Torsten Rasmussen 7cc52f88c3 cmake: tfm: moving CMake execution of tfm_cmake to a custom command
Fixes: #36101

The move of CMake invocation to a dedicated custom target, see #34868
results in tfm_cmake to always be considered out-of-date, causing CMake
to be reinvoked in the TF-M Binary dir, which again results in the
build command to rebuild.

This commit moves the invocation to a custom command with the
CMakeCache.txt as output. The custom target tfm_cmake is updated to
depend on CMakeCache.txt.

This mean that CMake for TF-M will only be invoked inside the Zephyr
build command if that file is missing.

If the CMakeCache.txt file is updated or TF-M CMake or source code is
modified, then the build command inside the TF-M build folder will
ensure correct re-run of CMake from within the TF-M build folder.

This ensures that TF-M will still rebuild if TF-M code is modified,
while at the same time avoid unnecessary rebuilds of TF-M code.

Robert Lubos 6ca92495e5 modules: mbedTLS: Add separate Kconfig entry for MBEDTLS_HAVE_TIME_DATE
Currently the MBEDTLS_HAVE_TIME_DATE mbedTLS option is enabled based on
the CONFIG_POSIX_API option. This doesn't seem right, since the enabling
the POSIX API does not guarantee that there is a valid time source in
the system. This was the case for the qemu_x86 platform, where enabling
POSIX_API caused TLS handshake failures due to certificate validation
errors caused by no valid time avaialble in the system.

Fix this by adding a specific KConfig entry for date/time configuration
in mbedTLS. Applications that need to enforce date verification in
mbedTLS should enable it explicitly instead of relying on the
non-obvious implicit configuration.

Ioannis Glaropoulos 81e9ea5cad config: using CONFIG_MBEDTLS_USER_CONFIG_FILE as safeguard
Now using CONFIG_MBEDTLS_USER_CONFIG_FILE instead of
CONFIG_MBEDTLS_USER_CONFIG_ENABLE for inclusion of user config file.

The Kconfig MBEDTLS_USER_CONFIG_ENABLE setting now now determines if
MBEDTLS_USER_CONFIG_FILE is visible.

This removes the problem of MBEDTLS_USER_CONFIG_FILE to be stuck on its
first value.

Users can use MBEDTLS_USER_CONFIG_ENABLE to get the prompt and define
their own value.

As the CONFIG_MBEDTLS_USER_CONFIG_FILE is default promptless then we can
use this setting directly as it will only be defined if another Kconfig
file specifies a default value to use, or user enables:
MBEDTLS_USER_CONFIG_ENABLE.

The MBEDTLS_PROMPTLESS can be set to true whenever configuration of

Similar with CUSTOM_MBEDTLS_CFG_FILE which ensures that user must
explicitly select this symbol before providing a custom mbedTLS config
file.

Today, other parts the Kconfig tree may set a default value for
MBEDTLS_CFG_FILE but that value is stuck and thus changed Kconfig
selections elsewhere in the tree will not adjust the value.

David Brown 4164b17034 modules: mbedtls: Enable PKCS1 v2.1
This Mbed TLS configuration option was being selected based on a
non-existent Kconfig option, and hence would never be defined.  v2.1 of
PKCS1 was published in 2003.  Use of v1.5 has been deprecated since
2016, and should not be used in new or existing designs.

Enable the v2.1 version in any situation where RSA is used for
signatures.  In the future, we should disable v1.5 entirely, but only
after all uses have been determined and possibly corrected.

No significant weaknesses have been found in v1.5, however v2.1 has a
significant security proof.  However, v2.1 does require an entropy
source, which may be an issue in some embedded device situations (which
likely are problematic for other cryptographic reasons).

Torsten Rasmussen b671cf7279 cmake: tfm: support for custom CMake args when building TF-M
This commit allows a subsystem to specify additional CMake flags to be
given to the TF-M build.

The additional CMake flags can be provided through the TFM_CMAKE_OPTIONS
property on the zephyr_property_target.
Using the zephyr_property_target allows Zephyr modules to append extra
TFM_CMAKE_OPTIONS regardless of the CMake processing order.

It splits the ExternalProject_Add into a two step process with the CMake
invocation executed using add_custom_target() and the build process
using ExternalProject_Add(). The reason for this split is because CMake
generator expressions passed through ExternalProject_Add to CMake will
quoted so that `$<TARGET_PROPERTY:<tgt>,<prop>>` becomes
`"-DFOO=bar -DBAR=foo"` instead of `-DFOO=bar -DBAR=foo` which again
results in CMake failures.
