[PATCH v3 0/7] support subsets of scalar crypto extension |

This patchset implements RISC-V K-extension v1.0.0.rc6 version instructions.
Partial instructions are reused from B-extension.
Specification:
https://github.com/riscv/riscv-crypto
The port is available here:
https://github.com/plctlab/plct-qemu/tree/plct-k-upstream-v3
To test rvk implementation, specify cpu argument with 'x-zks=true,x-zkn=true'
or
"x-zbkb=true,x-zbkc=true,x-zbkx=true,x-zknd=true,x-zkne=true,x-zknh=true,x-zksed=true,x-zksh=true,x-zkr=true"
to enable K-extension support. This implementation can pass the ACT tests
for K with our extended act support for qemu (available at
https://github.com/plctlab/plct-qemu/tree/plct-k-upstream-v3-with-act)
v3:
* add extension check for SEED csr access
v2:
* optimize implementation for brev8, xperm, zip, unzip
* use aes related sbox array from crypto/aes.h
* move sm4_sbox to crypto/sm4.c, and share it with target/arm
liweiwei (7):
target/riscv: rvk: add cfg properties for zbk* and zk*
target/riscv: rvk: add implementation of instructions for Zbk*
crypto include/crypto target/arm: move sm4_sbox to crypto
target/riscv: rvk: add implementation of instructions for Zk*
target/riscv: rvk: add CSR support for Zkr
disas/riscv.c: rvk: add disas support for Zbk* and Zk* instructions
target/riscv: rvk: expose zbk* and zk* properties
