While stack protector support can be used without HWRNG, it will print a warning about the fixed canary to alert to the fact that it requires a random canary to be able to withstand an attacker. Linux HWRNG drivers are surprisingly easy to port to barebox though, so let's import 6 for commonly used platforms. Notably missing is the CAAM for i.MX8M, which will follow separately.
