async memcpy: support async memcopy on esp32s2/s3 Added async memory copy API: on esp32-s2, the implementation is based on CP_DMA on esp32-s3, the implementation is based on GDMA 2020-09-08 08:17:18 -04:00			`idf_component_register(SRCS "esp_async_memcpy.c" "panic.c" "system_api.c" "startup.c" "sleep_modes.c" "system_time.c"`

esp_system: startup flow modifications Changes the startup flow to the ff: hardware -> core libraries init -> other libraries init -> os init (optional) -> app_main - hardware init resides in the port layer, and is the entry point - core libraries init executes init functions of core components - other libraries init executes init functions of other components (weak references) - after other lib is init, the app_main function is called, however, an OS can wrap the real call to app_main to init its own stuff, and then call the real app_main 2020-02-05 09:40:15 -05:00			`PRIV_REQUIRES spi_flash app_update`

esp_system: introduce intermediary function to call after system init This MR uses an intermediary function `start_app` to call after system initialization instead of `app_main`. In RTOS builds, freertos provides `start_app` and calls `app_main`. In non-RTOS builds, user provides `start_app` directly. 2020-06-10 09:13:31 -04:00			# After system initialization, `start_app` (and its other cores variant) is called.

esp_system: restore deleted no stack check flag Restores the change of startup refactor changes removed the no stack check protection flag when compiling the source file that contains execution of constructors - which contains function to setup stack guard. Restore that and update the source file, since this is in the 2nd stage of the startup now. Closes https://github.com/espressif/esp-idf/issues/5617 2020-07-21 06:11:22 -04:00			`endif()`
