[U-Boot] Using U-boot on the IXP432

[David Milway]

Hi,
 
I have been using a board with and IXP432 for about a year now, starting
with Redboot
but running in big endian mode. 
I am now looking at using u-boot for network booting but I would like to
run it in little endian mode.
Before I get stuck into to porting the code I have a few questions.
 
1) Has anybody else ported the code to the IXP432?
2) Is there any reason that the IXP cpu configuration sets the bigendian
flag and should it be possible 
just to set it to little endian and will the bulk of the code work
without modification?
 
Thanks
 
Dave
