/* 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
 *  ...
