Help text

Broadcom BCM2835 and similar SoCs have a VPU called VideoCore. This config enables the VCHIQ driver, which implements a messaging interface between the kernel and the firmware running on VideoCore. Other drivers use this interface to communicate to the VPU. More specifically, the VCHIQ driver is used by audio/video and camera drivers as well as for implementing MMAL API, which is in turn used by several multimedia services on the BCM2835 family of SoCs. Defaults to Y when the Broadcom Videocore services are included in the build, N otherwise.
