----------- Device parameters --------------
-
-Devices have several parameters. In case of a network device this may be the
-ip address, networking mask or similar and users need access to these
-parameters. in U-Boot this is solved with device paramters. Device parameters
-are always strings, although there are functions to interpret them as
-something else. hush users can access parameters as a local variable which
-have a dot (.) in them. So setting the ip address of the first ethernet
-device is a matter of typing 'eth0.ip=192.168.0.7' on the console and can
-then be read back with 'echo $eth0.ip'. The devinfo command shows a summary
-about all devices currently present. If called with a device id as parameter
-it shows the parameters available for a device.

-struct param_d {
-	char* (*get)(struct device_d *, struct param_d *param);
-	int (*set)(struct device_d *, struct param_d *param, const char *val);
-	ulong flags;
-	char *name;
-	struct param_d *next;
-	char *value;
-};
-
-int dev_add_param(struct device_d *dev, struct param_d *par);
-
-This function adds a new parameter to a device. At least the name field in
-the new parameter struct has to be initialized. The 'get' and 'set' fields
-can be set to NULL in which case the framework handles them. It is also
-allowed to implement only one of the get/set functions. Care must be taken
-with the initial value of the parameter. If the framework handles the set
-function it will try to free the value of the parameter. If this is a
-static array bad things will happen. A parameter can have the flag
-PARAM_FLAG_RO which means that the parameter is readonly. It is perfectly ok
-then to point the value to a static array.
-
-const char *dev_get_param(struct device_d *dev, const char *name);
-
-This function returns a pointer to the value of the parameter specified
-with dev and name.
-If the framework handles the get/set functions the parameter value strings
-are alloceted with malloc and freed with free when another value is set for
-this parameter. Drivers implementing set/get themselves are allowed to
-return values in static arrays. This means that the pointers returned from
-dev_get_param() are only valid until the next call to dev_get_param. If this
-is not long enough strdup() or similar must be used.
-
-int dev_set_param(struct device_d *dev, const char *name, const char *val);
-
-Set the value of a parameter.
