對linux核心建立flash上的各分割槽原始碼進行分析

1.注意：核心原始碼版本為4.9
2.首先注意關鍵字串"partitions found on MTD device
這句話在drivers/mtd/mtdpart.c的parse_mtd_partitions()中出現
3.mtd_device_parse_register()呼叫了parse_mtd_partitions()
4.發現mtd_device_parse_register()中的mtd_add_device_partitions()
5.mtd_add_device_partitions
-->add_mtd_partitions
這裡面就有一句 printk( KERN_NOTICE "Creating %d MTD partitions on \"%s\":\n", nbparts, master->name);
6.add_mtd_partitions
-->allocate_partition() drivers/mtd/mtdpart.c (對mtd結構體進行初始化)
-->add_mtd_device() drivers/mtd/mtdcore.c
-->mtd_add_partition_attrs() drivers/mtd/mtdpart.c
