/*
* @brief IO redirection support
*
* This file adds re-direction support to the library for various
* projects. It can be configured in one of 3 ways - no redirection,
* redirection via a UART, or redirection via semihosting. If DEBUG
* is not defined, all printf statements will do nothing with the
* output being throw away. If DEBUG is defined, then the choice of
* output is selected by the DEBUG_SEMIHOSTING define. If the
* DEBUG_SEMIHOSTING is not defined, then output is redirected via
* the UART. If DEBUG_SEMIHOSTING is defined, then output will be
* attempted to be redirected via semihosting. If the UART method
* is used, then the Board_UARTPutChar and Board_UARTGetChar
* functions must be defined to be used by this driver and the UART
* must already be initialized to the correct settings.
