 * In an amazing feat of design, the Enhanced Features Register (EFR)
 * shares the address of the Interrupt Identification Register (IIR).
 * Access to EFR is switched on by writing a magic value (0xbf) to the
 * Line Control Register (LCR). Any interrupt firing during this time will
 * see the EFR where it expects the IIR to be, leading to
 * "Unexpected interrupt" messages.
