Revert "ide save/restore pio/atapi cmd transfer fields and io buffer"
This reverts commit ed487bb1d69040b9dac64a4fc076d8dd82b131d6.
The conflicts are due to commit 4fc8d6711aff7a9c11e402c3d77b481609f9f486that is a fix to the ide_drive_pre_save() function. It reverts both...
ide: Replace IDEState members is_cdrom, is_cf by drive_kind
The two aren't independent variables. Make that obvious.

ide: Make ide_init_drive() return success
It still always succeeds. The next commits will add failures.
qdev: Decouple qdev_prop_drive from DriveInfo
Make the property point to BlockDriverState, cutting out the DriveInfomiddleman. This prepares the ground for block devices that don't havea DriveInfo.
Currently all user-defined ones have a DriveInfo, because the only way...
ide: Remove useless IDEDeviceInfo members unit, drive
ide: Remove redundant IDEState member conf
Commit 428c149b added IDEState member conf to let commit 0009baf1 findthe BlockConf from there. It exists only for qdev drives, created viaide_drive_initfn(), not for drives created via ide_init2().
But for a qdev drive, we can just as well reach its IDEDevice, which...
ide: Split non-qdev code off ide_init2()
ide: Turn drive serial into a qdev property ide-drive.serial
It needs to be a qdev property, because it belongs to the drive'sguest part.
Bonus: info qtree now shows the serial number.
cmd646: pass pci_dev as it needs it
Instead of doing tricks to get the pci_dev, just pass it in the 1stplace. Patch is a bit longer that reverting the pci_dev field, but itstates more clearly (IMHO) what we are doing.
It also fixes the bm test, now that you told me that ->unit is not...

block: add topology qdev properties
Add three new qdev properties to export block topology information tothe guest. This is needed to get optimal I/O alignment for RAID arraysor SSDs.
The options are:
- physical_block_size to specify the physical block size of the device,...
ide: device version property
This patch adds a new property named 'ver' to ide-drive which allows tospecify the version which the virtual disk/cdrom should report to theguest. By default this is the qemu version (i.e. 0.12). usage:
-drive if=none,id=disk,file=......
workaround for cmd646 bmdma register access while no dma is active
This is a workaround only, and is a partial revertof a few changes to BMDMAState which removed pci_devfield on the way.

Problem: x86 systems could not survive a few system_resets.
Clear most of IDE state when reset. Implement the missing reset handlers.

split away drive init from ide_init2()
This allows the ide bus being initialized without drives attachedand the drives being attached and initialization later on asseparate step.
ide: pass down DriveInfo instead of BlockDriverState
ide: move cmd+irq from IDEState to IDEBus.
These variables are per bus, not per drive. Lets move them andcleanup things a bit. And fix the cmd migration bug for real.
