Description

Apertis currently supports Renesas R-Car M3 Starter Kit Pro (M3SK/m3ulcb) and Renesas R-Car H3 Starter Kit Premier (H3SK/h3ulcb), however, u-boot is not able to detect the right variant and sets renesas/r8a7795-h3ulcb.dtb as default dtb causing m3 variant not to boot with default environment.
