5f526d1467 CRIS v10: Setup serial port 2 to avoid accidental TXD pulse on startup.
If serial port 2 is used, select it in R_GEN_CONFIG.
If serial port 2 is used, setup the control registers for the port.
This is done to avoid a pulse on the TXD line during start up,
which could disturb some units.

Also, remove useless CVS id and log.
