I Found the answer. The chosen node does not represent a real device, but serves as a place for passing data between firmware and the operating system, like boot arguments. Data in the chosen node does not represent the hardware In the above paragraph, boot arguments are nothing but "kernel command line" arguments.

Hi All,
I have a doubt, how kernel command line parameters are passed to kernel space. Before device tree, we used to pass command line parameters using ATAGS. But after device tree we are not using ATAGS. How we are passing command line parameters to kernel space?
If you are using uboot, please consult uEnv.txt docs. http://linux-sunxi.org/UEnv.txt
This is at U-boot level. where u-boot will write this information?
Thanks & regards,
