Douglas Anderson c5e7467d92 serial: 8250_early: Support kgdboc_earlycon ... Implement the read() function in the early console driver. With recent kgdb patches this allows you to use kgdb to debug fairly early into the system boot. We only bother implementing this if polling is enabled since kgdb can't be enabled without that.
