[PATCH v4 00/11] target/riscv: Support zimop/zcmop/zama16b/zabha

[LIU Zhiwei]

I once used a wrong major opcode for zimop. It should use 0x73 as major opcode.
This was detected after I got a toolchain with zimop support. Before that, I 
tested
this implementation with hardwire code instruction instead of assemble code.

This patch set has been queued to alistair/riscv-to-apply.next, but it is still 
not
merged by the master branch. I think we had better fix it before merging into 
the
master.

v3->v4:
    1. Fix zimop opcode and disassemble

v2->v3:
    1. Add review tags.
    2. Reword the patch 10 in commit log

v1->v2:
    1. Fix the isa orders.
    2. Make zimop/zcmop/zama16b/zabha depend on priviledged 1.13
    3. Add review tags.
