* Restrict baudrate settings on LWMON to higher speeds

  when watchdog is on

* Update baudrate in bd_info when it gets changed

* Add watchdog trigger points while waiting for serial port
  (so far only 8xx -- needed on LWMON with 100ms watchdog)

* Improve command line tool to access the U-Boot's environment
  (figuration of the utility, using a config file)
