# Freescale Kernel Vivante Kernel Driver handler
#
# Enable the kernel to provide or not the Vivante kernel driver and
# dynamically set the proper providers per machine.
#
# The following options are supported:
#
# MACHINE_HAS_VIVANTE_KERNEL_DRIVER_SUPPORT
#
# Machine does or does not have support for the Vivante kernel
# driver, options are:
#
# 0 - machine does not have Vivante GPU driver support
# 1 - machine has Vivante GPU driver support
#
# MACHINE_USES_VIVANTE_KERNEL_DRIVER_MODULE
#
# Machine uses the Vivante kernel driver as module, options are:
#
# 0 - enable the builtin kernel driver module
# 1 - enable the external kernel module
