[PATCH v3 00/25] hw: Sanitize various MemoryRegion calls

[Philippe Mathieu-Daudé]

This series simplifies various memory API calls when creating
memory regions.

Most of the patches are generated with Coccinelle semantic
patches (provided).
Few more cleanups added while writting the patches have been
added.

v1 was 'Let devices own the MemoryRegion they create':
https://www.mail-archive.com/address@hidden/msg681960.html

Since v2:
- only keep generated/automatic patches
- add reviewers tags

Since v1:
- understood a bit more Peter Maydell comments regarding
  how memory devices are migrated.

Philippe Mathieu-Daudé (25):
  memory: Correctly return alias region type
  memory: Simplify memory_region_init_rom_nomigrate() to ease review
  scripts/cocci: Rename memory-region-{init-ram -> housekeeping}
  scripts/cocci: Patch to replace memory_region_init_{ram,readonly ->
    rom}
  hw/arm: Use memory_region_init_rom() with read-only regions
  hw/display: Use memory_region_init_rom() with read-only regions
  hw/m68k: Use memory_region_init_rom() with read-only regions
  hw/net: Use memory_region_init_rom() with read-only regions
  hw/pci-host: Use memory_region_init_rom() with read-only regions
  hw/ppc: Use memory_region_init_rom() with read-only regions
  hw/riscv: Use memory_region_init_rom() with read-only regions
  hw/sh4: Use memory_region_init_rom() with read-only regions
  hw/sparc: Use memory_region_init_rom() with read-only regions
  scripts/cocci: Patch to detect potential use of memory_region_init_rom
  scripts/cocci: Patch to remove unnecessary
    memory_region_set_readonly()
  scripts/cocci: Patch to let devices own their MemoryRegions
  hw/core: Let devices own the MemoryRegion they create
  hw/display: Let devices own the MemoryRegion they create
  hw/dma: Let devices own the MemoryRegion they create
  hw/riscv: Let devices own the MemoryRegion they create
  hw/char: Let devices own the MemoryRegion they create
  hw/arm/stm32: Use memory_region_init_rom() with read-only regions
  hw/ppc/ppc405: Use memory_region_init_rom() with read-only regions
  hw/arm: Remove unnecessary memory_region_set_readonly() on ROM alias
  hw/arm: Let devices own the MemoryRegion they create
