[meta-rockchip][PATCH 1/2] make rockchip kernel tweaks easier to use

[Trevor Woerner]

If linux-yocto is used with this layer, these rockchip tweaks are
available automatically. However, if the user wishes to use their own
linux kernel recipe, these rockchip tweaks are cumbersome since the
MACHINE definition wants to include them. Reorganize how these tweaks
are provided to make them easier to work with when using custom recipes.

Nothing needs to be changed when using linux-yocto. Otherwise simply
provide the following line (or something similar which has the same
effect) in any custom linux kernel recipe:

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

[meta-rockchip][PATCH 2/2] remove-non-rockchip-arch-arm64: remove new arches

[Trevor Woerner]

Over time more architectures are supported by the linux kernel,
architectures unrelated to rockchip. Therefore remove these as well from
the kernel config to help keep its size small.

I don't understand the issue here, specifically the "these rockchip 
tweaks are cumbersome since the MACHINE definition wants to include 
them" part of it. Can you clarify? The change looks zero sum to me so 
I'm not sure what's helping here?

Are you sure this is a good idea? I'm not convinced having config 
fragments spanning multiple kernel versions is a good idea. Not a 
blocker though, and the patch does seem fine to me.

Cheers,
Quentin
