1 /* Yaffs commands.
2  * Modified by Charles Manning by adding ydevconfig command.
3  *
4  * Use ydevconfig to configure a mountpoint before use.
5  * For example:
6  *  # Configure mountpt xxx using nand device 0 using blocks 100-500
7  *  ydevconfig xxx 0 100 500
8  *  # Mount it
9  *  ymount xxx
10  *  # yls, yrdm etc
11  *  yls -l xxx
12  *  yrdm xxx/boot-image 82000000
13  *  ...
