[PATCH v4 0/4] RISC-V multi-socket support |

This series adds multi-socket support for RISC-V virt machine and
RISC-V spike machine. The multi-socket support will help us improve
various RISC-V operating systems, firmwares, and bootloader to
support RISC-V NUMA systems.
These patch can be found in riscv_multi_socket_v4 branch at:
https://github.com/avpatel/qemu.git
To try this patches, we will need: Linux multi-PLIC improvements
support which can be found in plic_imp_v2 branch at:
https://github.com/avpatel/linux.git
Changes since v3:
- Use "-numa" QEMU options to populate sockets instead of custom
"multi-socket" sub-option in machine name
Changes since v2:
- Dropped PATCH1 as it is not required any more
- Added "multi-socket" sub-option for Spike and Virt machine
which can be used to enable/disable mult-socket support
Changes since v1:
- Fixed checkpatch errors and warnings
- Added PATCH1 for knowning whether "sockets" sub-option was specified
- Remove SPIKE_CPUS_PER_SOCKET_MIN and SPIKE_CPUS_PER_SOCKET_MAX in PATCH3
- Remove VIRT_CPUS_PER_SOCKET_MIN and VIRT_CPUS_PER_SOCKET_MAX in PATCH5
