[PATCH 00/21] hw: Let the machine be the owner of the system memory

[Philippe Mathieu-Daudé]

Hi,

This series is based on Igor's "eliminate remaining places that
abuse memory_region_allocate_system_memory()":
https://lists.gnu.org/archive/html/qemu-devel/2019-10/msg01601.html

It is quite simple, we enforce all machines to be the QOM owner
of the system memory.

This changes the memory tree from:

  (qemu) info mtree -o
  memory-region: pc.ram
    0000000000000000-0000000007ffffff (prio 0, ram): pc.ram parent:{obj 
path=/machine/unattached}

to:

  (qemu) info mtree -o
  memory-region: pc.ram
    0000000000000000-0000000007ffffff (prio 0, ram): pc.ram owner:{obj 
path=/machine}

Few patches are required to clean the codebase first, to unify the
creation of the system memory in the board/machine code. Mostly some
old ARM machines (pre-QOM) were affected.

Please review (as a generic codebase cleanup).

Regards,

Phil.
