ARCH_RENESAS has ARM, ARM64 and RISC based SoCs. Currently it covers ARCH_RCAR_GEN1, ARCH_RCAR_GEN2, ARCH_RCAR_GEN3, ARCH_RCAR_GEN4, ARCH_RMOBILE, ARCH_RZG2L, ARCH_RZN1 Family SOCs and rest of the individual SoCs such as RZ/V2H abnd RZ/g3E. Since most of IP's in RZ/V2H and RZ/G3E are identical we could introduce a new family SoC ARCH_RZG3E_RZV2H to cover both or top level ARCH_RENESAS?? Cheers, Biju
