In your board-specific configs header file (include/configs/your-header.h) you 
will have a section something like this:


/*
 * Environment Configuration
 */

#define CONFIG_ENV_OVERWRITE

#define CONFIG_BAUDRATE 115200

#define CONFIG_LOADADDR 800000  /* default location for tftp and bootm */

#define CONFIG_BOOTDELAY 3      /* -1 disables auto-boot */
#undef CONFIG_BOOTARGS          /* the boot command will set bootargs */

#define CONFIG_EXTRA_ENV_SETTINGS                                       \
   "autoload=n\0"                                                               
\
   "consoledev=ttyS0\0"                                                 \
   ""
#define CONFIG_BOOTCOMMAND "run ramboot"



Some of the commands are set with CONFIG_XXX macros (e.g. CONFIG_BOOTCOMMAND), 
the rest go in CONFIG_EXTRA_ENV_SETTINGS.

The uboot parameters are stored in flash on your target.
You want printenv and savenv:
