9584d3d00a build: disable fcf-protection on -march=486 -m16
Some of the roms build with -march=i486 -m16 which is incompatible
with -fcf-protection. That in turn is can be set by default, for
example in Ubuntu [1].
That causes:
 cc1: error: ‘-fcf-protection’ is not compatible with this target

This won't work on -march=i486 -m16 and no matter if set or not we can
override it to "none" if the option is known to the compiler to be
able to build reliably.

Fixes: https://gitlab.com/qemu-project/qemu/-/issues/889

a70248dbd3 configure: parse --enable/--disable-strip automatically, flip default
Always include the STRIP variable in config-host.mak (it's only used
by the s390-ccw firmware build, and it adds a default if configure
omitted it), and use meson-buildoptions.sh to turn
--enable/--disable-strip into -Dstrip.

The default is now not to strip the binaries like for almost every other
package that has a configure script.

fc8c745d50 spapr: Implement Open Firmware client interface
The PAPR platform describes an OS environment that's presented by
a combination of a hypervisor and firmware. The features it specifies
require collaboration between the firmware and the hypervisor.

Since the beginning, the runtime component of the firmware (RTAS) has
been implemented as a 20 byte shim which simply forwards it to
a hypercall implemented in qemu. The boot time firmware component is
SLOF - but a build that's specific to qemu, and has always needed to be
updated in sync with it. Even though we've managed to limit the amount
of runtime communication we need between qemu and SLOF, there's some,
and it has become increasingly awkward to handle as we've implemented
new features.

This implements a boot time OF client interface (CI) which is
enabled by a new "x-vof" pseries machine option (stands for "Virtual Open
Firmware). When enabled, QEMU implements the custom H_OF_CLIENT hcall
which implements Open Firmware Client Interface (OF CI). This allows
using a smaller stateless firmware which does not have to manage
the device tree.

The new "vof.bin" firmware image is included with source code under
pc-bios/. It also includes RTAS blob.

This implements a handful of CI methods just to get -kernel/-initrd
working. In particular, this implements the device tree fetching and
simple memory allocator - "claim" (an OF CI memory allocator) and updates
"/memory@0/available" to report the client about available memory.

This implements changing some device tree properties which we know how
to deal with, the rest is ignored. To allow changes, this skips
fdt_pack() when x-vof=on as not packing the blob leaves some room for
appending.

In absence of SLOF, this assigns phandles to device tree nodes to make
device tree traversing work.

When x-vof=on, this adds "/chosen" every time QEMU (re)builds a tree.

This adds basic instances support which are managed by a hash map
ihandle -> [phandle].

Before the guest started, the used memory is:
0..e60 - the initial firmware
8000..10000 - stack
400000.. - kernel
3ea0000.. - initramdisk

This OF CI does not implement "interpret".

Unlike SLOF, this does not format uninitialized nvram. Instead, this
includes a disk image with pre-formatted nvram.

With this basic support, this can only boot into kernel directly.
However this is just enough for the petitboot kernel and initradmdisk to
boot from any possible source. Note this requires reasonably recent guest
kernel with:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=df5be5be8735

The immediate benefit is much faster booting time which especially
crucial with fully emulated early CPU bring up environments. Also this
may come handy when/if GRUB-in-the-userspace sees light of the day.

This separates VOF and sPAPR in a hope that VOF bits may be reused by
other POWERPC boards which do not support pSeries.

This assumes potential support for booting from QEMU backends
such as blockdev or netdev without devices/drivers used.

a5b2afd522 pc-bios/s390-ccw: Allow building with Clang, too
Clang unfortunately does not support generating code for the z900
architecture level and starts with the z10 instead. Thus to be able
to support compiling with Clang, we have to check for the supported
compiler flags. The disadvantage is of course that the bios image
will only run with z10 guest CPUs upwards (which is what most people
use anyway), so just in case let's also emit a warning in that case
(we will continue to ship firmware images that have been pre-built
with GCC in future releases, so this should not impact normal users,
too).

The offending code is:

  memset((char *)S390EP, 0, 6);

where S390EP is a const address:

  #define S390EP 0x10008

The compiler doesn't know how big that pointed area is, so it assume that
its length is zero. This has been reported as BZ#99578 to GCC:
"gcc-11 -Warray-bounds or -Wstringop-overread warning when accessing a
pointer from integer literal"
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99578

As this warning does us more harm than good in the BIOS code (where
lot of direct accesses to low memory are done), silence this warning
for all BIOS objects.

3462ff3551 pc-bios/s390-ccw: Fix the cc-option macro in the Makefile
The cc-option macro is not doing what it should - compared with the
original from the rules.mak file that got removed with commit
660f793093 ("Makefile: inline the relevant parts of rules.mak"),
the arguments got changed and thus the macro is rather doubling
the QEMU_CFLAGS than adding the flag that should be tested.

679196a646 pc-bios/s390-ccw: Silence warning from Clang by marking panic() as noreturn
When compiling the s390-ccw bios with Clang, the compiler emits a warning:

 pc-bios/s390-ccw/main.c:210:5: warning: variable 'found' is used uninitialized
  whenever switch default is taken [-Wsometimes-uninitialized]
     default:
     ^~~~~~~
 pc-bios/s390-ccw/main.c:214:16: note: uninitialized use occurs here
     IPL_assert(found, "Boot device not found\n");
                ^~~~~

It's a false positive, it only happens because Clang is not smart enough
to see that the panic() function in the "default:" case can never return.

Anyway, let's explicitely mark panic() with "noreturn" to shut up the
warning.

b460a22087 pc-bios/s390-ccw/netboot: Use "-Wl," prefix to pass parameter to the linker
We are using the compiler to do the linking of the bios files. GCC still
accepts the "-Ttext=..." linker flag directly and is smart enough to
pass it to the linker, but in case we are compiling with Clang, we have
to use the official way with the "-Wl," prefix instead.

ff77712a8a pc-bios/s390-ccw: Use reset_psw pointer instead of hard-coded null pointer
When compiling the s390-ccw bios with clang, it emits a warning like this:

 pc-bios/s390-ccw/jump2ipl.c:86:9: warning: indirection of non-volatile null
  pointer will be deleted, not trap [-Wnull-dereference]
     if (*((uint64_t *)0) & RESET_PSW_MASK) {
         ^~~~~~~~~~~~~~~~
 pc-bios/s390-ccw/jump2ipl.c:86:9: note: consider using __builtin_trap() or
  qualifying pointer with 'volatile'

We could add a "volatile" here to shut it up, but on the other hand,
we also have a pointer variable called "reset_psw" in this file already
that points to the PSW at address 0, so we can simply use that pointer
variable instead.

d08a649404 pc-bios/s390-ccw/bootmap: Silence compiler warning from Clang
When compiling the s390-ccw bios with Clang, the compiler complains:

 pc-bios/s390-ccw/bootmap.c:302:9: warning: logical not is only applied
  to the left hand side of this comparison [-Wlogical-not-parentheses]
    if (!mbr->dev_type == DEV_TYPE_ECKD) {
        ^              ~~

The code works (more or less by accident), since dev_type can only be
0 or 1, but it's better of course to use the intended != operator here
instead.

335b638937 roms/u-boot: Bump ppce500 u-boot to v2021.04 to fix broken pci support
When QEMU originally supported the ppce500 machine back in Jan 2014,
it was created with a 1:1 mapping of PCI bus address. Things seemed
to change rapidly that in Nov 2014 with the following QEMU commits:

commit e6b4e5f479 ("PPC: e500: Move CCSR and MMIO space to upper end of address space")

and

commit cb3778a045 ("PPC: e500 pci host: Add support for ATMUs")

the PCI memory and IO physical address were moved to beyond 4 GiB,
but PCI bus address remained below 4 GiB, hence a non-identity
mapping was created. Unfortunately corresponding U-Boot updates
were missed along with the QEMU changes and the U-Boot QEMU ppce500
PCI support has been broken since then, until this issue was fixed
recently in U-Boot mainline v2021.04 release, specifically by the
following U-Boot series:

http://patchwork.ozlabs.org/project/uboot/list/?series=230985&state=*

The cross-compilation toolchain used to build the U-Boot image is:
https://mirrors.edge.kernel.org/pub/tools/crosstool/files/bin/x86_64/10.1.0/x86_64-gcc-10.1.0-nolibc-powerpc-linux.tar.xz
