[PATCH v2 0/9] RISC-V: Steps towards running 32-bit guests on

[Alistair Francis <alistair.francis@wdc.com>]

This is another step towards running 32-bit CPU code on the 64-bit
softmmu builds for RISC-V.

I have tested this and am able to run some 32-bit code, but eventually
hit some issue.  This series doesn't allow users to use 32-bit CPUs with
64-bit softmmu builds as it doesn't work yet. This series instead just
gets us a little closer to being able to and removes more hardcoded
macros so hopefully others also stop using them for new code.

v2:
 - Update the decode tree setup
 - Address other review comments

Alistair Francis (9):
  target/riscv: Remove the hardcoded RVXLEN macro
  target/riscv: Remove the hardcoded SSTATUS_SD macro
  target/riscv: Remove the hardcoded HGATP_MODE macro
  target/riscv: Remove the hardcoded MSTATUS_SD macro
  target/riscv: Remove the hardcoded SATP_MODE macro
  target/riscv: Remove the unused HSTATUS_WPRI macro
  target/riscv: Remove an unused CASE_OP_32_64 macro
  target/riscv: Consolidate RV32/64 32-bit instructions
  target/riscv: Consolidate RV32/64 16-bit instructions
