Embedded software projects under GPL

[Andreas]

Hi,

I am currently working on an embedded software project.
I like to release it under the GPL if it has left the
early stage of implementation.

Is there a place to put embedded software including the
hardware design?

The embedded software is normaly tightly coupled with
underlaying hardware. Is it possible to put the hardware
design (e.g. schematics) under GPL as well?

Thanks,
Andreas
