* remotes/vivier/tags/q800-branch-pull-request:
  BootLinuxConsoleTest: Test the Quadra 800
  hw/m68k: define Macintosh Quadra 800
  hw/m68k: add a dummy SWIM floppy controller
  hw/m68k: add Nubus macfb video card
  hw/m68k: add Nubus support
  hw/m68k: implement ADB bus support for via
  hw/m68k: add VIA support
  dp8393x: manage big endian bus
  esp: add pseudo-DMA as used by Macintosh
  esp: move get_cmd() post-DMA code to get_cmd_cb()
  esp: move handle_ti_cmd() cleanup code to esp_do_dma().
