espressif/spi_nand_flash

changelog

## [1.0.0]
### Breaking Changes
- FATFS integration has been moved to a separate `spi_nand_flash_fatfs` component. Projects using FATFS with NAND flash must add `spi_nand_flash_fatfs` as a dependency. FatFs on SPI NAND still requires the **legacy** init path: keep **`CONFIG_NAND_FLASH_ENABLE_BDL` disabled** for that use case (no FatFs-on-BDL support in this release).
- When `CONFIG_NAND_FLASH_ENABLE_BDL` is enabled, the legacy `spi_nand_flash_init_device()` returns `ESP_ERR_NOT_SUPPORTED`. Use `spi_nand_flash_init_with_layers()` instead for block-device consumers.
- `spi_nand_erase_chip()` performs a physical full-media erase. Previously, the driver incorrectly attempted to erase every block without checking bad-block markers, which could erase factory-marked bad blocks. It now skips bad blocks and physically erases only blocks that are not marked bad.

### New Features
- Added Block Device Layer (BDL) support, available from ESP-IDF v6.0. Provides standard `esp_blockdev_t` interfaces for both raw flash access and wear-leveling.
- Added `spi_nand_flash_init_with_layers()` API for layered block device initialization.
- Added page-based API terminology (`read_page`, `write_page`, `get_page_count`, `get_page_size`) with backward-compatible sector aliases.

### Improvements
- Refactor the component for improved structure, maintainability and readability
- Sector API functions are now deprecated aliases for the page API equivalents.

**Migration:** See **Migration Guide (0.x → 1.0.0)** in [layered_architecture.md](layered_architecture.md).

## [0.21.0]
- fix: spi_nand_read fails in case buffer is not DMA aligned (https://github.com/espressif/idf-extra-components/issues/708)

## [0.20.0]
- feat: added support for Gigadevice (GD5F1GM7xExxG) NAND flash

## [0.19.0]
- fix: spi_nand_program_load fails in case buffer is not DMA aligned (https://github.com/espressif/idf-extra-components/issues/684)

## [0.18.0]
- fix: Update esp_vfs_fat_register prototype to esp_vfs_fat_register_cfg to align with ESP-IDF v6.0. The cfg version is now the primary API and remains aliased for compatibility.

## [0.17.0] 
- fix: fix a compilation error caused by the missing freertos/FreeRTOS.h header when building with ESP-IDF v6.0 and later.
- update: improvements to the lower-level APIs following updates in esp_driver_spi.
