This patches supported RISC-V migration based on tcg accel. And we have
verified related migration features such as snapshot and live migration.

A few weeks ago, we submitted RFC patches about supporting RISC-V migration
based on kvm accel: https://www.spinics.net/lists/kvm/msg223605.html.
And we found that tcg accelerated migration can be supported with a few
changes. Most of the devices have already implemented the migration
interface, so, to achieve the tcg accelerated migration, we just need to
add vmstate of both cpu and sifive_plic.

Yifei Jiang (5):
  target/riscv: Add basic vmstate description of CPU
  target/riscv: Add PMP state description
  target/riscv: Add H extention state description
  target/riscv: Add V extention state description
  target/riscv: Add sifive_plic vmstate
