Artyom Tarasenko 3386376c04 Pad iommu with an empty slot (necessary for SunOS 4.1.4)
On the real hardware (SS-5, LX) the MMU is not padded, but aliased.
Software shouldn't use aliased addresses, neither should it crash
when it uses (on the real hardware it wouldn't). Using empty_slot
instead of aliasing can help with debugging such accesses.

Aurelien Jarno 409dbce54b load_elf: replace the address addend by a translation function
A few machines need to translate the ELF header addresses into physical
addresses. Currently the only possibility is to add a value to the
addresses.

This patch replaces the addend argument by and a translation function
and an opaque passed to the function. A NULL function does not translate
the address.

The patch also convert all machines that have an addend, simplify the
PowerPC kernel loading and fix the MIPS kernel loading using this new
feature. Other machines may benefit from this feature.

Gerd Hoffmann 3c178e72e0 rom loader: fix sparc -kernel boot.
Changes:
(1) register pstrcpy_targphys() in rom list, it is used for kernel
command lines by a number of architectures.
(2) add rom_ptr() function to get a pointer for applying changes
to loaded images.  Needed for example to tell the linux kernel
where it finds the initrd image by updating the header.
(3) make sparc use rom_ptr for initrd setup.

booting sparc-test works now, and 'info roms' shows this:

(qemu) info roms
addr=0000000000000000 size=0x2a3828 mem=ram name="phdr #0: vmlinux-2.6.11+tcx"
addr=00000000007ff000 size=0x00000e mem=ram name="cmdline"

reboot via 'system_reset' works too.

Markus Armbruster e23a1b33b5 New qdev_init_nofail()
Like qdev_init(), but terminate program via hw_error() instead of
returning an error value.

Use it instead of qdev_init() where terminating the program on failure
is okay, either because it's during machine construction, or because
we know that failure can't happen.

Because relying in the latter is somewhat unclean, and the former is
not always obvious, it would be nice to go back to qdev_init() in the
not-so-obvious cases, only with proper error handling.  I'm leaving
that for another day, because it involves making sure that error
values are properly checked by all callers.

Callers must pass ELF machine, byte swapping and symbol LSB clearing
information to ELF loader. A.out loader needs page size information, pass
that too as a parameter.

Extract prototypes to a separate file. Move loader.[ch] and elf_ops.h under hw.

Adjust callers. Also use target_phys_addr_t instead of target_ulong for

Gerd Hoffmann 81a322d4a1 qdev: add return value to init() callbacks.
Sorry folks, but it has to be.  One more of these invasive qdev patches.

We have a serious design bug in the qdev interface:  device init
callbacks can't signal failure because the init() callback has no
return value.  This patch fixes it.

We have already one case in-tree where this is needed:
Try -device virtio-blk-pci (without drive= specified) and watch qemu
segfault.  This patch fixes it.

With usb+scsi being converted to qdev we'll get more devices where the
init callback can fail for various reasons.

Blue Swirl 462eda24e5 Sparc32: improve interrupt handling
Level 15 interrupts are broadcast to all CPUs, each CPU can clear the
interrupt using the local Clear Pending register.

Update intbit_to_level table.

Don't try to raise level 0 interrupts.

Calculate pending interrupts based on the separate inputs from master
register. Setting or resetting the pending level isn't correct because of
overlap of levels.

Level 14 is always used for CPU timer interrupts, remove the property.

First step cleaning up the drives handling.  This one does nothing but
removing drives_table[], still it became seriously big.

drive_get_index() is gone and is replaced by drives_get() which hands
out DriveInfo pointers instead of a table index.  This needs adaption in
*tons* of places all over.

The drives are now maintained as linked list.

Gerd Hoffmann ee6847d19b qdev: rework device properties.
This patch is a major overhaul of the device properties.  The properties
are saved directly in the device state struct now, the linked list of
property values is gone.

Advantages:
  * We don't have to maintain the list with the property values.
  * The value in the property list and the value actually used by
    the device can't go out of sync any more (used to happen for
    the pci.devfn == -1 case) because there is only one place where
    the value is stored.
  * A record describing the property is required now, you can't set
    random properties any more.

There are bus-specific and device-specific properties.  The former
should be used for properties common to all bus drivers.  Typical
use case is bus addressing, i.e. pci.devfn and i2c.address.

Properties have a PropertyInfo struct attached with name, size and
function pointers to parse and print properties.  A few common property
types have PropertyInfos defined in qdev-properties.c.  Drivers are free
to implement their own very special property parsers if needed.

Properties can have default values.  If unset they are zero-filled.

Jan Kiszka 8217606e6e Introduce reset notifier order
Add the parameter 'order' to qemu_register_reset and sort callbacks on
registration. On system reset, callbacks with lower order will be
invoked before those with higher order. Update all existing users to the
standard order 0.

Note: At least for x86, the existing users seem to assume that handlers
are called in their registration order. Therefore, the patch preserves
this property. If someone feels bored, (s)he could try to identify this
dependency and express it properly on callback registration.
