The help text doesn't mention out-of-tree providers.
Noup since Ironside not available upstream and it is required for PSA RNG. This enables the PSA RNG as the default Zephyr entropy provider for the nrf54h20dk cpuapp and cpurad targets. Signed-off-by: Georgios Vasilakis <[email protected]>
…PTO_PSA The dependency should be PSA_CRYPTO_CLIENT and not MBEDTLS_PSA_CRYPTO_CLIENT because the former is more generic. TF-M can indeed provide PSA Crypto API, not only Mbed TLS. Upstream PR: 96415 Signed-off-by: Valerio Setti <[email protected]>
…_PSA_CRYPTO_C The driver code only relies on legacy Mbed TLS crypto, not on PSA API, so enabling MBEDTLS_PSA_CRYPTO_C is not needed here. Upstream PR: 96415 Signed-off-by: Valerio Setti <[email protected]>
…_C in BT_SILABS_EFR32 The driver only uses psa_generate_random() so ENTROPY_C is not required. Upstream PR: 96415 Signed-off-by: Valerio Setti <[email protected]>
…YPTO The goal of new Kconfig PSA_CRYPTO_PROVIDER is to automatically enable any of the PSA Crypto API provider available for the platform without having the user to manually pick the proper one. This provider can be either TF-M, if that's enabled in the build, or Mbed TLS otherwise. PSA_CRYPTO_PROVIDER simplifies also modules/subsystem Kconfigs removing blocks as: select MBEDTLS if !BUILD_WITH_TFM select MBEDTLS_PSA_CRYPTO_C if !BUILD_WITH_TFM Kconfig PSA_CRYPTO_PROVIDER_CUSTOM is also added to allow the end user to add a custom implementation of PSA Crypto API instead of TF-M or Mbed TLS ones.
