[Qemu-devel] Sparc32 scsi (esp) and openboot

trying to make the proprietary OBP to boot, I got to the point where
SBus probe finds the scsi controller.
The next step is to find the devices attached to it, but here I get ESP errors.

Actually, I wonder if the very first ESP error may bring ESP in the
state, where it doesn't work properly anymore. The error happens
pretty early, before the "Power-ON Reset" message from OBP.

$ qemu-system-sparc -M SS-20 -L ~/sparc/ -bios ss20_v2.25_rom -nographic  -m 512
