CONFIG_ENV_ADDR is the start address the flash sector containing the
environment. gd->env_addr is the address in RAM where the environment is
stored.

Please, explain why you want to change gd->env_addr. What do you want to
achieve?

Have a look at then 'env import' command which allows you to import an
alternative environment, e.g. as PREBOOT command.
