[U-Boot] [RFC PATCH] env: add default env size for CONFIG_ENV_IS_NOWHERE

[Wolfgang Denk]

Dear Bo Shen,

I don;t understand the rationale for this patch.  In which way is the
environment seize for the CONFIG_ENV_IS_NOWHERE case different from
any other cases?  For these, we do not define a default either, so why
should we handle this case differently?

In any cse, the needed environment seize if a pretty board specific
thing, and I think it makes sense to let the user define it.

Best regards,

Wolfgang Denk
