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.
This commit reorganizes SPI flash header files to better reflect their
visibility and intended usage:
1. Rename `esp_flash_port/` to `esp_flash_chips/`:
- Better reflects that these headers are for chip driver implementations
- All chip driver headers moved to `esp_flash_chips/` directory
- Added README.md explaining semi-public nature of these headers
2. Move internal headers to `esp_private/`:
- `esp_flash_internal.h` -> `esp_private/esp_flash_internal.h`
- `memspi_host_driver.h` -> `esp_private/memspi_host_driver.h`
3. Move chip driver related headers to `esp_flash_chips/`:
- `esp_private/esp_flash_types.h` -> `esp_flash_chips/esp_flash_types.h`
- `spi_flash/spi_flash_defs.h` -> `esp_flash_chips/spi_flash_defs.h`
- `spi_flash_override.h` -> `esp_flash_chips/spi_flash_override.h`
- All `spi_flash_chip_*.h` headers moved to `esp_flash_chips/`
4. Code improvements:
- Remove unused includes (e.g., `spi_flash_override.h` from `cache_utils.c`)
- Use public API `esp_flash_get_size()` instead of direct member access
- Add `esp_flash_is_quad_mode` to linker.lf for IRAM placement
5. Documentation updates:
- Add README.md in `esp_flash_chips/` explaining semi-public headers
- Update programming guide with warnings about internal headers
- Update both English and Chinese documentation
6. Update all references across the codebase:
- Update includes in `spi_flash` component
- Update `bootloader_support`, `app_update`, `esp_tee`, `espcoredump`
- Update example projects
Breaking changes:
- Headers moved to new locations require include path updates
- `custom_flash_driver` example temporarily disabled until external
components are updated
Add a new example showcasing how to obtain and interpret statistics
about the usage of an NVS partition.
Also demonstrates how stats change after writing some key-value pairs
in 2 separate namespaces.
feat(sdspi): Add an option to modify the waiting time for MISO before sending next command
Closes IDFGH-15977 and IDFGH-9089

Ensure that enum values are used When assigning `pull_up_en` and `pull_down_en`
fields of `gpio_config_t`. Helps avoid `invalid conversion` errors when
building those code snippets in C++.
feat(storage): Update emmc and perf_benchmark example to work with ESP32-P4, fix SDMMC slot deinit bug in legacy driver
Closes IDF-13394 and IDF-13483
