While the recommended debug method these days is "earlycon", DEBUG_LL is indeed still useful to debug issues before earlycon is initialized. Let's hope you will never encounter such issues on arm64, which doesn't have DEBUG_LL per policy decision... > Signed-off-by: Chris Paterson <chris.paterson2@xxxxxxxxxxx> Reviewed-by: Geert Uytterhoeven <geert+renesas@xxxxxxxxx> > --- a/arch/arm/Kconfig.debug > +++ b/arch/arm/Kconfig.debug > @@ -895,12 +895,13 @@ choice > via SCIF2 on Renesas R-Car H1 (R8A7779). > > config DEBUG_RCAR_GEN2_SCIF0 > - bool "Kernel low-level debugging messages via SCIF0 on R8A7790/R8A7791/R8A7792/R8A7793" > - depends on ARCH_R8A7790 || ARCH_R8A7791 || ARCH_R8A7792 || ARCH_R8A7793 > + bool "Kernel low-level debugging messages via SCIF0 on R8A7743/R8A7790/R8A7791/R8A7792/R8A7793" This line is becoming a bit long, and it'll only become worse in the future. What about "Kernel low-level debugging messages via SCIF0 on R-Car Gen2"? The full list of SoCs is still available in the extended help text. > + depends on ARCH_R8A7743 || ARCH_R8A7790 || ARCH_R8A7791 || \ > + ARCH_R8A7792 || ARCH_R8A7793 > help > Say Y here if you want kernel low-level debugging support > - via SCIF0 on Renesas R-Car H2 (R8A7790), M2-W (R8A7791), V2H > - (R8A7792), or M2-N (R8A7793). > + via SCIF0 on Renesas RZ/G1M (R8A7743), R-Car H2 (R8A7790), > + M2-W (R8A7791), V2H (R8A7792), or M2-N (R8A7793).
