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>

# STM32 entropy generator driver configuration
drivers: Rename `random` to `entropy` This should clear up some of the confusion with random number generators and drivers that obtain entropy from the hardware. Also, many hardware number generators have limited bandwidth, so it's natural for their output to be only used for seeding a random number generator.

kconfig: Turn pointless/confusing 'menuconfig's into 'config's Defining a symbol with 'menuconfig' just tells the menuconfig to display any dependent symbols that immediately follow it in a separate menu. 'menuconfig' has no effect on symbol values. Making a symbol that doesn't have any dependent symbols after it a 'menuconfig' should be avoided, because then you end up with an empty menu, which is shown as e.g. [*] Enable foo --- This is how it would be shown if there were children but they all happened to be invisible as well. With a regular 'config', it turns into [*] Enable foo Change all pointless 'menuconfig's to 'config's. See the section on 'menuconfig' on the Kconfig - Tips and Best Practices page as well.

select USE_STM32_LL_RNG
drivers/entropy: stm32: Convert driver to dt based configuration Convert stm32 entropy driver to configuration based on device tree. Select HAS_DTS_ENTROPY symbols and configure CONFIG_ENTROPY_NAME in fixup files. Since rng node is not enabled (or available) on all boards, it could happen that symbol ENTROPY_STM32_RNG is not enabled and hence ENTROPY_HAS_DRIVER not selected which ends up with a symbol ENTROPY_NAME defined throufg Kconfig selection. Thus, in fixup file, CONFIG_ENTROPY_NAME is defined only if not already defined. Additionally, update boards that used to configure entropy by default. On these boards, enable rng device in device tree and remove Kconfig related configuration (which should not be part of default configuration). Signed-off-by: Erwan Gouriou <erwan.gouriou@linaro.org>
