This component allows flash operations to be performed by tasks with stacks in PSRAM.
Changelog
## 1.0.2 - fix: Bypass the dispatcher and call the real Flash operations directly when it is not initialized yet, so early-boot Flash access (e.g. partition loading and core dump probing during system startup). ## 1.0.1 - feat: Added `spi_flash_mmap` / `spi_flash_munmap` to the set of Flash APIs intercepted by the dispatcher, so memory-mapping can also be safely invoked from tasks whose stacks live in PSRAM. - fix: Serialize dispatcher requests with an internal mutex so the shared request/result slot is always exclusively owned by a single caller, even when wrappers are called concurrently from different tasks. - fix: Fix on ESP32 the allocator could place these objects into IRAM, causing a `LoadStoreError` on byte accesses. - deprecate: `esp_flash_dispatcher_config_t::queue_size` is kept for backward compatibility only and no longer affects behavior; the dispatcher now uses a single shared slot regardless of the configured value. ## 1.0.0 - Initial release of `esp_flash_dispatcher`. Intercepts `esp_flash_read`, `esp_flash_write`, `esp_flash_write_encrypted`, `esp_flash_erase_region`, and `esp_flash_erase_chip`, and executes them on a dedicated background task whose stack lives in internal RAM, so application tasks can keep their stacks in PSRAM without breaking Flash operations.
