+This directory contains example configuration files.
+
+The examples are generally focused on a particular usage case (eg, support for
+a restricted number of ciphersuites) and aim at minimizing resource usage for
+this target. They can be used as a basis for custom configurations.
+
+These files are complete replacements for the default mbedtls_config.h. To use one of
+them, you can pick one of the following methods:
+
+1. Replace the default file include/mbedtls/mbedtls_config.h with the chosen one.
+
+2. Define MBEDTLS_CONFIG_FILE and adjust the include path accordingly.
+   For example, using make:
+
+    CFLAGS="-I$PWD/configs -DMBEDTLS_CONFIG_FILE='<foo.h>'" make
+
+   Or, using cmake:
+
+    find . -iname '*cmake*' -not -name CMakeLists.txt -exec rm -rf {} +
+    CFLAGS="-I$PWD/configs -DMBEDTLS_CONFIG_FILE='<foo.h>'" cmake .
+    make
+
+Note that the second method also works if you want to keep your custom
+configuration file outside the Mbed TLS tree.

+Summary
+-------
+
+The two files:
+
+* crypto_config_profile_medium.h
+* tfm_mbedcrypto_config_profile_medium.h
+
+are copyright The Mbed TLS Contributors, and are distributed under the license normally

+
+Background
+----------
+
+The two files crypto_config_profile_medium.h and tfm_mbedcrypto_config_profile_medium.h
+are taken verbatim from the TF-M source code here:

+We only retain the note at the top of the files because we are taking the files verbatim, for ease of

+ * Uncomment to enable p256-m. This is an alternative implementation of

+ * Compared to the default implementation:
+ *
+ * - p256-m has a much smaller code size and RAM footprint.
+ * - p256-m is only available via the PSA API. This includes the pk module
+ *   when #MBEDTLS_USE_PSA_CRYPTO is enabled.
+ * - p256-m does not support deterministic ECDSA, EC-JPAKE, custom protocols
+ *   over the core arithmetic, or deterministic derivation of keys.
+ *
+ * We recommend enabling this option if your application uses the PSA API
+ * and the only elliptic curve support it needs is ECDH and ECDSA over
+ * SECP256R1.
+ *
+ * If you enable this option, you do not need to enable any ECC-related
+ * MBEDTLS_xxx option. You do need to separately request support for the
+ * cryptographic mechanisms through the PSA API:
+ * - #MBEDTLS_PSA_CRYPTO_C and #MBEDTLS_PSA_CRYPTO_CONFIG for PSA-based
+ *   configuration;
+ * - #MBEDTLS_USE_PSA_CRYPTO if you want to use p256-m from PK, X.509 or TLS;
+ * - #PSA_WANT_ECC_SECP_R1_256;
+ * - #PSA_WANT_ALG_ECDH and/or #PSA_WANT_ALG_ECDSA as needed;
+ * - #PSA_WANT_KEY_TYPE_ECC_PUBLIC_KEY, #PSA_WANT_KEY_TYPE_ECC_KEY_PAIR_BASIC,
+ *   #PSA_WANT_KEY_TYPE_ECC_KEY_PAIR_IMPORT,
+ *   #PSA_WANT_KEY_TYPE_ECC_KEY_PAIR_EXPORT and/or
+ *   #PSA_WANT_KEY_TYPE_ECC_KEY_PAIR_GENERATE as needed.
+ *
+ * \note To benefit from the smaller code size of p256-m, make sure that you
+ *       do not enable any ECC-related option not supported by p256-m: this
+ *       would cause the built-in ECC implementation to be built as well, in
+ *       order to provide the required option.
+ *       Make sure #PSA_WANT_ALG_DETERMINISTIC_ECDSA, #PSA_WANT_ALG_JPAKE and
+ *       #PSA_WANT_KEY_TYPE_ECC_KEY_PAIR_DERIVE, and curves other than
+ *       SECP256R1 are disabled as they are not supported by this driver.
+ *       Also, avoid defining #MBEDTLS_PK_PARSE_EC_COMPRESSED or
+ *       #MBEDTLS_PK_PARSE_EC_EXTENDED as those currently require a subset of
+ *       the built-in ECC implementation, see docs/driver-only-builds.md.
