对linux内核创建flash上的各分区源码进行分析

1.注意：内核源码版本为4.9

2.首先注意关键字符串"partitions found on MTD device

这句话在drivers/mtd/mtdpart.c的parse_mtd_partitions()中出现

3.mtd_device_parse_register()调用了parse_mtd_partitions()

4.发现mtd_device_parse_register()中的mtd_add_device_partitions()

5.mtd_add_device_partitions

　　-->add_mtd_partitions

　　　　这里面就有一句 printk(KERN_NOTICE "Creating %d MTD partitions on \"%s\":\n", nbparts, master->name);

6.add_mtd_partitions

　　-->allocate_partition() drivers/mtd/mtdpart.c (对mtd结构体进行初始化)

　　-->add_mtd_device()  drivers/mtd/mtdcore.c

　　-->mtd_add_partition_attrs() drivers/mtd/mtdpart.c
