[PATCH v1 00/16] RISC-V: Start to remove xlen preprocess

[Alistair Francis]

The RISC-V QEMU port currently has lot of preprocessor directives that
check if we are targetting a 32-bit or 64-bit CPU. This means that the
64-bit RISC-V target can not run 32-bit CPUs. This is different to most
other QEMU architectures and doesn't allow us to mix xlens (such as when
running Hypervisors with different xlen guests).

This series is a step toward removing some of those to allow us to use
32-bit CPUs on 64-bit RISC-V targets.

Alistair Francis (16):
  target/riscv: Add a TYPE_RISCV_CPU_BASE CPU
  riscv: spike: Remove target macro conditionals
  riscv: virt: Remove target macro conditionals
  hw/riscv: boot: Remove compile time XLEN checks
  hw/riscv: virt: Remove compile time XLEN checks
  hw/riscv: spike: Remove compile time XLEN checks
  hw/riscv: sifive_u: Remove compile time XLEN checks
  target/riscv: fpu_helper: Match function defs in HELPER macros
  target/riscv: Add a riscv_cpu_is_32bit() helper function
  target/riscv: Specify the XLEN for CPUs
  target/riscv: cpu: Remove compile time XLEN checks
  target/riscv: cpu_helper: Remove compile time XLEN checks
  target/riscv: csr: Remove compile time XLEN checks
  target/riscv: cpu: Set XLEN independently from target
  target/riscv: Convert the get/set_field() to support 64-bit values
  target/riscv: Consolidate *statush registers
