```   我对于SFDP中的这些参数如何进行修改和实现与SFUD框架的对接，以及关于FLASH的各种操作指令与下面红色代码的对接不太明白，不知道是不是会有一期答疑直播课将一下关于SFUD的移植？或者哪位小伙伴能帮我解答一下

typedef struct {
   bool available;                              /**< available when read SFDP OK */
   uint8_t major_rev;                           /**< SFDP Major Revision */
   uint8_t minor_rev;                           /**< SFDP Minor Revision */
   uint16_t write_gran;                         /**< write granularity (bytes) */
   uint8_t erase_4k;                            /**< 4 kilobyte erase is supported throughout the device */
   uint8_t erase_4k_cmd;                        /**< 4 Kilobyte erase command */
   bool sr_is_non_vola;                         /**< status register is supports non-volatile */
   uint8_t vola_sr_we_cmd;                      /**< volatile status register write enable command */
   bool addr_3_byte;                            /**< supports 3-Byte addressing */
   bool addr_4_byte;                            /**< supports 4-Byte addressing */
   uint32_t capacity;                           /**< flash capacity (bytes) */
  struct {
       uint32_t size;                           /**< erase sector size (bytes). 0x00: not available */
       uint8_t cmd;                             /**< erase command */</font>
   } eraser[SFUD_SFDP_ERASE_TYPE_MAX_NUM];      /**< supported eraser types table */
   //TODO lots of fast read-related stuff (like modes supported and number of wait states/dummy cycles needed in each)
} sfud_sfdp, *sfud_sfdp_t;

这家伙很懒，什么也没写！
