2025-02-27mbedtls: refactor mbedtls build for XPLRaymond Mao
Refactor the entire kconfig page for mbedtls, adapt mbedtls makefile and default config file using 'XPL_', in order to have independent mbedtls kconfig options in U-Boot Proper, SPL, TPL and VPL. User can choose legacy or mbedtls libraries for them independently. Set mbedtls native hashing libraries as default when MBEDTLS_LIB, SPL_MBEDTLS_LIB, TPL_MBEDTLS_LIB or VPL_MBEDTLS_LIB is selected. If users prefer using U-Boot legacy hashing libraries, please select MBEDTLS_LIB_HASHING_ALT, SPL_MBEDTLS_LIB_HASHING_ALT, TPL_MBEDTLS_LIB_HASHING_ALT or VPL_MBEDTLS_LIB_HASHING_ALT for U-Boot Proper, SPL, TPL and VPL respectively. Moreover, rename a few kconfig options and update their descriptions to improve the consistency of terminology.

2024-12-06mbedtls: remove MBEDTLS_HAVE_TIMEIlias Apalodimas
When MbedTLS TLS features were added MBEDTLS_HAVE_TIME was defined as part of enabling https:// support. However that pointed to the wrong function which could crash if it received a NULL pointer. Looking closer that function is not really needed, as it only seems to increase the RNG entropy by using 4b of the current time and date. The reason that was enabled is that lwIP was unconditionally requiring it, although it's configurable and can be turned off. Since lwIP doesn't use that field anywhere else, make it conditional and disable it from our config.

2024-11-12mbedtls: Enable TLS 1.2 supportIlias Apalodimas
Since lwIP and mbedTLS have been merged we can tweak the config options and enable TLS1.2 support. Add RSA and ECDSA by default and enable enough block cipher modes of operation to be comatible with modern TLS requirements and webservers Reviewed-by: Raymond Mao <raymond.mao@linaro.org> Acked-by: Jerome Forissier <jerome.forissier@linaro.org> Signed-off-by: Ilias Apalodimas <ilias.apalodimas@linaro.org>
2024-10-14mbedtls: Enable smaller implementation for SHA256/512Raymond Mao
Smaller implementation for SHA256 and SHA512 helps to reduce the ROM footprint though it has a certain impact on performance. As a trade-off, enable it as a default config when MbedTLS is enabled can reduce the target size significantly with acceptable performance loss.

2024-10-14mbedtls: add mbedtls into the build systemRaymond Mao
Port mbedtls with adapted libc header files. Add mbedtls default config header file. Optimize mbedtls default config by disabling unused features to reduce the target size. Add mbedtls kbuild makefile. Add Kconfig skeleton and config submenu entry for selecting crypto libraries between mbedtls and legacy ones. Add the mbedtls include directories into the build system. Port u-boot hash functions as MbedTLS crypto alternatives and set it as default. Subsequent patches will separate those Kconfigs into pairs of _LEGACY and _MBEDTLS for controlling the implementations of legacy crypto libraries and MbedTLS ones respectively. The motivation of moving and adapting *INT* macros from kernel.h to limits.h is to fulfill the MbedTLS building requirement. The conditional compilation statements in MbedTLS expects the *INT* macros as constant expressions, thus expressions like `((int)(~0U >> 1))` will not work. Prerequisite ------------ This patch series requires mbedtls git repo to be added as a subtree to the main U-Boot repo via: $ git subtree add --prefix lib/mbedtls/external/mbedtls \ https://github.com/Mbed-TLS/mbedtls.git \ v3.6.0 --squash Moreover, due to the Windows-style files from mbedtls git repo, we need to convert the CRLF endings to LF and do a commit manually: $ git add --renormalize . $ git commit Signed-off-by: Raymond Mao <raymond.mao@linaro.org>
