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
