New:
- Added new "715" machine (Snake machine, no PCI bus)
- Added driver for NCR710 SCSI on LASI (Soumyajyotii Ssarkar)
Fixes & cleanups:
- Fix memory size detection on NetBSD
- Snake machines do not support the PDC_SYSTEM_MAP call
- Always return the HPA in pdc_mem_map() PDC call
- Add LMMIO range for internal artist graphic card
- various coding style cleanups

- we need different CPU HPA offsets on 715, and can only support up to 8
CPUs
- on a 64-bit machine, never always fall back to B160L and not to 715
when asking for model from 32-bit PDC call from OS
- old machines like 715 do not support the PDC_SYSTEM_MAP call, so fall
back to Snake detection on those.

NetBSD showed the memory size of the first memory module wrong.
It turns out that our PDC_IODC_NINIT call did not returned the
expected value in the second result word.

A driver for the NCR 53C710 SCSI chip, as used in PA-RISC and other

This driver has been developed during the Google Summer of Code 2025
program.

On the HP 715 machine the base address of the LASI controller is
at 0xf0100000, so introduce a constant for this address.
The firmware end address needs to be reduced to not overlap with
the LASI addresses.
Introduce LASI_XXX constants which reflects the offsets of the
various devices of the LASI base HPA.
Adjust the serial port addressess accordingly. We can not use hard
coded HPAs, because on 715 the LASI serial ports are at different
addresses than on B160L.

When the target has sent its MESSAGE IN phase data to the initiator, it waits
for the initiator to release the ACK signal before disconnecting from the bus.
Send a MSG_ACC command to the ESP so that the initiator releases the ACK signal
to allow the target to disconnect, and also return the ASC back to the
disconnected state.

The MPE IPL boot loader calls PDC_MODEL when running in narrow mode.
The return buffer pointed to by arg2 holds space for eigth 32-bit integers
directly followed by the stack used by MPE.
So, when pdc_model() writes 32 64-bit integers to arg2, it unintentionally
overwrites MPE's call stack.
Fix it by limiting returned bytes depending if PDC_MODEL was called
in WIDE or NARROW mode.
Signed-off-by: Helge Deller <deller@gmx.de>
Some PDC functions need to know at runtime if they were called in
narrow mode. Add infrastructure to hand over this information to
parisc_pdc_entry().
The background is, that the MPE IPL boot loader calls PDC_MODEL
and provides a very small return buffer, followed in memory by the
stack. So, when pdc_model writes 32 x 8 bytes in 64-bit mode,
the stack of IPL boot will be trashed.
Signed-off-by: Helge Deller <deller@gmx.de>
This parameter was intended to make sure that the compiler saves
registers on the stack and prevents possible register corruption.
But this isn't needed and doesn't help, so just remove it.

HP-UX 11.x (64-bit) seems to require memory-mapped serial ports when accessing
GSP cards, so change the firmware to pre-map serial ports for memory-accesses.
