[PATCH v2 0/7] ARM virt: Add NVDIMM support

[Shameer Kolothum]

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].

Patch #1 is a fix to the Guest reboot issue on NVDIMM
hot add case described here[2] and patch #2 is another
fix to the nvdimm aml issue discussed here[3].

I have done a basic sanity testing of NVDIMM deviecs
with Guest booting with both ACPI and DT. Further testing
is always welcome.

Please let me know your feedback.

Thanks,
Shameer
