Mark Cave-Ayland recently asked me about the ESP patches for the
next-cube machine that I once posted a long time ago, but never
got it merged (since Mark is currently working on improving the
ESP device). With his help, I dusted off the ESP patch, but we
had to discover that the firmware also wants to see the NIC
device in the MMIO region, otherwise it often crashes or hangs.
So here's now the current set of patches for the next-cube machine.
Both, the ESP SCSI controller and the NIC do not properly work
yet, but at least the next-cube firmware gets much further now
during it selftest, so I think this is a good base for future
work and experiments.
Thomas Huth (5):
hw/m68k/next-cube: Mirror BIOS to address 0
hw/scsi/esp: Work around problem with PIO data read for the NeXT-Cube
machine
m68k: Instantiate the ESP SCSI controller for the NeXTcube machine
hw/m68k/next-cube: Remove unused NEXTDMA_EN code
m68k: Add NeXTcube network controller
