2 Changes since U-Boot 0.3.1:
3 ======================================================================
5 * Get (mostly) rid of CFG_MONITOR_LEN definition; compute real length
6 instead CFG_MONITOR_LEN is now only used to determine _at_compile_
7 _time_ (!) if the environment is embedded within the U-Boot image,
8 or in a separate flash sector.
10 * Cleanup CFG_DER #defines in config files (wd maintained only)

20 execute "cmd2", even if "cmd1" fails. Note that this is different
21 to "run var1 var2" where the contents of "var2" will NOT be
22 executed when a command in "var1" fails.
