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: introduce Kconfig option for Nordic IDAU This commit introduces a new Kconfig symbol to signify that a CPU implements the Nordic-specific security attribution unit. The symbol is meant to be selected by Nordic SoCs that implement the System Protection Unit (SPU) peripheral. Signed-off-by: Ioannis Glaropoulos <Ioannis.Glaropoulos@nordicsemi.no>

ARM terminology).
soc: arm: Kconfig option to indicate double-precision FP This commit introduces a Kconfig option for ARM SoCs, to signify that the SoC implements a double-precision floating point unit. The option is utilized in cmake/fpu-for-gcc-m-cpu to select the appropriate GCC compile option flag for FPU. Signed-off-by: Ioannis Glaropoulos <Ioannis.Glaropoulos@nordicsemi.no>

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.

config SOC_PART_NUMBER
string
help
This string holds the full part number of the SoC. It is a hidden option
that you should not set directly. The part number selection choice defines
the default value for this string.
