[ELDK] U-Boot for the MX51

[V S]

I am trying to get started with compiling freescale's MX51 U-Boot. 

I am following the steps as detailed in 

http://cache.freescale.com/files/dsp/doc/app_note/AN4173.pdf?fpsp=1&WT_TYPE=Application%20Notes&WT_VENDOR=FREESCALE&WT_FILE_FORMAT=pdf&WT_ASSET=Documentation


I am downloading the file named 

L2.6.35_10.11_ER_source_bundle.tar.gz

Is that the steps in right direction for building u-boot for MX51 ?
