[PATCH 0/6] Support RISC-V IOPMP

[Ethan Chen]

This series implements IOPMP specification v1.0.0-draft4 rapid-k model:
https://github.com/riscv-non-isa/iopmp-spec/blob/main/riscv_iopmp_specification.pdf

When IOPMP is enabled, a DMA device ATCDMAC300 is added to RISC-V virt platform.
This DMA devce is connected to the IOPMP and has the functionalities required
by IOPMP, including:
- Support specify source-id (SID)
- Support asynchronous I/O to handle stall transcations

Ethan Chen (6):
  exec/memory: Introduce the translate_size function within the IOMMU
    class
  system/physmem: IOMMU: Invoke the translate_size function if it is
    implemented
  exec/memattrs: Add iopmp source id to MemTxAttrs
  Add RISC-V IOPMP support
  hw/dma: Add Andes ATCDMAC300 support
  hw/riscv/virt: Add IOPMP support
