15 - `static int read(long offset, rt_uint8_t *buf, rt_size_t size)`：读取操作
21 |size |待读取数据的大小|
24 - `static int write(long offset, const rt_uint8_t *buf, rt_size_t size)` ：写入操作
30 | size | 待写入数据的大小 |
33 - `static int erase(long offset, rt_size_t size)` ：擦除操作
38 | size | 擦除区域的大小 |
113 #define FAL_ALIGN_UP( size, align ) \
114 ( ( ( size ) + ( align ) - 1 ) - ( ( ( size ) + ( align ) - 1 ) % ( align ) ) )
115 #define FAL_ALIGN_DOWN( size, align ) ( ( ( size ) / ( align ) ) * ( align ) )
119 不难看出 ALIGN_UP是一个size向上取整到align的倍数，ALIGN_DOWN则是向下取整到align的倍数。
