I'd like to keep having one Kconfig submenu for each mach-* directory, as most platforms do today. We should really fix the ones that don't currently do it like this.

Is this supposed to include H8/300 and m32r in the future?

Hi Geert, my main aim is to replace ARCH_SHMOBILE and ARCH_SHMOBILE_MULTI with ARCH_RENESAS. I don't believe that would cover H8/300 and m32r, though I am happy to stand corrected. -- To unsubscribe from this list: send the line "unsubscribe linux-sh" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

The purpose of this patch is to start the process of replacing both ARCH_SHMOBILE and ARCH_SHMOBILE_MULTI with ARCH_RENESAS. The motivation being that as time has moved on Renesas has become a name than shmobile for the majority Renesas 32-bit ARM based SoCs. The name is, conveniently, also applicable to (older) Renesas SH based SoCs and (newer) ARM64 based SoCs although this patch only addresses 32-bit ARM. It is envisaged that follow up work may address migrating both SH SoCs and drivers from ARCH_SHMOBILE and ARCH_SHMOBILE_MULTI to ARCH_RENESAS. Proposed support for the r8a7795 ARM64 based SoC already uses ARCH_RENESAS which selects ARCH_SHMOBILE.
