Why is it this way though - it seems to me like you could create a type that just works like the C code

  struct Uart {
    u8 CR2,
    // etc.
  }

Instantiate it as 'static with some macro that defines where it lives in memory:

  #[mcu::loc(0x1002010)] static UART1 = Uart::new();
  #[mcu::loc(0x1003010)] static UART2 = Uart::new();

And then have it bound directly to the memory locations on the MCU at compile time/link time.

Still learning rust, so apologies if this syntax doesn't make sense.
