Right. I thought to do so is easy, but that turned out to reveal a lot of other issues: - hppa is using the I8259 code, which relies on ISA - hw/hppa/pci.c seems to only contain unused stuff - LASI use hw/char/parallel.c, which relies on ISA. parallel.c could propably be split up into a ISA dependent part and a generic part So it is more work to remove ISA completely, therefore i'll drop that patch for now and submit it later again.
