* 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)
