Add a new CMake function esp_partition_flash_binary() that provides a
unified API for registering partition data binaries to be flashed. It
replaces the direct esptool_py_flash_target calls scattered across
components (spiffs, fatfs, nvs_flash) with a single function that:
- Resolves partition offset from the partition table automatically
- Determines encryption requirements (auto-detect or ALWAYS_PLAINTEXT)
- Creates per-partition flash targets (e.g. idf.py <partition>-flash)
- Optionally includes the binary in `idf.py flash` via FLASH_IN_PROJECT
On the linux target, the function registers binaries for pre-loading
into the emulated flash. A build-time manifest (linux_flash_data.txt)
is generated via file(GENERATE), and partition_linux.c reads it at
runtime to copy each binary into the memory-mapped flash buffer at
the correct offset.
The partition_ops example is updated to use the new function and
includes a custom_partition with pre-built data to demonstrate the
full workflow, including on the linux target.
spiffs_res_to_errno maps `SPIFFS_ERR_END_OF_OBJECT` to EIO which breaks the common contract where
errno should be 0 if readdir iterated through all the entries in a directory.
The fix is explicitly checking for `SPIFFS_ERR_END_OF_OBJECT` and in that case set errno to 0.
This commit establishes the foundation for making the esptool_py
component idempotent.
The following changes are made in this commit:
- Removes unnecessary dependency of esp_wifi component on esptool_py.
- Add missing esptool_py dependencies to components which directly use
esptool_py specific functions or variables but do not declare a public
or private dependency.
This commit replaces the use of portNUM_PROCESSORS and configNUM_CORES
macros in all of ESP-IDF. These macros are needed to realize an SMP
scenario by fetching the number of active cores FreeRTOS is running on.
Instead, a new Kconfig option, CONFIG_FREERTOS_NUMBER_OF_CORES, has been
added as a proxy for the FreeRTOS config option, configNUMBER_OF_CORES.
This new commit is now used to realize an SMP scenario in various places
in ESP-IDF.

ADDITIONAL_MAKE_CLEAN_FILES is deprecated and only worked with make.
Replaced with the new ADDITIONAL_CLEAN_FILES (CMake 3.15) which also works with ninja.
This fixes the issue that "idf.py partition-table" had to be run
manually in order for the partition table to be generated, when
building for linux target.
