Convert the code to get 64-bit (unsigned long) values in the various
PDC functions. Output format strings need to change from %x to %lx.

Make functions which don't need to copy 64-bit return buffers back
to 32-bit callers with NO_COMPAT_RETURN_VALUE().

This option is only relevant when booting a 64-bit machine and the value
defaults to enabled (1).

When OS64 is set to 0, the firmware will tell the OS that 64-bit
firmware calls are not supported.

Effectively, this prevents the OS to install a 64-bit OS (on the 64-bit
machine).

We may trigger HPMCs (= trap #1) while probing various I/O addresses for

Fix crash when setting the PDC clock and running a 64-bit PDC in 32-bit
compat mode:
When writing the clock, no return values are returned to the caller as
there is no return buffer in ARG2. So this function needs to be marked
with NO_COMPAT_RETURN_VALUE(ARG2).

Signed-off-by: Helge Deller <deller@gmx.de>

Annotate a few more PDC calls with NO_COMPAT_RETURN_VALUE() to avoid
trashing their ARG2 value on return to caller in compat case.

Enhance the option to allow user to specify if 32-bit OS,
64-bit OS or both can be installed. The value reflects the

New & enhancements:
- Initial 64-bit firmware release
- Added fault handler to catch and report firmware bugs
- Use Qemu's builtin_console_out() via diag 0x101
- parisc-qemu-install Makefile target to install firmware in qemu
- Added -fw_cfg opt/OS64,string=3 option
- Machine definition files for 715/64, C8000, J6700 & rp3410

Fixes:
- Avoid crash when booting without SCSI controller
- Avoid possible crashes while detecting LASI LAN & graphics
- Don't check layers in PDC_MEM_MAP_HPA, fixes NetBSD
- Ensure cache definition does not trigger endless loops
- Mark B160L as 32-bit machine in inventory
