[U-Boot] API_env_enum behaviour with SPI serial flash

Hi,

I have a board with a SPI serial flash which runs u-boot 2011.12 and when I make a call to API_env_enum() it only enumerates through the list of environment variables present in the default_environment table and does not enumerate any user configured variables. Is this behaviour by design or have I missed anything.

Any help or pointer to codes will be much appreciated.

Thanks, ritu
