To enable the cedartrail layer that supports Power VR graphics,
add the cedartrail MACHINE to local.conf:

Power VR Graphics user-space driver binaries are covered by a
"Intel Free Distribution Binary License". The build of this driver
can be enabled by adding the following line to the local.conf file:
LICENSE_FLAGS_WHITELIST += "license_cdv-pvr-driver_1.0"
To enable the layer that does not support Power VR graphics
add the following to the local.conf file:
MACHINE ?= "cedartrail-nopvr"
You should then be able to build a cedartrail image as such:
$ source oe-init-build-env
$ bitbake core-image-sato
The above image will not give you the webkit feature and will not
have the Audio and Video media samples in the image.
If you want the webkit feature and Audio , Video media samples built
into the image by default, You should build the custom image by
doing the following:
$ source oe-init-build-env
$ bitbake core-image-cdv-media
At the end of a successful build, you should have a live image that
you can boot from a USB flash drive (see instructions on how to do
that below, in the section 'Booting the images from /binary').

Miscellaneous Notes
====================
Video and Music Samples
-----------------------
This BSP includes recipes to download Ogg format video and
music files that can be played-back with the Video and music players
included in the sato images. The sample files are installed in
/home/Music and /home/Videos directories.
Adding Glxgears to image
-------------------------
Glxgears can be added to the generated image by adding "tools-testapps"
option to the extra image features variable in the default local.conf
before building the BSP.
e.g. to add Glxgears, locate the following line in local.conf
EXTRA_IMAGE_FEATURES = "debug-tweaks"
and change above line to..
EXTRA_IMAGE_FEATURES = "debug-tweaks tools-testapps"
