# Handle EULA , if needed. This is a generic method to handle BSPs
# that might (or not) come with a EULA. If a machine has a EULA, we
# assume that its corresponding layers has conf/EULA/$MACHINE file
# with the EULA text, which we will display to the user and request
# for acceptance. If accepted, the variable ACCEPT_EULA_$MACHINE is
# set to 1 in local.conf, which can later be used by the BSP.
# If the env variable EULA_$MACHINE is set it is used by default,
# without prompting the user.
# FIXME: there is a potential issue if the same $MACHINE is set in more than one layer.. but we should assert that earlier

The BSP for $MACHINE depends on packages and firmware which are covered by an
End User License Agreement (EULA). To have the right to use these binaries
in your images, you need to read and accept the following...
The firmware package can contains several types of firmware (depending on BSP):
* bootloaders: the first stage bootloaders are proprietary for this
board, they are included in this firmware package.
* firmware for the power management 'companion' core: on QCOM SoC some
power management features are implemented in a companion core , called
RPM, and not on the main CPU.
* firmware for GPU, WLAN, DSP/GPS and video codecs. These firmware are
used by their respective linux drivers (DRM, wlan, v4l2, .. ) and are
loaded on-demand by the main CPU onto the various cores on the SoC.
