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 * ...
