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>

# Flash Circular Buffer module
fs: fcb: add option to disable CRC for fcb entries Add option to disable CRC for fcb entries. This improves the write throughput significantly at the cost of not detecting corrupted data in flash. This is beneficial for aplications that needs the extra write throughput, where error detection is done elsewhere. Allow the FCB entries in flash to have a valid CRC when CRC is disabled in the FCB. This allows existing solutions to disable CRC checking, while keeping the CRC areas intact. Note that this is a one-way option.

subsys: fs: Add Flash Circular Buffer Zephyr already supports NFFS as a storage layer, but it might be a little bit too heavyweight for certain applications in memory-restricted ICs. This module is response for need of Lightweight flash storage capability. FCB is ported form MyNewt as native zephyr module. Signed-off-by: Andrzej Puzdrowski <andrzej.puzdrowski@nordicsemi.no>

subsys: kconfig: Remove 'default n' properties and clean up a bit Bool symbols implicitly default to 'n'. A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you want to override a 'default y' on the base definition of the symbol. It isn't used like that on any of these symbols though. Remove some 'default ""' properties on string symbols too. Also make definitions more consistent by converting some config FOO <type> prompt "foo" definitions to a shorter form: config FOO <type> "foo" This shorthand works for int/hex/string symbols too, not just for bool symbols.

crc: Make the build of crc function dependent on a Kconfig Add CONFIG_CRC for building CRC related routines. CRC routines are now being built for each application, whether used or not and are add in the build system unconditionally. Keep CONFIG_CRC enabled by default for now and until all users have converted to use the new option. Partial fix for #50654 Signed-off-by: Anas Nashif <anas.nashif@intel.com>

flash: Move dependency on FLASH_PAGE_LAYOUT where it belongs The commit adds dependency on Kconfig FLASH_PAGE_LAYOUT to subsystems that really require it: FCB, NVS, LittleFS and removes direct selection from '*.conf' files where no longer needed.

This allows the FCB instances to disable CRC checks in
favor of increased write throughput.
