* add NO_LTO option to make
* add linkermap submodule and linkermap target
* add linkermap to ci build
* linkermap doesn't work with esp32sx map file yet
* add note for linkermap target
- added back pre-existing board directories which now just select PICO_BOARD
- added boards/pico_sdk which just uses the pre-existing PICO_BOARD setting
- fixed rp2040/family.cmake to include the magic string "CFG_TUSB_MCU=OPT_MCU_RP2040" expected by build_family.py
- Examples should be CMake buildable from their own subdirectory; such a build will error out based on
matching .skip.MCU_xxx or a mismatched .only.MCU_
- It should be possible to build from a higher level and use .skip.MCU_ and .only.MCU_ to filter which
examples get built
- The intention is for the CMakeLists.txts in the examples to be non family specific and without MCU based IFs. I have
started this work, but am not really sure the state of the esp32 stuff; in any case the plan is to have
everything encapsulated in the FAMILY/family.cmake
- pico_examples now just includes examples/device/CMakeLists.txt and examples/host/CMakeLists.txt directly, as they
also build correctly when included from there.
Note that .skip.MCU_ for esp32 in the directories it wasn't previously avaiable has not been added, as the .skip is common to the regular Makefile builds also. It isn't clear whether these examples should build for esp32, but if not .skip should be added.
`hw\bsp` separate one family folder to esp32s2, esp32s3
add board specific board.cmake file to override board specific options(features)
fix examples and test scripts to use new family approach
add support of new esp32s3 target and the board
update the roles.mk wrapper to allow dfu flashing of espressif chip
update examples to allow compilation for esp32s3_addax_1 board
once the code is tested the PR to original tinyusb repo will be submitted
