We still need to be careful about not changing the Kconfig option name for something like this as it will cause the custom .config files to fail unless the default is y. But yeah I agree, it would be nice to have some multiarch sane default selects, then also do the platform specific selects as needed. Naturally this needs to be kept down to minimum ideally limited to silent options. So we could have ARCH_MULTIPLATFORM_TYPICAL, then have the old ARCH_OMAP2PLUS_TYPICAL select that one. That should keep things behaving just fine if the old .config had ARCH_OMAP2PLUS_TYPICAL. > For I2C_OMAP, MENELAUS and TWL4030, we could just add a > 'default ARCH_OMAP3 || ARCH_OMAP4' or whatever is appropriate for > each of them.

TWL4030 is omap2430 to omap3, I don't think we currently have any omap3 based ones not using twl4030.. But there certainly are tons of usable devices with the Motorola CPCAP PMIC instead. Then REGULATOR_FIXED_VOLTAGE we can have platform select like Mark seems to prefer. HIGHMEM too should be platform specific. The original reason for ARCH_OMAP2PLUS_TYPICAL was that if omap2plus is selected with that you actually get a bootable system.
