Hello Charlie,
Thanks for your patch. A couple of comments/questions below. Most are
trivial stuff, but one question requires some cog knowledge that I
don't have.

We typically don't use "depends on" for such dependencies, but a
"select". That will require however that you replicate the "depends on"
dependencies of BR2_PACKAGE_LIBDRM here.
Also, your .mk file adds a dependency on libinput, so you need a
"select BR2_PACKAGE_LIBINPUT" here.

So, now that a second "platform" is supported, do we want the "fdo"
platform to be always unconditionally enabled ? What is the "fdo"
platform compared to the "drm" platform ?

Those lines should not be indented with one tab.
