[Qemu-devel] [PATCH V8 0/8] memory: unify ioport registration

[Julien Grall <julien.grall@citrix.com>]

This is the eighth version of patch series about ioport registration.

Some part of QEMU still use register_ioport* functions to register ioport.
These functions doesn't allow to use Memory Listener on it.

Modifications between V1 and V2:
   - Remove the use of get_system_io. Instead of use isa and pci IO
     address space;
   - Avoid allocation of PortioList. Use the different device
     structure;
   - Still remove register_ioport* (hw/dma.c, hw/apm.c, hw/acpi_piix4.c);
   - Use MemoryRegion when we have only a range of ioport;
   - For some functions, add IO address space as argument;
   - Add isa_address_space_io function.

Modifications between V2 and V3:
   - Remove some register_ioport_* on hw/vt82c686.c;
   - Split smb ioport part in new patch;
   - Still replace MemoryRegion when we have only a range of ioport;
   - Fix read/write ioports prototype to  be compliant with memory callback.

Modifications between V3 and V4:
   - Fix compilation in hw/dma.c;
   - Fix address conversion (hw/dma.c, hw/acpi_piix4.c) with MemorySection.
     Indeed the new version use offset from MemorySection start instead of 0.

Modifications between V4 and V5:
   - Rebase on qemu upstream;
   - Forget some ioport_register_* in acpi_piix4.c;
   - Register 0x3b0 - 0x3df range for cirrus instead of ioport by ioport.

Modifications between V5 and V6:
   - Add read function on cirrus ioport (forget on the previous patch);
   - Rework PM memory range handling;
   - Fix PCI_BASE in acpi_piix4.c (wrong conversion during port);
   - Rewrite isa_address_space_io to use ISA bus address space;
   - Fix compilation in vt82c686.c.

Modifications between V6 and V7:
   - acpi_piix4: use memory_region_set_enabled instead of a boolean. I'm not
     sure about this modification (adviced by Avi);
   - Fix device endianness in acpi_piix4 (reported by Avi);
   - Avoid dependencies between patches and reorder it (reported by Jan).
     Some code moved from acpi_piix4 patch to smb/apm patches;

Modifications between V7 and V8:
   - Fix device endianness in smb patch, I forgot some on previous version;
   - Register pm io region at initialization with default value instead
     of at first call to pm_io_space_update (reported by Jan).
