c6ff8bde8d hw/ide: Remove last two uses of ide/internal.h outside of hw/ide/
Remove last two includes of hw/ide/intarnal.h outside of hw/ide and
replace them with newly added public header to allow moving internal.h
into hw/ide to really stop exposing it.

a11f439a0e hw/ide: Stop exposing internal.h to non-IDE files
include/hw/ide/internal.h is currently included by include/hw/ide/pci.h
and thus exposed to a lot of files that are not part of the IDE subsystem.
Stop including internal.h there and use the appropriate new headers
ide-bus.h and ide-dma.h instead.

bd217d88dc hw/ide: Add the possibility to disable the CompactFlash device in the build
For distros like downstream RHEL, it would be helpful to allow to disable
the CompactFlash device. For making this possible, we need a separate
Kconfig switch for this device, and the code should reside in a separate
file. Let's also introduce a new header ide-dev.h which can be used to
collect definitions related to IDE devices.

fd6a543d19 ide/pci: introduce pci_ide_update_mode() function
This function reads the value of the PCI_CLASS_PROG register for PCI IDE
controllers and configures the PCI BARs and/or IDE ioports accordingly.

In the case where we switch to legacy mode, the PCI BARs are set to return zero
(as suggested in the "PCI IDE Controller" specification), the legacy IDE ioports
are enabled, and the PCI interrupt pin cleared to indicate legacy IRQ routing.

Conversely when we switch to native mode, the legacy IDE ioports are disabled
and the PCI interrupt pin set to indicate native IRQ routing. The contents of
the PCI BARs are unspecified, but this is not an issue since if a PCI IDE
controller has been switched to native mode then its BARs will need to be
programmed.

edf5ca5dbe include/hw/pci: Split pci_device.h off pci.h
PCIDeviceClass and PCIDevice are defined in pci.h.  Many users of the
header don't actually need them.  Similar structs live in their own
headers: PCIBusClass and PCIBus in pci_bus.h, PCIBridge in
pci_bridge.h, PCIHostBridgeClass and PCIHostState in pci_host.h,
PCIExpressHost in pcie_host.h, and PCIERootPortClass, PCIEPort, and
PCIESlot in pcie_port.h.

Move PCIDeviceClass and PCIDeviceClass to new pci_device.h, along with
the code that needs them.  Adjust include directives.

This also enables the next commit.

176e4961bb hw/ide/core.c: Implement ATA INITIALIZE_DEVICE_PARAMETERS command
CHS-based disk utilities and operating systems may adjust the logical
geometry of a hard drive to cope with the expectations or limitations
of software using the ATA INITIALIZE_DEVICE_PARAMETERS command.

Prior to this patch, INITIALIZE_DEVICE_PARAMETERS was a nop that
always returned success, raising the possibility of data loss or
corruption if the CHS<->LBA translation redirected a write to the
wrong sector.

* hw/ide/core.c
ide_reset():
  Reset the logical CHS geometry of the hard disk when the power-on
  defaults feature is enabled.
cmd_specify():
  a) New function implementing INITIALIZE_DEVICE_PARAMETERS.
  b) Ignore calls for empty or ATAPI devices.
cmd_set_features():
  Implement the power-on defaults enable and disable features.
struct ide_cmd_table:
  Switch WIN_SPECIFY from cmd_nop() to cmd_specify().
ide_init_drive():
  Set new fields 'drive_heads' and 'drive_sectors' based upon the
  actual disk geometry.

* include/hw/ide/internal.h
struct IDEState:
a) Store the actual drive CHS values within the new fields
   'drive_heads' and 'drive_sectors.'
b) Track whether a soft IDE reset should also reset the logical CHS
   geometry of the hard disk within the new field 'reset_reverts'.

9405d87be2 hw/ide: Fix crash when plugging a piix3-ide device into the x-remote machine
QEMU currently crashes when the user tries to do something like:

 qemu-system-x86_64 -M x-remote -device piix3-ide

This happens because the "isabus" variable is not initialized with
the x-remote machine yet. Add a proper check for this condition
and propagate the error to the caller, so we can fail there gracefully.

0c7515e1c4 ide: remove magic constants from the device register
(In QEMU, we call this the "select" register.)

My memory isn't good enough to memorize what these magic runes
do. Label them to prevent mixups from happening in the future.

Side note: I assume it's safe to always set 0xA0 even though ATA2 claims
these bits are reserved, because ATA3 immediately reinstated that these
bits should be always on. ATA4 and subsequent specs only claim that the
fields are obsolete, so I assume it's safe to leave these set and that
it should work with the widest array of guests.

be8c9423de ide: model HOB correctly
I have been staring at this FIXME for years and I never knew what it
meant. I finally stumbled across it!

When writing to the command registers, the old value is shifted into a
HOB copy of the register and the new value is written into the primary
register. When reading registers, the value retrieved is dependent on
the HOB bit in the CONTROL register.

By setting bit 7 (0x80) in CONTROL, any register read will, if it has
one, yield the HOB value for that register instead.

Our code has a problem: We were using bit 7 of the DEVICE register to
model this. We use bus->cmd roughly as the control register already, as
it stores the value from ide_ctrl_write.

Lastly, all command register writes reset the HOB, so fix that, too.

db1015e92e Move QOM typedefs and add missing includes
Some typedefs and macros are defined after the type check macros.
This makes it difficult to automatically replace their
definitions with OBJECT_DECLARE_TYPE.

Patch generated using:

 $ ./scripts/codeconverter/converter.py -i \
   --pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]')

which will split "typdef struct { ... } TypedefName"
declarations.

Followed by:

 $ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \
    $(git grep -l '' -- '*.[ch]')

which will:
- move the typedefs and #defines above the type check macros
- add missing #include "qom/object.h" lines if necessary
