I meant the official u-boot from denx.de vs the one FSL ships w/its  
boards & BSPs.  The BSP u-boot has modifications that don't exist in  
the denx.de u-boot (as the quality of the code is not up to open  
source standards).

That is all I meant.

My statement was to convey that the kernel.org kernel should only  
worry itself with the denx.de u-boot (w/regards to compatibility).
