    Serial: p1011: new vendor init options · 910f1ae3
    John Rigby authored and Wolfgang Denk's avatar Wolfgang Denk committed
    
    
    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
