Hello,
Thanks everyone for helping. Of the two options, of either using device tree with uboot or using it with the kernel, i have been trying the latter.1. CONFIG_ARM_APPENDED_DTBI am appending the .dtb for my board file to the zImage generated and then using mkimage to get the uImage. The booting stops at the line
2. ARM_ATAG_DTB_COMPAT
3. ARM_ATAG_DTB_COMPAT_CMDLINE_FROM_BOOTLOADER
4. CONFIG_USE_OF
5. CONFIG_MACH_TEGRA20-IRIS-512_DT
"Starting Kernel....". As a result of this, i cannot figure out the exact point of my error. As far as the config file is concerned, i have use the first
option by itself and then tried separately in conjunction with the second and third option as well. I get the same result in each case.
My reason for trying it with the 2nd and 3rd options, was because of the explanation given in Kconfig file at the below link.

It might as well be of the kernel booting silently without any debug console output. but, i have not been able to trace this.
Any suggestions will be helpful.
Thanks & Regards,
Sanchayan.
My original post:
I am compiling kernel image for a Toradex Colibri module which uses the NVidia Tegra2 processor.
The device tree support and files are supplied, which i can see on the below link.
http://lxr.free-electrons.com/source/arch/arm/boot/dts/?a=arm
The file name is tegra20-iris-512.dts which then includes tegra20-colibri-512.dtsi.
I want to know how can i link this while doing "make" for kernel image compilation. This is required as board config file is not present and the device tree has to be used.
Based on my current findings, if the file name is for example exynos4.dts, this will be specified in the config file with CONFIG_MACH_EXYNOS4_DT=y.
I want to know if this is the correct way of specifying a device tree file for which .dtb has been generated?
The kernel version for which i am trying to do this is 3.12.6.
