The statement was more in-terms of some ghastly ln -s 
../../../u-boot/include/asm/mux.h kind of stuff which existed in 
x-loader previously, practically making build of x-loader requiring that 
u-boot source be in the same location as the x-loader. yeah, it was 
atrocious, and is one of the steps of breaking that dependency that took 
place.

My 2 cents:
The eventual long term goal is to make u-boot/other alternatives (such 
as OMAP configuration header[1][2]) capable of replacing x-loader. We 
have much to do to reach that stage(while we work on it in parallel).
in the meanwhile, current xfurcation (since there are more than 5 or 6 
different known forks at least) make it impossible to do where we stand 
and what needs to be done.

In a way, considering a single x-loader as a standin solution while a 
final alternative evolves and becomes practical is important and is an 
evolutionary step IMHO.
