* remotes/rth/tags/pull-pa-20200127:
  target/hppa: Allow, but diagnose, LDCW aligned only mod 4
  hw/hppa/machine: Map the PDC memory region with higher priority
  hw/hppa/machine: Restrict the total memory size to 3GB
  hw/hppa/machine: Correctly check the firmware is in PDC range
  hppa: Add emulation of Artist graphics
  seabios-hppa: update to latest version
  hppa: Switch to tulip NIC by default
  hppa: add emulation of LASI PS2 controllers
  ps2: accept 'Set Key Make and Break' commands
  hppa: Add support for LASI chip with i82596 NIC
  hw/hppa/dino.c: Improve emulation of Dino PCI chip
