-Command Line Parsing:
-=====================
-
-There are two different command line parsers available with U-Boot:
-the old "simple" one, and the much more powerful "hush" shell:
-
-Old, simple command line parser:
---------------------------------
-
-- supports environment variables (through setenv / saveenv commands)
-- several commands on one line, separated by ';'
-- variable substitution using "... ${name} ..." syntax
-- special characters ('$', ';') can be escaped by prefixing with '\',
-  for example:
-	setenv bootcmd bootm \${address}
-- You can also escape text by enclosing in single apostrophes, for example:
-	setenv addip 'setenv bootargs $bootargs ip=$ipaddr:$serverip:$gatewayip:$netmask:$hostname::off'
-
-Hush shell:
------------
-
-- similar to Bourne shell, with control structures like
-  if...then...else...fi, for...do...done; while...do...done,
-  until...do...done, ...
-- supports environment ("global") variables (through setenv / saveenv
-  commands) and local shell variables (through standard shell syntax
-  "name=value"); only environment variables can be used with "run"
-  command
-
-General rules:
---------------
-
-(1) If a command line (or an environment variable executed by a "run"
-    command) contains several commands separated by semicolon, and
-    one of these commands fails, then the remaining commands will be
-    executed anyway.
-
-(2) If you execute several variables with one call to run (i. e.
-    calling run with a list of variables as arguments), any failing
-    command will cause "run" to terminate, i. e. the remaining
-    variables are not executed.
