This is not correct. You can not use the DDR settings from mx51evk
directly into mx35pdk.

You would need to create a imximage.cfg for mx35pdk.

Take a look at Freescale U-boot as a reference:
http://opensource.freescale.com/git?p=imx/uboot-imx.git;a=blob;f=board/freescale/mx35_3stack/flash_header.S;h=b662669f80061be18787eafea6eb3668786b6224;hb=329240314138de1fb8d3d08531e0c3408482972f

With these values you can create a correct imximage.cfg file for mx35pdk.

Currently mx35pdk does not support internal boot mode and that is the
reason you don't find a imximage currently.

So my suggestion for you is to try to boot from internal boot mode
first. Try booting from SD card first as this would be easier.

Once you managed to boot from SD card, you will be also able to boot
it from SPI NOR.
