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.
Thanks

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.This is at U-boot level. where u-boot will write this information?______________________________Thanks & regards,Madhu_________________
