Run qemu-system-ppc without any arguments. There is a black bar
(because of vga.chain4), it shouldn't be there.
With your pci hole patch, it's fixed, except for:
escc_mem = escc_init(0x80013000, pic[0x25], pic[0x24],
serial_hds[0], serial_hds[1], ESCC_CLOCK, 4)
This puts escc bang into the framebuffer. Changing it to 0x90013000
makes the black bar go away.
Before the memory API, this worked, likely because the framebuffer
overlays escc.
The correct fix depends on what the hardware does. Is escc really
registered into the pci area, and again as a BAR?
If we reenable the collision warning in memory.c, we see
warning: subregion collision 80013000/40 (escc) vs 80000000/70000000
(pci-hole)
I'll work on reenabling ir permanently.
