Description

Added BDL support for esp_ext_part_tables component.

// Reads the partition table from a block device and parses & loads it to `esp_ext_part_list_t` struct
esp_err_t esp_ext_part_list_bdl_read(esp_blockdev_handle_t handle, esp_ext_part_list_t *part_list, esp_ext_part_signature_type_t type, void *extra_args);

// Generates the partition table from `esp_ext_part_list_t` struct and writes it to a block device
esp_err_t esp_ext_part_list_bdl_write(esp_blockdev_handle_t handle, esp_ext_part_list_t *part_list, esp_ext_part_signature_type_t type, void *extra_args);

With these functions which can use a BDL interface, this component can access other storage related components (if they also have a BDL API), e.g. read MBR directly and parse it to esp_ext_part_list.

Generally LGTM, left only few minor comments. Please:

• finish your checklist
• remove Draft once ready to merge

Thanks

Also, please slightly extend the description of this PR - a short explanation why we need these API functions would help. Thank you

Well, thanks for update - I thought the names would be like esp_ext_part_list_write_bdl, not esp_ext_part_list_bdl_write 🙂 (see my note '.. at the end'). Whatever, it's good enough now, let's merge. Thanks for your efforts

[pacucha42]

Approved. The only point - before merging, please, extend the PR's description as requested before
