config CPU_EM4_FPUS
arch: arc: kconfig: Define CPU_EM* syms outside Kconfig.defconfig files Define CPU_EM4* and CPU_EM6 in arch/arc/Kconfig to make them always available. That way, the Kconfig.defconfig definitions can skip the type, making them incomplete if the base definition of the symbol disappears. That makes the organization easier to understand and errors easier to spot. The help texts were taken from https://gcc.gnu.org/onlinedocs/gcc/ARC-Options.html. Help texts for invisible symbols can be checked in the menuconfig too if you go into show-all mode, so they're better than adding a comment. Signed-off-by: Ulf Magnusson <Ulf.Magnusson@nordicsemi.no>

kconfig: Use 'default' instead of 'def_bool' in Kconfig.defconfig files Same deal as in commit 4638652214 ("Kconfig: Use 'default' instead of 'def_bool' in Kconfig.defconfig files"), fixing new stuff that got introduced since then. Some symbols, like ALTERA_AVALON_PIO, are only defined in Kconfig.defconfig files, and so need the def_bool. Motivation (from the note at the end of guides/kconfig/index.html#common-shorthands): For a symbol defined in multiple locations (e.g., in a Kconfig.defconfig file in Zephyr), it is best to only give the symbol type for the "base" definition of the symbol, and to use 'default' (instead of 'def_<type>' value) for the remaining definitions. That way, if the base definition of the symbol is removed, the symbol ends up without a type, which generates a warning that points to the other definitions. That makes the extra definitions easier to discover and remove. Signed-off-by: Ulf Magnusson <Ulf.Magnusson@nordicsemi.no>

kconfig: Replace defconfig singe-symbol 'if's with 'depends on' Same deal as in commit eddd98f ("kconfig: Replace some single-symbol 'if's with 'depends on'"), for all symbols defined within defconfig files. See that commit for an explanation. Maybe 'if's were used originally to mirror the 'if's in the main Kconfig files, and then it got copied around by people assuming 'if' must work differently from 'depends on'. It doesn't match in every spot at least. Better to keep it simple and just consistently use 'depends on' when it's a single symbol/choice I think. Helps reinforce that 'if' isn't magic too. Verified by printing all Kconfig menu nodes (symbols, choices, menus, etc.) before and after the change and diffing (should show no difference).
