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>

# esp32 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: drivers: entropy: Remove duplicated ENTROPY_GENERATOR deps. Also remove some duplicated dependencies for the related symbol ENTROPY_NRF5_RNG. The redundant ENTROPY_GENERATOR deps. are in files sourced within a if ENTROPY_GENERATOR ... endif block in drivers/entropy/Kconfig. The redundant ENTROPY_NRF5_RNG deps. are due to redundant 'depends on' within an 'if' in the same file. Tip: Jump to symbols with '/' in the menuconfig and press '?' to check their dependencies. If there are duplicated dependencies, the 'included via ...' path can be handy to discover where they are added. Signed-off-by: Ulf Magnusson <Ulf.Magnusson@nordicsemi.no>

help
This option enables the entropy number generator for ESP32 SoCs.
With Wi-Fi and Bluetooth disabled, this will produce pseudo-entropy
numbers: noise from these radios are used to feed entropy in this
generator.
