+- Console Rx buffer length
+               With CONFIG_SYS_SMC_RXBUFLEN it is possible to define
+               the maximum receive buffer length for the SMC.
+               This option is actual only for 82xx and 8xx possible.
+               If using CONFIG_SYS_SMC_RXBUFLEN also CONFIG_SYS_MAXIDLE
+               must be defined, to setup the maximum idle timeout for
+               the SMC.

+               defining this will force the i2c_read() function in
+               the soft_i2c driver to perform an I2C repeated start
+               between writing the address pointer and reading the
+               data.  If this define is omitted the default behaviour
+               of doing a stop-start sequence will be used.  Most I2C
+               devices can use either method, but some require one or
+               the other.
