Following patches aim to change ISA bus to a first-citizen class in Qemu.

They add ISA bus ops (like for scsi and usb buses), and use them to
remove the infamous isa_mem_base variable, which can't be changed after
startup.

Last two patches convert two ISA bridges to the new API. ISA bridges
used in MIPS/Malta and MIPS/fulong2e are not converted (yet).

Once all callers are converted, most of the work will be done to
support architectures with multiple ISA buses

Hervé Poussineau (6):
  isa: rename isa_bus_new to isa_bus_bridge_init
  isa: rework ISA bus internals, and add ISA bus ops structure
  isa: add isa_address_space() method
  vga: use isa_address_space() method
  isa: improve bus implementation of PIIX3 bridge
  isa: improve bus implementation of ebus bridge
