Recent compilers can detect and inline manually-written bswap code,
but GCC 4.2.1 (the last GPLv2 version) cannot and generates really
awful code. Depending on how the compiler is configured, it might
also not want to generate bswap because it was not in i386. Using
asm is fine because TCG knows about bswap and all processors with
virtualization extensions also do.

The various host OSes are irritatingly variable about the name
of the linker emulation we need to pass to ld's -m option to
build the i386 option ROMs. Instead of doing this via a
CONFIG ifdef, check in configure whether any of the emulation
names we know about will work and pass the right answer through
to the makefile. If we can't find one, we fall back to not trying
to build the option ROMs, in the same way we would for a non-x86
host platform.
This is in particular necessary to unbreak the build on OpenBSD,
since it wants a different answer to FreeBSD and we don't have
an existing CONFIG_ variable that distinguishes the two.

Two fixes are needed. First, mingw does not have -D_FORTIFY_SOURCE,
hence --enable-debug disables optimization. This is not acceptable
for ROMs, which should override CFLAGS to force inclusion of -O2.
Second, PE stores global constructors and destructors using the
following linker script snippet:
___CTOR_LIST__ = .; __CTOR_LIST__ = . ;
LONG (-1);*(.ctors); *(.ctor); *(SORT(.ctors.*)); LONG (0);
___DTOR_LIST__ = .; __DTOR_LIST__ = . ;
LONG (-1); *(.dtors); *(.dtor); *(SORT(.dtors.*)); LONG (0);
The LONG directives cause the .img files to be 16 bytes too large;
the recently added check to signrom.py catches this. To fix this,
replace -T and -e options with a linker script.

When calling make with a CFLAGS=.. argument, the -g/-O filter is not
applied, which may result with build failure with ASAN for example. It
could be solved with an 'override' directive on CFLAGS, but that would
actually prevent setting different CFLAGS manually.
Instead, filter the CFLAGS argument from the top-level Makefile (so
you could still call make with a different CFLAGS argument on a
rom/Makefile manually)

Recent GCC compiles linuxboot_dma.c to 921 bytes, while CentOS 6 needs
1029 and clang needs 1527. Because the size of the ROM, rounded to the
next 512 bytes, must match, this causes the API to break between a <1K
ROM and one that is bigger.
We want to make the ROM 1.5 KB in size, but it's better to make clang
produce leaner ROMs, because currently it is worryingly close to the limit.
To fix this prevent clang's happy inlining (which -Os cannot prevent).
This only requires adding a noinline attribute.
Second, the patch makes sure that the ROM has enough padding to prevent
ABI breakage on different compilers. The size is now hardcoded in the file
that is passed to signrom.py, as was the case before commit 6f71b77
("scripts/signrom.py: Allow option ROM checksum script to write the size
header.", 2016-05-23); signrom.py however will still pad the input to
the requested size. This ensures that the padding goes beyond the
next multiple of 512 if necessary, and also avoids the need for
-fno-toplevel-reorder which clang doesn't support. signrom.py can then
error out if the requested size is too small for the actual size of the
compiled ROM.

The cc-option macro runs $(CC) in -S mode (generate assembly) to avoid a
pointless run of the assembler. However, this does not work when you want
to detect support for cc->as option passthrough. clang ignores -Wa unless
-c is provided, and exits successfully even if the -Wa,-32 option is not
supported.

There is ,bootindex=%d argument to specify the lookup order of
boot devices.
If a bootindex assigned to the device, then IPL Parameter Info Block
is created for that device when it is IPLed from.
If it is a mere SCSI device (not FCP), then IPIB is created with a
special SCSI type and its fields are used to store SCSI address of the
device. This new ipl block is private to qemu for now.
If the device to IPL from is specified this way, then SCSI bus lookup
is bypassed and prescribed devices uses the address specified.

To IPL from a device, pc-bios receives from qemu a device address via
general register 7. The better way to do it is to use diag308/6
instruction which returns so called
"IplParameterBlock". IplParameterBlock contains the device address for
IPL and additional parameters that can be used by pc-bios.
This patch allows pc-bios to get device address via diag308/6 and
doesn't use gr7 passed boot information anymore.

This is an s390 boot rom which was used in s390-virtio machine.
but since commit 3538fb6f89
"s390x: remove s390-virtio machine", this file isn't used.
The only place it is referenced in the code is an unused
define ZIPL_FILENAME. There's also comment in hw/s390/ipl.c
which I'm modifying too, to refer to s390-ccw.img instead.
