[PATCH v3 00/10] ARM virt: Add NVDIMM support

[Shameer Kolothum <shameerali.kolothum.thodi@huawei.com>]

This series adds NVDIMM support to arm/virt platform.
The series reuses some of the patches posted by Eric
in his earlier attempt here[1].

This also include few fixes to qemu in general which were
discovered while adding nvdimm support to arm/virt.

Patch #2 addresses the issue[2] that, during migration, the 
source and destination might end up with an inconsistency
in acpi table memory region sizes.

Patch #3 is to fix the qemu_ram_resize() callback issue[2].

Patch #4 is another fix to the nvdimm aml issue discussed
here[3].

I have done a basic sanity testing of NVDIMM devices
with Guest booting with ACPI. Further testing is always
welcome.

Please let me know your feedback.

Thanks,
Shameer

   David H.
 - The fix for qemu_ram_resize() callback was modified to
   the one in patch #3. Again thanks to David H.
 - Addressed comments from MST and Eric on tests added.
 - Addressed comments from Igor/MST on Integer size in patch #4
 - Added Eric's R-by to patch #7.

v1 --> v2
 -Reworked patch #1 and now fix is inside qemu_ram_resize().
 -Added patch #2 to fix the nvdim aml issue.
 -Dropped support to DT cold plug.
 -Updated test_acpi_virt_tcg_memhp() with pc-dimm and nvdimms(patch #7)
