I have already explained my doubts regarding the abuse of
EXTRA_ENV_SETTINGS. The setup that should be minimal and general for
most of uses is then customized for a specific scope, that conflict with
other goals. You are changing the filesystem on the card: I cannot
estimate how this can be useful for everyone (maybe yes, maybe not).
I hope that Simon's patches to split the default environment from the
configuration file will find soon a way to mainline. Check in the ML for
env: Add support for environment files
Then it will be possible to define an own text file containing the
environment outside of the configuration file. And adding a new default
environment will mean only to specify the env file in boards.cfg.

We had already some discussion on the mailing list about the meaning and
the usefulness of the U-Boot prompt. I will apply a patch for all
Freescale boards that remove a custom prompt, letting the default. Which
is the improvement to have a custom prompt ?
Maybe you are the second one asking for the feature:
http://u-boot.10912.n7.nabble.com/Changing-CONFIG-SYS-PROMPT-on-the-fly-td166105.html
As suggested by Simon (take a look at the whole thread), it is then
better to set the prompt from an environment variable. Feel free to
submit a patch for it.
Best regards,
Stefano Babic
