Hi Jerry, Thanks for the information.
Please find my understanding about dts: 1. I will have to create board specific *.dts file. 2. Need to download latest dtc compiler. 3. Compile dts file using dtc compiler which will generate *.dtb file 4. Enable following macros in u-boot code #define CONFIG_OF_LIBFDT #define CONFIG_OF_BOARD_SETUP 5. Apart from these macros no code changes in u-boot source code. Thanks, Anup B. On 27-Nov-2009 8:21pm, Jerry Van Baren <[email protected]> wrote:

Hi,
I am porting u-boot on ppc440x5 core based board. I need to support dts in uboot.
As i am new to dts, can anyone please let me know the procedure to support it in uboot?
Thanks,
Anup B.
It is already supported in u-boot.

You will need to create a .dts file to describe your board, compile it with the dtc compiler, and boot using either the 3 parameter version of bootm or using a FIT all-in-one image (preferred).

If you have specific questions after reading the above, ask away.
