RZ/G2UL ARM64: Type-1 Part Number: R9A07G043U11GBG#BC0 Type-2 Part Number: R9A07G043U12GBG#BC0 RZ/Five RISCV: 13 x 13 mm Package Part Number: R9A07G043F01GBG#BC0 So to differentiate in ARM schema I am using renesas,r9a07g043f01.

What is the point to keep then r9a07g043 fallback? The two SoCs are not compatible at all, so they must not use the same fallback. Best regards, Krzysztof

"renesas,r9a07g043" is the CPU-less SoC base containing I/O devices. "renesas,r9a07g043f01", "renesas,r9a07g043u11", and "renesas,r9a07g043u12" are SoCs built by integrating one or more RV64 or ARM64 CPU cores and the related interrupt controllers with the CPU-less SoC base.
