[Qemu-devel] [PATCH V2 0/7] memory: unify ioport registration

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

This is the second version of patch serie (the previous patch was not split)
about ioport registration.

For the moment some part of QEMU use register_ioport* functions to register
ioport. These functions don't permit the logging of range with Memory Listener.

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

I may not to be aware about some new modifications (hw/dma.c and hw/apm.c),
any advice on its will be welcome.
