Since 39bffca2030950ef6efe57c2fac8327a45ae1015 (qdev: register all
types natively through QEMU Object Model), TypeInfo as used in
the common, non-iterative pattern is no longer amended with information
and should therefore be const.
Fix the documented QOM examples:
sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h
Since frequently the wrong examples are being copied by contributors of
new devices, fix all types in the tree:
sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c
sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c
This also avoids to piggy-back these changes onto real functional
changes or other refactorings.

pc_fw_add_pflash_drv() ignores qemu_find_file() failure, and happily
creates a drive without a medium.
When pc_system_flash_init() asks for its size, bdrv_getlength() fails
with -ENOMEDIUM, which isn't checked either. It fails relatively
cleanly only because -ENOMEDIUM isn't a multiple of 4096:
$ qemu-system-x86_64 -S -vnc :0 -bios nonexistant
qemu: PC system firmware (pflash) must be a multiple of 0x1000
[Exit 1 ]
Fix by handling the qemu_find_file() failure.

There are QEMUMachines that have neither IF_IDE nor IF_SCSI as a
default/standard interface to their block devices / drives. Therefore,
this patch introduces a new field default_block_type per QEMUMachine
struct. The prior use_scsi field becomes thereby obsolete and is
replaced through .default_block_type = IF_SCSI.
This patch also changes the default for s390x to IF_VIRTIO and
removes an early hack that converts IF_IDE drives.
Other parties have already claimed interest (e.g. IF_SD for exynos)
To create a sane default, for machines that dont specify a
default_block_type, this patch makes IF_IDE = 0 and IF_NONE = 1.
I checked all users of IF_NONE (blockdev.c and ww/device-hotplug.c)
as well as IF_IDE and it seems that it is ok to change the defines -
in other words, I found no obvious (to me) assumption in the code
regarding IF_NONE==0. IF_NONE is only set if there is an
explicit if=none. Without if=* the interface becomes IF_DEFAULT.
I would suggest to have some additional care, e.g. by letting
this patch sit some days in the block tree.
Based on an initial patch from Einar Lueck <elelueck@de.ibm.com>

Harmless, because we the error inevitably leads to another, fatal one
in pc_system_flash_init(): PC system firmware (pflash) not available.
Fix it anyway.

target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are
reserved) and its purpose doesn't match the name (most target_phys_addr_t
addresses are not target specific). Replace it with a finger-friendly,
standards conformant hwaddr.
Outstanding patchsets can be fixed up with the command
git rebase -i --exec 'find -name "*.[ch]"
| xargs s/target_phys_addr_t/hwaddr/g' origin

Valgrind reported this memory leak which occured a few times.
Test scenario:
qemu-system-i386 (no arguments), only BIOS started, terminate with

We're not actually calling qdev_init for the pc-sysfw device. Since we create
the canonical path during realize, this was causing an assert to trigger when
attempting to read a link pointing to pc-sysfw.

Now, the pc-sysfw:rom_only property will default
to false which enables flash by default.
All pc types below pc-1.1 set rom_only to true.
This prevents flash from being enabled on these
pc machine types.
For pc-1.1 rom_only will use the default (false),
which will allow flash to be used for pc-1.1.

Flash can be enabled by calling pc_system_firmware_init
with the system_flash_enabled parameter being non-zero.
If system_flash_enabled is zero, then the older qemu
rom creation method will be used.
If flash is enabled and a pflash image is found, then
it is used for the system firmware image.
If flash is enabled and a pflash image is not initially
found, then a read-only pflash device is created using
the -bios filename.
KVM cannot execute from a pflash region currently.
Therefore, when KVM is enabled, the old rom based
initialization method is used.
