you code is wrong : you can't access the physical memory as there is
MMU. You can check in the code how this is done.

The following link may me also be of interest :

meta-fsl-arm is not the right place for this kind of generic
kernel question, you should ask on kernel related mailing lists such as 
for ARM :
http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
for beginners :
