Open Firmware - dts file

[Siva Prasad]

Hi,

I am trying to understand ..

1) How a given dts file is embedded into the zImage (how about vmlinux?)
2) Where does it get stored for later access during booting?
3) How a specific dts file out of the available in /boot/dts directory
is chosen?

I am a newbie to this open firmware thing and looking for the right
pointer to get started.

Thanks in advance
