/* Yaffs commands.
* Modified by Charles Manning by adding ydevconfig command.
*
* Use ydevconfig to configure a mountpoint before use.
* For example:
* # Configure mountpt xxx using nand device 0 using blocks 100-500
* ydevconfig xxx 0 100 500
* # Mount it
* ymount xxx
* # yls, yrdm etc
* yls -l xxx
* yrdm xxx/boot-image 82000000
* ...
