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>

arch: high-level Kconfig symbol structure for Trusted Execution This commit contributes a Kconfig symbol hierarchy which allows the user to build Zephyr Secure and Non-Secure images on ARMv8-M MCUs with support for Trusted Execution. However, the high-level configuration structure is generic, thus, can be potentially used for any platform that supports Trusted Execution.

soc: arm: framework for common fixed MPU region configuration We move the configuration of the fixed MPU regions for ARM Cortex-M SoCs in a common place under soc/arm/common/cortex-m, instead of having this configuration present in each ARM SoC or SoC Series definition. The rationale behind this is that for all SoCs the fixed MPU regions configured at SoC definition are only used for enforcing default Flash and SRAM access policies, and currently, this is common to all ARM SoCs with MPU support. We also simplify the Flash and SRAM MPU region definition, aiming at using a single MPU region index to program each of them. We still support the possibility for ARM SoCs to opt-out and, instead, define their own custom fixed MPU regions at SoC definition. We do it using a Kconfig option, introduced explicitly for this purpose. Signed-off-by: Ioannis Glaropoulos <Ioannis.Glaropoulos@nordicsemi.no>

config CPU_HAS_CUSTOM_FIXED_SOC_MPU_REGIONS
bool "Custom fixed SoC MPU region definition"
help
If enabled, this option signifies that the SoC will
define and configure its own fixed MPU regions in the
SoC definition. These fixed MPU regions are currently
used to set Flash and SRAM default access policies and
they are programmed at boot time.

soc: arm: kconfig: Clean up SOC_PART_NUMBER definitions Put a common definition of the SOC_PART_NUMBER symbol in soc/arm/Kconfig, to make it always available for ARM SoCs. Have the other definitions extend the base definition, without repeating the type. Also put the help text on just the base definition. It will show up in the generated documentation and when looking at the symbol information at any of the definition locations in the menuconfig (after going into show-all mode). Trying to get rid of unnecessary "full" symbol definitions in Kconfig.defconfig files, to make the organization clearer. It can also help with finding unused symbols.
