  target/hppa: Update SeaBIOS-hppa to version 15 (2024-01-07 09:13:07 +0100)

----------------------------------------------------------------
target/hppa qemu v8.2 regression fixes

There were some regressions introduced with Qemu v8.2 on the hppa/hppa64
target, e.g.:

- 32-bit HP-UX crashes on B160L (32-bit) machine
- NetBSD boot failure due to power button in page zero
- NetBSD FPU detection failure
- OpenBSD 7.4 boot failure

This small patch series fixes those known regressions and
additionally:

- allows usage of the max. 3840MB of memory (instead of 3GB),
- adds support for the qemu --nodefaults option (to debug other devices)

This patch set will not fix those known (non-regression) bugs:
- HP-UX and NetBSD still fail to boot on the new 64-bit C3700 machine
- Linux kernel will still fail to boot on C3700 as long as kernel modules are used.

----------------------------------------------------------------

Helge Deller (9):
  hw/hppa/machine: Allow up to 3840 MB total memory
  hw/hppa/machine: Disable default devices with --nodefaults option
  hw/pci-host/astro: Add missing astro & elroy registers for NetBSD
  target/hppa: Fix PDC address translation on PA2.0 with PSW.W=0
  target/hppa: Strip upper 32-bits of IOR on error in probe
  target/hppa: Strip upper 32-bits of IOR on unaligned access error
  hw/hppa: Move software power button address back into PDC
  target/hppa: Avoid accessing %gr0 when raising exception
  target/hppa: Update SeaBIOS-hppa to version 15

I believe at least one of these patches to be wrong.
Please do not pull right now.
