New —-list-separator argument of confgen.py and
prepare_kconfig_files.py is used to select which character is used
as list separator. For compatibility with esp-docs, we still keep
support for space separator. Otherwise esp-docs would have to choose
the separator depending on the IDF version.
It can be used in component CMakeLists.txt files when adding "weak"
dependencies between component. A "weak" dependency from A to B is
similar to target_link_libraries(A PRIVATE B), but it gets added only
if B is included in the build.
Use it instead of specifying B as part of PRIV_REQUIRES when the
component can be built (even if with reduced functionality) without
component B being available.
These optional feature produces a graphviz file showing component
dependencies. It is useful for debugging reasons why certain
components got added to the build.
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
This feature was added when we thought that target components might be
added out of IDF tree. That never became possible, and with recent
changes in IDF architecture it is unlikely that this feature will be
necessary any time soon. Remove it, simplifying the code.
This is an experimental feature intended at the moment for ESP-IDF
developers only.
If IDF_TOOLCHAIN=clang environment variable or CMake variable is set,
use toolchain-clang-esp32xx.cmake instead of toolchain-esp32xx.cmake.
These changes aren't sufficient to actually build any IDF project with
clang; subsequent commits add a few workarounds required to do this.
Toolchain files are added for esp32 and esp32s2, which are the targets
supported in our llvm-project fork at the moment.
CMake sorts result of file(GLOB) command since version 3.6.0:
https://gitlab.kitware.com/cmake/cmake/-/commit/edcccde7d
Since ESP-IDF sets cmake_minimum_required version to 3.5, and version
3.5.1 is used in CI, sort file lists obtained from file(GLOB)
manually.
This helps obtain reproducible order of libraries passed to the linker
and to ldgen.
add usb hal/soc, usb_ll files and esp32s3 target for usb
move usb_hal.h into soc common folder
soc/hal: fix soc and periph for usb
tinyusb: fix tinyusb io header
hal: usb_ll fix pull up/down config for esp32s3
soc/hal: fix peripheral addresses
