I suggest you go with your own distro then, as you can leverage the DISTRO_FEATURES in it yourself. You can either take any of 'fsl-' prefixed distros over 'poky' if you need some NXP proprietary components (e.g. VPU, GPU, etc), or take any of 'fslc-' prefixed ones if you want to stay with mainline. Please note - I do not say that 'poky' would not work here! :) It is just a reference distro from Yocto Project, which targets qemu on the first place, but also works well for real HW.
This is the way we build our distro (derived from 'fsl-wayland'), and so far it has proven to be working quite well. I also do sanity build and run the 'fsl-wayland' off the master on imx8mmevk to make sure there are no regressions.
When I did NXP released builds I would use fsl-wayland distro but if memory serves me right a core-image-minimal would not boot. Only core-image-base images did and they were quite large.
I do need to create my own distro but kind of would like to start from core-image-minimal and build up rather than take something like fsl-wayland and try to figure out what I don't need. Being new to NXP family this approach "feels" more logical.
Is poky what's causing my pain?
You can see what distro features you have included when you do 'bitbake -e' and search for DISTRO_FEATURES. If you have (and according to what you say - you do :) ) some pieces you do not need - you can always either not include them in your custom distro, or use DISTRO_FEATURES_remove = "<unneeded list>".
I've been doing TI based builds forever and recently switched over to NXP based products so still learning the lay of the land. I finally discovered I don't think I want to be building based off NXP releases from codeaurora and that Freescale is the better base for our products but not 100% clear what distro's are available and which ones I should focus on.
Those distros are located in a meta-freescale-distro layer, you can peek there to see what's available.
