The "EMGD" driver covers many devices, depending on what version
you're referring too.  The driver that was removed from meta-yocto
supports the SGX-based Atom boards (Tunnel Creek, iirc) and is
unmaintained.  Luckily you're using a modern Atom with Intel HD
graphics, which is supported by the open-source drivers in the
standard kernel and Mesa, so that Valley Island BSP should work just
fine.
