/*
 * Basic register map implementation in C++. Makes reading/writing registers
 * safer, should be just as efficient as doing things the old fashioned way.
 * The setup is a little ugly, but such is life. It was never going to be pretty
 * anyway.
 *
 * Requires C++20, though that could be changed with a little SFINAE trickery.
 *
 * Example code uses GPIO peripherals on an AM3358.
