+## Enable Raspberrypi Camera V2
+
+RaspberryPi does not have the unicam device ( RaspberryPi Camera ) enabled by default.
+Because this unicam device ( bcm2835-unicam ) as of now is used by libcamera opensource.
+So we have to explicitly set in local.conf.
+
+    RASPBERRYPI_CAMERA_V2 = "1"
+
+This will add the device tree overlays imx219 ( RaspberryPi Camera sensor V2 driver ) to config.txt.
+Also, this will enable adding Contiguous Memory Allocation value in the cmdline.txt.
