[PATCH v2 0/9] target/hppa qemu v8.2 regression fixes

[deller@kernel.org]

From: Helge Deller <deller@gmx.de>

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)

I tried to keep the patches small to make backporting easier.

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.

The whole series can be pulled from the "hppa-fixes-8.2" branch from:
https://github.com/hdeller/qemu-hppa.git        hppa-fixes-8.2

Changes v1->v2:
- fix OpenBSD boot with SeaBIOS v15 instead of v14
- commit message enhancements suggested by BALATON Zoltan
- use uint64_t for ram_max in patch #1
