* tty/serial: add arm/arm64 semihosting earlyconRob Herring2014-04-251-0/+61
Add earlycon support for the arm/arm64 semihosting debug serial interface. This allows enabling a debug console when early_params are processed. This is based on the arm64 earlyprintk smh support and is intended to replace it.
