Ah, now I see what you mean.  But this is awkward.  Why do we need
both CONFIG_ENV_VAR_<foo> and <foo> ?  Also note that these BOARD_*
names are kind of polluting the name space.  I don't like that.

Just use a single variable with an appropriate value for each of
these settings.  And don't pass these on the command line (which is
already unreadable enough), but add it to the auto-generated config
file.

And make the whole feature user selectable - I think it makes no sense
if you have to individually enable all the 5 settings.


Hm... thinking about this, I also don't like the "board_*" prefix.
What you actually have are names, i. e. it should probably read
"soc_name" instead of "board_soc", etc.

Best regards,

Wolfgang Denk
