A small series of patches which enhances the graphics output on 64-bit hppa
machines. Allows to disable the artist graphic card and introduces drivers for
the Diva GSP (remote management) cards which are used in later 64-bit machines
and which we now use for serial console output.

The LMMIO regions of the Astro chip are now supported too, which e.g. allows to
plug in a virtual ATI PCI card with a 64-bit Linux kernel.

Please review.

Helge Deller (6):
  hw/char: Add emulation of Diva GSP PCI management boards
  hw/hppa: Wire up Diva GSP card
  artist: Allow disabling artist on command line
  hw/hppa: Avoid creation of artist if disabled on command line
  hw/pci-host/astro: Add LMMIO range support
  target/hppa: Update SeaBIOS-hppa
