Initial version of freemodbus master port files have been added to ESP-IDF based on https://github.com/armink/FreeModbus_Slave-Master-RTT-STM32.
The overall repository license, at the time of adding these files, has been BSD 3-clause. However at that time, several port files carried LGPL license headers. As the author of these files confirmed in https://github.com/armink/FreeModbus_Slave-Master-RTT-STM32/issues/61#issuecomment-977828450, this wasn't intentional. ESP-IDF version of modbus master port has been rewritten to target FreeRTOS instead of RT-Thread, but the license headers remained from the original version. This commit corrects this, replacing the license of these files with BSD 3-clause.
Defining CMake variables from the command-line or from another CMake project,
such as `-DCMAKE_C_FLAGS= -DCMAKE_CXX_FLAGS=`, caused a link failure as ESP
CMake was unable to set its proper compilation flags.
Additional CMake compiler flags can now be provided by another project.
* Closes https://github.com/espressif/esp-idf/issues/7507
In commit de22f3a4e5, combination of
hardware and software MPI (bignum) related approach was used to
work around chip (e.g. ESP32-C3) limitation of max 3072 bits support.
This was done using linker "--wrap" flag but since the relevant API is
being used in same translation (compilation unit), hardware mode was not
getting used in some cases (e.g., RSA key generation).
This commit modified internal mbedTLS API and makes software+hardware
combination deterministic.
Updated MQTT submodule: git log --oneline 89894bd0c611b1392967fe90bb49682eba858383...b86d42c130ac64a916ce6cf299d99f9756692394
