=======================================
This is the general hardware specific BSP overlay for the RaspberryPi device. This is the general hardware specific BSP overlay for the RaspberryPi device.
It should be used with openembedded-core (not old-style org.openembedded.dev).

Build scripts patched to support making a firmware image for the RaspberryPi
with Angstrom can be found at:

When not depending on meta-openembedded and not using systemd, you may need to
mask few recipes requiring systemd or other recipes not included in your
distribution of choice.
You can achieve this by adding something like the following to local.conf:
BBMASK = "meta-raspberrypi/recipes-multimedia/libav|\
meta-raspberrypi/recipes-core/systemd"
You can adjust the BBMASK for any .bbappends that your distribution does not
contain recipes for.
