[wpe-webkit] Cog, WPE WebKit and the Linux framebuffer

I have built a Linux image using Yocto (Warrior) for the Atmel SAMA5D2 
reference board that includes Cog, WPE WebKit and wayland built using 
core-image-weston.  The local.conf contains:

IMAGE_INSTALL_append = " wpewebkit cog ca-certificates”

PREFERRED_PROVIDER_virtual/wpebackend = "wpebackend-rdk”
PACKAGECONFIG_pn-wpebackend-rdk = “wayland”

The image works but the startup of wayland and cog seems to take a very 
long time - and longer than is acceptable for this application.  Is it 
possible to change the configuration to get rid of wayland and to run 
directly on top of the Linux framebuffer?  If so, what should the 
configuration look like.

If it is relevant, the SAMA5D2 only has an LCD controller and doesn’t 
have a GPU.  The final application doesn’t require any 3D capabilities 
but if they are required for building WPE WebKit then it will need to be 
software rendering.
