TQ offers an optional LVDS Display kit for the STKRZG2x. An LVDS Display can be used by setting the corresponding device tree in the U-Boot environment.
To allow reusage, the support for each display is separated in a separate dtsi fragment.

To bring up the display the U-Boot environment has to be adapted accordingly. 

1. Interrupt boot process in U-boot\\
2. Set U-Boot environment variable fdt_file a specific command has to be used for the differnt types of the TQMaRZG2x:\\  **TQMaRZG2N** <code>setenv fdt_file r8a774b1-tqmarzg2n_b-mbarzg2x-lvds-tm070jvhg33.dtb</code>\\  **TQMaRZG2M-AA** <code>setenv fdt_file r8a774a1-tqmarzg2m_aa-mbarzg2x-lvds-tm070jvhg33.dtb</code>\\  **TQMaRZG2H** <code>setenv fdt_file r8a774e1-tqmarzg2h_c-mbarzg2x-lvds-tm070jvhg33.dtb</code> 
3. Save the envrionment by executing the ''saveenv'' command
