kconfig: Clean up header comments and make them consistent Use this short header style in all Kconfig files: # <description> # <copyright> # <license> ... Also change all <description>s from # Kconfig[.extension] - Foo-related options to just # Foo-related options It's clear enough that it's about Kconfig. The <description> cleanup was done with this command, along with some manual cleanup (big letter at the start, etc.) git ls-files '*Kconfig*' | \ xargs sed -i -E '1 s/#\s*Kconfig[\w.-]*\s*-\s*/# /' Signed-off-by: Ulf Magnusson <Ulf.Magnusson@nordicsemi.no>

boards: stm32h474i_disco: Fix m4 core sys clock System clock for m4 core was set to same clock as m7 core. This is wrong as m4 its value is actually based on clock frequency value after D1CPRE (sys_d1cpre_ck) divided per HPRE value, 200MHz in current case. This also matches the max clock speed for the m4 core (200MHz) Signed-off-by: Erwan Gouriou <erwan.gouriou@linaro.org>

config STM32H7_DUAL_CORE
kconfig: Remove symbol types from Kconfig.defconfig files Same deal as in commit 7fdb5257547 ("kconfig: Use 'default' instead of 'def_bool' in Kconfig.defconfig files"), but I hacked Kconfiglib to also find cases where the type is given separately as e.g. config FOO int default 3 Motivation (from a note in https://docs.zephyrproject.org/latest/guides/kconfig/index.html): 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. It's also nice if 'def_bool' and the like turn into a semi-reliable flag that the symbol is only defined in Kconfig.defconfig files. That might be a sign that things could be cleaned up. Will do a separate pass later to remove some symbols only defined in Kconfig.defconfig files.

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).
