This is better, as if anyone allocated memory before, we will not use
that memory, and still use uninitalized memory..

This is better than using RAM, as it keeps the state between power
cycles...

symbols defined by the linker script are all treated as addresses, so
we need to get the address, and cast it to an integer for the length
case..

The return value must be used, but as we init early on, we don't need
to check it, so just hide the error w/ an inline function..
