If you have a hardware random number generator that is supported by your
kernel then then udev should create the device node automatically as
soon as the relevant kernel module is loaded. If you do not have a
supported HW RNG then it is pointless to generate /dev/hwrng. (The
device nodes for the software entropy mechanism of the kernel are
/dev/random and /dev/urandom.)
