Paolo Bonzini d8d9581460 memory: convert memory_region_destroy to object_unparent
Explicitly call object_unparent in the few places where we
will re-create the memory region.  If the memory region is
simply being destroyed as part of device teardown, let QOM
handle it.

Hu Tao e206ad4833 ppc: fix -mem-path failure
commit e938ba0c tried to enable -mem-path for ppc but breaked some ppc
boards.

The problems are:

1. it fails when allocating memory for rom, sram whose sizes are less
   than huge page size:

   ./ppc-softmmu/qemu-system-ppc  -m 512 -mem-path /hugepages/ \
   -kernel /home/hutao/Downloads/vmlinux-ppc -initrd \
   /home/hutao/Downloads/initrd-ppc.gz
   qemu-system-ppc: /mnt/data/projects/qemu/exec.c:1184: qemu_ram_set_idstr: Assertion `new_block' failed.

2. if there is a numa node backed by memory backend object, qemu fails
   with message:

   ./ppc-softmmu/qemu-system-ppc  -m 512 \
   -object memory-backend-file,size=512M,mem-path=/hugepages,id=f0 \
   -numa node,nodeid=0,memdev=f0 \
   -kernel /home/hutao/Downloads/vmlinux-ppc \
   -initrd /home/hutao/Downloads/initrd-ppc.gz
   qemu-system-ppc: memory backend f0 is used multiple times. Each -numa option must use a different memdev value.

This patch does following:

1. replaces memory_region_allocate_system_memory() with
   memory_region_init_ram() for rom, sram. Then only system memory
   is backed by hugepages when specifying mem-path.

2. for memory banks, allocates all ram with
   one memory_region_allocate_system_memory(), and use
   memory_region_init_alias() to initialize memory banks.

Tested machines: default(g3beige), mac99, taihu, bamboo, ref405ep.

Shreyas B. Prabhu e938ba0c35 ppc: memory: Replace memory_region_init_ram with memory_region_allocate_system_memory
Commit 0b183fc871:"memory: move mem_path handling to
memory_region_allocate_system_memory" split memory_region_init_ram and
memory_region_init_ram_from_file. Also it moved mem-path handling a step
up from memory_region_init_ram to memory_region_allocate_system_memory.

Therefore for any board that uses memory_region_init_ram directly,
-mem-path is not supported.

Fix this by replacing memory_region_init_ram with
memory_region_allocate_system_memory.

Peter Maydell a1f7f97b95 hw/ppc: Avoid shifting left into sign bit
Add U suffix to various places where we were doing "1 << 31",
which is undefined behaviour, and also to other constant
definitions in the same groups, for consistency.

Paolo Bonzini 0d09e41a51 hw: move headers to include/
Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches.
