Does anybody know if there's an easy way to get a hardware Rng for TLS? I tried this:

        let rng_peripherals = Peripherals::take();

        let mut rng_system = rng_peripherals.SYSTEM.split();
        let rng_clocks = ClockControl::boot_defaults(rng_system.clock_control).freeze();
        
        let mut rng_rtc = Rtc::new(rng_peripherals.LPWR);
        let rng_timer_group0 = TimerGroup::new(
                rng_peripherals.TIMG0,
                &rng_clocks,
        );
        let mut wdt0 = rng_timer_group0.wdt;
        let rng_timer_group1 = TimerGroup::new(
                rng_peripherals.TIMG1,
                &rng_clocks,
        );
        let mut wdt1 = rng_timer_group1.wdt;
        
        rng_rtc.swd.disable();
        rng_rtc.rwdt.disable();
        wdt0.disable();
        wdt1.disable();

        let mut rng = Rng::new(rng_peripherals.RNG);

And am implementing it here:

        let tls_context = TlsContext::new(&tls_config, &mut rng);

But the compiler is telling me that these trait bounds are not satisfied:

        CryptoRng + RngCore 

I tried using OsRng from randcore and the getrandom feature flag, but the compiler complained that my target isn't supported.
