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.

245760074a hw/hppa: Tell SeaBIOS port address of fw_cfg
Change QEMU_FW_CFG_IO_BASE to shorter variant FW_CFG_IO_BASE and hand
over the actual port address in %r19 to SeaBIOS.

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.

4765384ce3 hppa: Add emulation of Artist graphics
This adds emulation of Artist graphics good enough to get a text
console on both Linux and HP-UX. The X11 server from HP-UX also works.

Adjust boot-serial-test to disable graphics, so that SeaBIOS outputs
to the serial port, as expected by the test.

2b42f31eae Update seabios-hppa to latest upstream
This patch fixes two issues in the hppa/parisc emulation:

1. The CPU HPA was wrong in the sense that we had negative module
offsets in the firmware-internal module table (which we ignored up to
now). Get it correct by changing the CPU HPA to 0xfffb0000 which is
greater than the DINO_HPA of 0xfff80000.
This change requires the seabios-firmware update.

2. Sven noticed that the FPU register cr10 is only able to reference up
to 8 FPUs, so let's reduce the maximum amount of SMP CPUs too.

a72bd606ca hw/hppa: Implement DINO system board
Now that we have the prerequisites in target/hppa/,
implement the hardware for a PA7100LC.

This also enables build for hppa-softmmu.
