[PATCH v2 0/3] RISC-V virt MHP support

[Björn Töpel]

From: Björn Töpel <bjorn@rivosinc.com>

The RISC-V "virt" machine is currently missing memory hotplugging
support (MHP). This series adds the missing virtio-md, and PC-DIMM
support.

I've include both the ACPI MHP/GED/PC-DIMM, and virtio-md in the same
series. The two patches (virtio-md) are probably less controversial,
and can be pulled separately from the last patch.

The first patch includes MHP that works with DT. The second patch is
basic device memory ACPI SRAT plumbing.

The third patch includes ACPI GED, and ACPI MHP/PC-DIMM support.


Changelog

v1->v2:
 * Cap the maximum number of supported ram slots (Daniel)
 * Split the ACPI parts out from virtio-md patch (Daniel)
 * Allow for max 1G PC-DIMM alignment per ram slot (Daniel)
 * Add missing defined(__riscv__) for virtio-mem code
 * Include PC-DIMM MHP supportin the series
 * Misc code structure changes

Cheers,
Björn
