38c1759fb4 lp-core-uart: Added support for printf to the LP core
This commit adds a minimal logging driver for the LP core. The logging
driver provides a printf function which is built on top of the LP UART
driver. The commit also adds an example to demonstrate how to use print
statements in an LP core program.

RISC-V core during sleep. The commit also adds an example to demonstrate
this feature.

8f93e4d0d5 ulp: Updated ULP CMakeLists.txt to output binary with .elf extension
This commit updates the ULP CMakeLists.txt to output the ULP binary with

4fde033a5f ulp: Added support for RTC I2C driver for ULP RISC-V on esp32s2 and esp32s3
This commit adds support for using the RTC I2C peripheral on the ULP
RISC-V core for esp32s2 and esp32s3. It also adds an example to demonstrate the
usage of the RTC I2C peripheral.

This commit also modifies the rtc_i2c register structure files to enable
the use of bitfields in the ULP RISC-V RTC I2C driver.

ulp: esp32ulp_mapgen: remove the special case for RISC-V, cleanup
There are multiple changes in this commit:

1. Unify the RISC-V and ULP-FSM code paths in esp32ulp_mapgen.py.
   It seems that these were originally introduced because `nm` output
   for the RISC-V case contained symbol sizes, while for the ULP-FSM
   no symbol sizes were reported. This makes sense, because the
   ULP-FSM object files are produced from assembly source, symbol
   sizes have to be added manually using the .size directive.
   In the case of RISC-V, the object files are built from C sources
   and the sizes are automatically added by the compiler.

   Now 'posix' output format is used for both RISC-V and ULP-FSM.

2. Move BASE_ADDR out of esp32ulp_mapgen.py. This now has to be passed
   from CMake, which should make it easier to modify if a new chip
   with a different RTC RAM base address is added.

3. Add C++ guards to the generated header file.

4. Switch from optparse to argparse for similarity with other IDF
   tools.

5. Add type annotations.

ulp: cmake: simplify the dependency on the generated LD script
* "dummy loop to force pre-processed linker file generation" seems to
  be unnecessary. It looks like the idea was copied from the
  dependency of ULP-FSM preprocessed source files on the LD script.
* Can use add_dependencies instead of
  set_target_properties(...LINK_DEPENDS...) which is more readable
* Use target_link_options instead of target_link_libraries, which is
  supported starting from CMake 3.13. Unlike target_link_libraries,
  it doesn't require manually quoting the pats.

ulp: move the expected ULP-FSM toolchain version from .mk to CMake
toolchain_ulp_version.mk is a remnant of the time when we had two
build systems, and CMake had to read the expected version from a
makefile.

there will be a cmake warning:

facab8c5a7 tools: Increase the minimal supported CMake version to 3.16
This updates the minimal supported version of CMake to 3.16, which in turn enables us to use more CMake features and have a cleaner build system.
This is the version that provides most new features and also the one we use in our latest docker image for CI.

4d8a0cce29 ulp: Added support for ULP FSM on esp32s3 and fixed bugs for esp32s2
This commit enables ULP FSM support for esp32s3 and updates ULP FSM code
flow for other chips.
It adds C Macro support for the ULP FSM instruction set on esp32s2 and
esp32s3.
The unit tests are also updated to test ULP FSM on ep32s2 and esp32s3.

2fc9bd61bf ulp: refactor ulp component
This commit refactors the ulp component.
Files are now divided based on type of ulp, viz., fsm or risc-v.
Files common to both are maintained in the ulp_common folder.

This commit also adds menuconfig options for ULP within the ulp
component instead of presenting target specific configuations for ulp.

de798541dc tools: use riscv32-esp-elf toolchain for ESP32-S2 RISC-V ULP
riscv32-esp-elf toolchain (used for ESP32-C3) can also be used for
ESP32-S2 RISC-V ULP coprocessor.

This removes the riscv-none-embed-gcc toolchain which was originally
used for the ULP, and updates the docs and CMake files to use
riscv32-esp-elf.

Some flags are cleaned up and workarounds removed from CMake toolchain
file.

d0b2d5ec95 cmake: Fix for Python files executed directly, not via PYTHON variable
A problem if the Python interpreter used for idf.py (or set via PYTHON
variable) didn't match
"/usr/bin/env python" (or the associated executable for .py files, on
Windows).

Closes https://github.com/espressif/esp-idf/issues/3160
Possibly also fix for https://github.com/espressif/esp-idf/issues/2936

Adds build system test to catch any future direct execution of Python in
the standard build process.
