Please pull from
    https://github.com/hdeller/qemu-hppa.git target-hppa
to fix those bugs in target-hppa:

* Fix the SeaBIOS-hppa firmware build with gcc-10 on Debian

* Fix the SeaBIOS-hppa firmware to boot NetBSD again

* Fix many artist framebuffer out-of-bounds accesses as found by Alexander Bulekov

* Fix artist memory access bugs due to commit 5d971f9e6725 ("memory: Revert
  "memory: accept mismatching sizes in memory_region_access_valid")

* Fix various artist screen updates when running dtwm on HP-UX

In addition the SeaBIOS-hppa firmware now includes a version check to prevent
starting when it's incompatible to the emulated qemu hardware.

Thanks,
Helge
