In the RISC-V world, CPUs are often designed by companies like SiFive, T-Head and Andes.
Use the /proc/cpuinfo 'uarch' values to get the CPU designer and CPU model.
These designs are then licensed to SoC manufacturers who add I/O and GPU features.
For example Allwinner (D1) and StarFive (JH7110), and Sophgo (SG2000)
