[Uzair Zaidi]

I am trying to run FALCON MODE on zynq-microzed board. I am following
README-falcon.But when i run `nand read 82000000 kernel` command, i get
this error..

****no devices available****


And when i run u-boot it shows..
**

    > NAND:  zynq_nand_init: Unable detect NAND based on MIO settings ZYNQ
    > NAND init failed

**Here are messages from my u-boot.**
