Thanks for this work and sorry for the late review. One thing to look out as a follow-up is the 'max' CPU. It has the same name in both 32 and 64 bits so it'll result in a conflict with the 'max' CPU for rv64. One easy way out is to add a new 'max32' bit CPU for riscv32, which would be an alias for the 'max' CPU, then adding 'max32' support in rv64.

I think it is good. One question is if we should also add any32 cpu for rv64, which has the similar conflict of 'max' CPU.

From: 甲一 <lzw194868@alibaba-inc.com> This patch set aims to expose 32-bit RISC-V cpu to RV64 QEMU. Thus qemu-system-riscv64 can directly boot a RV32 Linux.
