[Buildroot] Using a different kernel tree ?

[Guillaume Dargaud]

Hello all,
I'd like to use, within buildroot, the kernel tree from 
git://git.xilinx.com/linux-2.6-xlnx.git instead of the vanilla tree coming 
with buildroot.

How does one do that ?

If I just replace toolchain_build_ppc/linux-2.6.24 and/or 
project_build_ppc/my_project/linux-2.6.24 with the Xilinx tree, on the next 
"make ARCH=ppc linux26-menuconfig" it just deletes the whole directory and 
rebuilds it from bzcat...

Or are there alternatives if I want to use the nice toolchain built by 
buildroot ?


BTW, what is the difference between toolchain_build_ppc/linux-2.6.24 and 
project_build_ppc/my_project/linux-2.6.24 ?
