I'm not sure what exactly you mean here.

Stdin, stdout, and stderr are first of all terms that relate to the
standard C library, more precisely to it's implementation of standard
I/O streams.  This has obviously little to do with U-Boot itself.

In U-Boot's terminology we use these names as references to I/O
channels which can be assigned to different devices. Such devices may
be serial or network ports (for input and output), keyboards (input
only), LCD screens or other video adapters (output only).

"lcd environment" or "non-lcd environment" is not really related at
all to these terms.

And never, never ever send HTML. Always send plain text only.

Thanks.
