crashes when the code tries to access the wrong ring data).

Commit bb185de423 ("s390x: Add individual loadparm assignment to

of the machine value, however, when no boot devices are defined, the machine
loadparm becomes ignored. Therefore, let's check the machine loadparm
prior to probing the devices.

target/hppa: Update SeaBIOS-hppa to version 17

This is SeaBIOS for the hppa architecture v17.
If comes with some important firmware and SCSI fixes and
prepares for futher development to support 64-bit HP-UX
and MPE/UX in the future.

New PDC functions & general enhancements:
- Add PDC_MODEL_GET_INSTALL_KERNEL firmware call
- Add PDC_PAT_EVENT firmware call
- Support ENTRY_IO_BOOTOUT
- Prefer memory-access over io-access of GSP serial port
- Disable LMMIO_DIRECT0 range during modification
- Small optimizations in IODC call

Fixes:
- esp-scsi: indicate acceptance of MESSAGE IN phase data
- Avoid crash when booting without SCSI controller
- Remove exec flag from hppa-firmware.img
- Fix LMMIO detection for PCI cards on Astro/Elroy
- Avoid trashing MPE IPL bootloader stack
- HP-UX 11 64-bit saves number of RAM pages in PAGE0 at 0x33c
- Fix return value of PDC_CACHE/PDC_CACHE_RET_SPID for space id hashing
- Allow PDC functions to act when called in narrow mode
- pcidevice: Use portaddr_t for io port addresses

Cleanups:
- Change default make target to "parisc"
- Clean the "out-64" directory on "make clean"

pc-bios/s390-ccw: Don't generate TEXTRELs

Commit 7cd50cbe4ca3 ("pc-bios/s390-ccw: Don't use __bss_start with the
"larl" instruction") introduced the address constant bss_start_literal
for __bss_start in the .text section, which introduced a relocation in
code (i.e. TEXTREL). The dedicated constant is required, as __bss_start
may not necessarily be aligned on a 2-byte boundary (see subject commit
for details).

Move the constant to the .data section to get rid of the relocation in
the .text section. Add the linker option -z text to prevent TEXTRELs to
get introduced in the future.

Note that the R_390_RELATIVE relocations are taken care of by function
glue() in include/hw/elf_ops.h.inc introduced by commit 5dce07e1cb67
("elf-loader: Provide the possibility to relocate s390 ELF files").

s390x: Rebuild IPLB for SCSI device directly from DIAG308

Because virtio-scsi type devices use a non-architected IPLB pbt code they cannot
be set and stored normally. Instead, the IPLB must be rebuilt during re-ipl.

As s390x does not natively support multiple boot devices, the devno field is
used to store the position in the boot order for the device.

Handling the rebuild as part of DIAG308 removes the need to check the devices
for invalid IPLBs later in the IPL.

s390x: Add individual loadparm assignment to CCW device

Add a loadparm property to the VirtioCcwDevice object so that different
loadparms can be defined on a per-device basis for CCW boot devices.

The machine/global loadparm is still supported. If both a global and per-device
loadparm are defined, the per-device value will override the global value for
that device, but any other devices that do not specify a per-device loadparm
will still use the global loadparm.

It is invalid to assign a loadparm to a non-boot device.

We originally built a separate binary for the netboot code since it

necessary SLOF module had been checked out. Time passed, the code
proved its usefulness, and the build system nowadays makes sure that
the SLOF module is checked out if you have a s390x compiler available
for building the s390-ccw bios. So there is no real compelling reason
anymore to keep the netboot code in a separate binary. Linking the
code together with the main s390-ccw.img will make future enhancements
much easier, like supporting more than one boot device.

We are already using the libc from SLOF for the s390-netboot.img, and

Since we are now always assuming that the SLOF submodule is available
when building the s390-ccw bios (see commit bf6903f6944f), we can drop
the simple implementation and use the SLOF libc for the s390-ccw.img
binary, too.

Additionally replace sclp_print calls with puts/printf now that it is
available.
