    dev: introduce uart-sw · fd3f8864
    Alessandro Rubini authored
    This introduces dev/uart-sw as an alternative to dev/uart . The
    software-only thing is a pair of circular buffers that can be driven
    by tools/wrpc-uart-sw .
    The software uart can be enabled by Kconfig (and is disabled by
    default).  The code size is the same as the uart, but it "wastes" 306
    bytes of data space.
