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>

# DesignWare SPI driver configuration options
spi: restructure kconfig options () Moves config options for each controllers into their own Kconfig files. This keeps upper level Kconfig from getting too big. () Options for each controller are moved under their own submenus.

license: Replace Apache boilerplate with SPDX tag Replace the existing Apache 2.0 boilerplate header with an SPDX tag throughout the zephyr code tree. This patch was generated via a script run over the master branch. Also updated doc/porting/application.rst that had a dependency on line numbers in a literal include. Manually updated subsys/logging/sys_log.c that had a malformed header in the original file. Also cleanup several cases that already had a SPDX tag and we either got a duplicate or missed updating.

kconfig: Hide the DesignWare SPI driver on unsupported platforms When users are configuring applications they are given the option to enable the DesignWare SPI driver. But they should not be given this option on SoCs that don't have the DesignWare SPI HW. This commit hides the driver by default by introducing the config option HAS_SPI_DW.

menuconfig SPI_DW
drivers/spi: Cleanup the Kconfig files Split QMSI relevant part into its own file. Some config where using prompt, some not: normalizing it by removing the prompt keyword where relevant. Reducing the file by using if/endif when relevant. However, it still not fully clean default: cfg and default baudrate should disappear. There is no default configuration to apply as long as the controller is not configured to run from any part using spi API. Signed-off-by: Tomasz Bursztyka <tomasz.bursztyka@linux.intel.com>

kconfig: drivers: spi: Remove duplicated dependencies The two redundant SPI dependencies are from 'source'ing a file within an 'if SPI' and then adding another 'depends on SPI' within it. 'if FOO' is just shorthand for adding depends on FOO to each item within the 'if'. There are no "conditional includes" in Kconfig, so 'if FOO' has no special meaning around a source. Conditional includes wouldn't be possible, because an if condition could include (directly or indirectly) forward references to symbols not defined yet. Tip: When adding a symbol, check its dependencies in the menuconfig ('ninja menuconfig', then / to jump to the symbol). The menuconfig also shows how the file with the symbol got included, so if you see duplicated dependencies, it's easy to hunt down where they come from.
