target/hppa: Fix boot and reboot for SMP machines
Fix some SMP-related boot and reboot issues with HP-UX and Linux by
correctly initializing the CPU PSW bits, disabling data and instruction
translations and unhalting the CPU in the qemu hppa_machine_reset()
function.
To work correctly some fixes are needed in the SeaBIOS-hppa firmware too,
which is why this series updates it to version 8 which includes those
fixes and enhancements:
Fixes
- boot of HP-UX with SMP, and
- reboot of Linux and HP-UX with SMP
Enhancements:
- show qemu version in boot menu
- adds exit menu entry in boot menu to quit emulation
- allow to trace PCD_CHASSIS codes more specifically
