Was that referring to CONFIG_SYS_STDIO_DEREGISTER or USB keyboard support? I suspect we should simply enable USB keyboard support everywhere, since most systems don't have built-in keyboards? It's certainly missing from devices like Trimslice that need it. Or would you rather only enable keyboard support on devices without a keyboard, and enable CONFIG_SYS_STDIO_DEREGISTER everywhere?
