If the machines defined in this layer are used, they will want to pull
in the kmeta data that is also provided in this layer when configuring
the Linux kernel. This all works automatically if linux-yocto or
linux-yocto-dev are used. But it causes build failures if a kernel
recipe is used or defined that is not one of these two.

Putting this layer-specific metadata into an *.inc file (then
referencing it in the kernel bbappends provided in this layer) makes
that metadata available to any other kernel recipe through the "require"
or "include" mechanism. Any other kernel recipe that is created can pull
in this metadata using either of these lines in the kernel recipe:

	require recipes-kernel/linux/linux-rockchip.inc
	include recipes-kernel/linux/linux-rockchip.inc

This layer can not guess or assume what other kernel recipes might be
used with its machine definitions, and providing random, potentially
dangling, bbappends is not a solution either. Therefore splitting this
layer's information into an *.inc file makes it available to recipes
outside this layer.

changes from v1:
- updated the commit message after discussions with Quentin
- hopefully this version provides a clearer explanation and reasoning
  for the change
