+/* 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
+ * ...
