* 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)

# environment sector is assumed present.
fw_env: calculate default number of env sectors The assumed number of environment sectors (always 1) leads to an incorrect top_of_range calculation in fw.env.c when a flash device has an erase block size smaller than the environment data size (number of environment sectors > 1). This change updates the default number of environment sectors to at least cover the size of the environment. Also corrected a false statement about the number of sectors column in fw_env.config.

# Notice, that the "Number of sectors" is not required on NOR and SPI-dataflash.
Add support for dataflash to U-boot environment settings tool. * The sector size for SPI-dataflash (like AT45 flashes) are not always a power-of-2. So, the sector calculations are rewritten such that it works for either power-of-2 as any size sectors. * Make the flash sector size optional in case it is the same value as the environment size.
