+ * Command line user interface to firmware (=U-Boot) environment.
+ *
+ * Implements:
+ * fw_printenv [[ -n name ] | [ name ... ]]
+ * - prints the value of a single environment variable
+ * "name", the ``name=value'' pairs of one or more
+ * environment variables "name", or the whole
+ * environment if no names are specified.
+ * fw_setenv name [ value ... ]
+ * - If a name without any values is given, the variable
+ * with this name is deleted from the environment;
+ * otherwise, all "value" arguments are concatenated,
+ * separated by single blank characters, and the
+ * resulting string is assigned to the environment
+ * variable "name"
