target/riscv: Use existing lookup tables for MixColumns
The AES MixColumns and InvMixColumns operations are relatively expensive 4x4 matrix multiplications in GF(2^8), which is why C implementations
target/riscv: Use existing lookup tables for MixColumns
The AES MixColumns and InvMixColumns operations are relatively expensive 4x4 matrix multiplications in GF(2^8), which is why C implementations usually rely on precomputed lookup tables rather than performing the calculations on demand.
Given that we already carry those tables in QEMU, we can just grab the right value in the implementation of the RISC-V AES32 instructions. Note that the tables in question are permuted according to the respective Sbox, so we can omit the Sbox lookup as well in this case.
