This is to allow us to decouple the DINO device from the board logic. The choice
of using a hard-coded constant (along with a comment) is to match how this is
already done for toc_addr. If it is decided later that these values need to be

DINO refers to the GSC-PCI bridge device which will soon be handled separately,
however the QEMU HPPA machine is actually based upon the HPPA B160L as indicated
by the Linux kernel dmesg output when booted in qemu-system-hppa and the QEMU
MAINTAINERS file.

Update the machine configuration to use CONFIG_HPPA_B160L instead of CONFIG_DINO
and also update the machine description accordingly.

4a4554c6c5 hppa: Add support for an emulated TOC/NMI button. 
Almost all PA-RISC machines have either a button that is labeled with 'TOC' or
a BMC/GSP function to trigger a TOC.  TOC is a non-maskable interrupt that is
sent to the processor.  This can be used for diagnostic purposes like obtaining
a stack trace/register dump or to enter KDB/KGDB in Linux.

This patch adds support for such an emulated TOC button.

It wires up the qemu monitor "nmi" command to trigger a TOC.  For that it
provides the hppa_nmi function which is assigned to the nmi_monitor_handler
function pointer.  When called it raises the EXCP_TOC hardware interrupt in the
hppa_cpu_do_interrupt() function.  The interrupt function then calls the
architecturally defined TOC function in SeaBIOS-hppa firmware (at fixed address
0xf0000000).

According to the PA-RISC PDC specification, the SeaBIOS firmware then writes
the CPU registers into PIM (processor internal memmory) for later analysis.  In
order to write all registers it needs to know the contents of the CPU "shadow
registers" and the IASQ- and IAOQ-back values. The IAOQ/IASQ values are
provided by qemu in shadow registers when entering the SeaBIOS TOC function.
This patch adds a new aritificial opcode "getshadowregs" (0xfffdead2) which
restores the original values of the shadow registers. With this opcode SeaBIOS
can store those registers as well into PIM before calling an OS-provided TOC
handler.

To trigger a TOC, switch to the qemu monitor with Ctrl-A C, and type in the
command "nmi".  After the TOC started the OS-debugger, exit the qemu monitor
with Ctrl-A C.

87e126ea14 hw/hppa: Allow up to 16 emulated CPUs 
This brings the hppa_hardware.h file in sync with the copy in the
SeaBIOS-hppa sources.

In order to support up to 16 CPUs, it's required to move the HPA for
MEMORY_HPA out of the address space of the new 16th CPU.
The new address of 0xfffff000 worked well for Linux and HP-UX, while
other addresses close to the former 0xfffbf000 area are used by the
architecture for local and global broadcasts.

The PIM_STORAGE_SIZE constant is used in SeaBIOS sources and
is relevant for the TOC/NMI feature.

e06054368c hw: Remove superfluous includes of hw/hw.h 
The include/hw/hw.h header only has a prototype for hw_error(),
so it does not make sense to include this in files that do not
use this function.

db1015e92e Move QOM typedefs and add missing includes 
Some typedefs and macros are defined after the type check macros.
This makes it difficult to automatically replace their
definitions with OBJECT_DECLARE_TYPE.

Patch generated using:

 $ ./scripts/codeconverter/converter.py -i \
   --pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]')

which will split "typdef struct { ... } TypedefName"
declarations.

Followed by:

 $ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \
    $(git grep -l '' -- '*.[ch]')

which will:
- move the typedefs and #defines above the type check macros
- add missing #include "qom/object.h" lines if necessary

34743e9633 hw/hppa: Change fw_cfg port address 
Devices on hppa occupy at least 4k starting at the HPA, so MEMORY_HPA+4k is
blocked (by Linux) for the memory module.  I noticed this when testing the new
Linux kernel patch to let the fw_cfg entries show up in Linux under /proc.
The Linux kernel driver could not allocate the region for fw_cfg.
This new base address seems to not conflict.

df5c6a5094 hw/hppa: Make number of TLB and BTLB entries configurable 
Until now the TLB size was fixed at 256 entries. To allow operating
systems to utilize more TLB entries in the future, we need to tell
firmware how many TLB entries we actually support in the emulation.
Firmware then reports this to the operating system via the
PDC_CACHE_INFO call.

This patch simply does the preparation to allow more TLB entries.
