That's indeed a good start! Now if you could build and run eglinfo [1]
on those boards to dump a list of the supported EGL extensions we could
confirm whether they are supposed to work (modulo bugs) with the new DRM
module. In particular, we are looking for the following extensions:

  - EGL_EXT_platform_base
  - EGL_MESA_platform_gbm, or EGL_KHR_platform_gbm
  - EGL_WL_bind_wayland_display
  - EGL_KHR_image_base

I think that is the minimum needed. If support for DMA-BUF is present, and
the driver additionally supports the EGL_EXT_image_dma_buf_import *and*
EGL_EXT_image_dma_buf_import_modifiers, they will be used as well but they
are optional IIUC (Žan will probably jump in and correct me if that's wrong).

Good luck,
