MACHINEOVERRIDES .= ":pitft" Using MACHINE_FEATURES will be more
appropriate term. Effects are same. Indeed. I support MACHINE_FEATURE
usage here. I agree that the term MACHINE_FEATURES is better. However
since MACHINE_FEATURES isn't included in the OVERRIDES variable I will
not be able to use the task pre/appends that was the reason I used
MACHINEOVERRIDES in the first place. The reason I want to use overrides
in this case is since I think it makes the code easier to read and
understand for the user (in this particular case at least). I can of
course change to just using variables (like in many other optional
features in meta-raspberrypi) or change to MACHINE_FEATURES. But I'm not
sure how I can solve for example the below part in a effective and nice
way:

MACHINE_FEATURES in python or shell.

Yes, I'm aware of that I can use
it that way. It was just my personal opinion that the code looks better
with overrides in this particular case. On the other hand I can agree
that the end-user will be more comfortable with using MACHINE_FEATURES
instead of MACHINEOVERRIDES. Also since both you and Andrei push for
MACHINE_FEATURES I will bend for your will =) 

Start using
MACHINE_FEATURES from local.conf when using meta-raspberrypi will
require a minor change i rpi-base.inc as well, since it otherwise will
override MACHINE_FEATURES added in local.conf. I will send up a fix for
that in v2 of this series as well. 

Thanks for your feedback.
