You could as well make ARCH_RENESAS above visible, and defer the actual SoC selection to ARCH_R9A07G043 in drivers/soc/renesas/Kconfig[1]. I don't know what is the policy on RISC-V. ARM64 has a "single-symbol in arch/arm64/Kconfig.platforms"-policy, so we handle SoC selection in drivers/soc/renesas/Kconfig, and that is fine, as it avoids merge conflicts. > + bool "Renesas RZ/Five SoC" > + select ARCH_R9A07G043 > + select ARCH_RENESAS > + select RESET_CONTROLLER > + help > + This enables support for Renesas RZ/Five SoC. > + > endmenu # "SoC selection" [1] https://git.kernel.org/pub/scm/linux/kernel/git/geert/renesas-devel.git/commit/?h=renesas-drivers-for-v6.1&id=ebd0e06f3063cc2e3a689112904b29720579c6d2 Gr{oetje,eeting}s, Geert -- Geert Uytterhoeven -- There's lots of Linux beyond ia32 -- geert@xxxxxxxxxxxxxx In personal conversations with technical people, I call myself a hacker.
