Gregory Nutt c83da3c48f Remove minnsh configurations and support logic: up_getc() and lowinstream. ... This was an interesting exercise to see just how small you could get NuttX, but otherwise it was not useful: (1) the NSH code violated the OS interface layer by callup up_getc and up_putc directly, and (2) while waiting for character input, NSH would call up_getc() which would hog all of the CPU. NOt a reasonably solution other than as a proof of concept.		2016-12-13 18:01:23 -06:00
