Unable to start unicornd on a rasberry Pi 3B+

$ grep Revision /proc/cpuinfo Revision : a020d3

Patching up fixes this:

$ diff rpihw.c.bak rpihw.c 297a298,308

// // jkane
// Pi 3 Model B+
//
{
    .hwver  = 0xa020d3,
    .type = RPI_HWVER_TYPE_PI2,
    .periph_base = PERIPH_BASE_RPI2,
    .videocore_base = VIDEOCORE_BASE_RPI2,
    .desc = "Pi 3",
},
//

Ah, thanks! Looks like I need to update that submodule to track a newer version of rpi_ws281x.
