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>

# Atmel SAM0 flash driver config
flash: add a driver for the internal flash on the SAM0 series. The SAM0 has a 64 byte page (the programing unit) with 4 pages to a row (the erase unit). This driver implements a read/modify/write to emulate the byte level writes used by NFFS. Signed-off-by: Michael Hope <mlhx@google.com>

menuconfig SOC_FLASH_SAM0
Kconfig: Use a short, consistent style for prompts Consistently use config FOO bool/int/hex/string "Prompt text" instead of config FOO bool/int/hex/string prompt "Prompt text" (...and a bunch of other variations that e.g. swapped the order of the type and the 'prompt', or put other properties between them). The shorthand is fully equivalent to using 'prompt'. It saves lines and avoids tricking people into thinking there is some semantic difference. Most of the grunt work was done by a modified version of https://unix.stackexchange.com/questions/26284/ how-can-i-use-sed-to-replace-a-multi-line-string/26290#26290, but some of the rarer variations had to be converted manually.

kconfig: Replace some single-symbol 'if's with 'depends on' I think people might be reading differences into 'if' and 'depends on' that aren't there, like maybe 'if' being needed to "hide" a symbol, while 'depends on' just adds a dependency. There are no differences between 'if' and 'depends on'. 'if' is just a shorthand for 'depends on'. They work the same when it comes to creating implicit menus too. The way symbols get "hidden" is through their dependencies not being satisfied ('if'/'depends on' get copied up as a dependency on the prompt). Since 'if' and 'depends on' are the same, an 'if' with just a single symbol in it can be replaced with a 'depends on'. IMO, it's best to avoid 'if' there as a style choice too, because it confuses people into thinking there's deep Kconfig magic going on that requires 'if'. Going for 'depends on' can also remove some nested 'if's, which generates nicer symbol information and docs, because nested 'if's really are so simple/dumb that they just add the dependencies from both 'if's to all symbols within. Replace a bunch of single-symbol 'if's with 'depends on' to despam the Kconfig files a bit and make it clearer how things work. Also do some other minor related dependency refactoring. The replacement isn't complete. Will fix up the rest later. Splitting it a bit to make it more manageable. (Everything above is true for choices, menus, and comments as well.) Detected by tweaking the Kconfiglib parsing code. It's impossible to detect after parsing, because 'if' turns into 'depends on'. Signed-off-by: Ulf Magnusson <Ulf.Magnusson@nordicsemi.no>

subsys: storage: flash_map: enable only if any flash driver is enable It was possible to have enable flash module while no flash driver implementation was enabled. This cause coverity issues and unnecessary initialization call. This pat introduce FLASH_HAS_DRIVER_ENABLED Kconfig keyword which is selected once any flash driver is enabled. flash_map switch its dependency to this keyword.

help
kconfig: Global whitespace/consistency cleanup Clean up space errors and use a consistent style throughout the Kconfig files. This makes reading the Kconfig files more distraction-free, helps with grepping, and encourages the same style getting copied around everywhere (meaning another pass hopefully won't be needed). Go for the most common style: - Indent properties with a single tab, including for choices. Properties on choices work exactly the same syntactically as properties on symbols, so not sure how the no-indentation thing happened. - Indent help texts with a tab followed by two spaces - Put a space between 'config' and the symbol name, not a tab. This also helps when grepping for definitions. - Do '# A comment' instead of '#A comment' I tweaked Kconfiglib a bit to find most of the stuff. Some help texts were reflowed to 79 columns with 'gq' in Vim as well, though not all, because I was afraid I'd accidentally mess up formatting.
