[for,4.1,v1,0/6] RISC-V: Allow specifying CPU ISA via command line

Message

This patch series adds a generic RISC-V CPU that can be generated at run
time based on the ISA string specified to QEMU via the -cpu argument. This
is supported on the virt and spike boards allowing users to specify the
RISC-V extensions as well as the ISA version.

As part of the conversion we have deprecated the version specifi Spike
machines.

Alistair Francis (6):
  target/riscv: Fall back to generating a RISC-V CPU
  target/riscv: Create settable CPU properties
  riscv: virt: Allow specifying a CPU via commandline
  target/riscvL Remove the unused any CPU
  target/riscv: Remove the generic no MMU CPUs
  riscv: Add a generic spike machine
