This bit also references the commented out/deleted code. IMO it would
make sense to rephrase this entire comment block such that it explains
what the original intention of this entire function was and the problem
associated with it. How about something like:

/*
 * For complete POSIX compatibility, we should be purging the read FIFO
 * in the UART here.
 *
 * However, clearing the read FIFO (UART_FCR_CLEAR_RCVR) also
 * incorrectly flushes write data as well as just basically trashing the
 * FIFO.
 *
 * Presumably, this is a bug in this UART.
