/* 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
   *  ...
