[Ltib] updating the kernel

[B.J. Buchalter]

So, related to, but different from my previous question: I am working  
with a freescale ltib BSP (for the MPC8377).

The kernel version in that BSP is 2.6.25

There has been a bunch of development in the firewire drivers in the  
kernel. Merging in the changes to FireWire into the 2.6.25 kernel  
looks to be non-trivial since there have been substantial changes to  
the kernel SPIs.

What is involved in bringing up a new version of the kernel within a  
given BSP or LTIB if there is no direct support for it yet?

Is it worth my time (as a relative newbie) to try to get 2.6.30  
building for my board? If so, is there any guide to doing it?

It looks to me like I will need to make changes to the FireWire driver  
in the kernel, but that seems to be kind of a waste of time if I make  
the changes on an old version of the kernel, as then there would be no  
real way to get the changes/fixes into the main line. But it doesn't  
make sense to be working on the head if I can't get it to build for my  
target...

Thanks!
