 64-bit firmware too.
You need both, hppa (32-bit) and hppa64 (64-bit) gcc
and binutils packages installed.

That line boots for me now.

Adding "--nodefaults -serial mon:stdio" to the line above works too.
