Two new options:
CONFIG_PL011_SERIAL_RLCR
Some vendor versions of PL011 serial ports (e.g. ST-Ericsson U8500) have separate receive and transmit line control registers. Set this variable to initialize the extra register.
CONFIG_PL011_SERIAL_FLUSH_ON_INIT
On some platforms (e.g. U8500) U-Boot is loaded by a second stage boot loader that has already initialized the UART. Define this variable to flush the UART at init time. empty fifo on init
