I'm glad to see someone using the Buildroot's EFL packaging :)

I'm maintaining this packaging and I have some patches waiting someone for
review and test: "package/efl: enable libdrm support" [1] and "package/efl: add
Evas GL DRM Engine support" [2].

Since the drm support is not yet merged in Buildroot, I invite you to help me to
improve the EFL packaging by reviewing and testing my patches or provide your
own [3].

Thanks!

Best regards,
Romain
