    8xx serial, smc: add configurable SMC Rx buffer len · 2b3f12c2

    This patch adds the configuration option CONFIG_SYS_SMC_RXBUFLEN.
    With this option it is possible to allow the receive
    buffer for the SMC on 8xx to be greater then 1. In case
    CONFIG_SYS_SMC_RXBUFLEN == 1 this driver works as the
    old version.
    
    When defining CONFIG_SYS_SMC_RXBUFLEN also
    CONFIG_SYS_MAXIDLE must be defined to setup the maximum
    idle timeout for the SMC.
