AFAIK, it's a HW limitation of the IXP4xx NPEs, or
possibly Intel's microcode for them.
I run my IXP42x boxes big-endian and don't mind doing so.

Hey again,
Code placement:
Queue Manager & NPE code => arch/arm/mach-ixp4xx
WAN driver code => drivers/net/wan
Eth code => drivers/net/arm
Why would you want such placement?
Potential problems: header files would have to be moved to
include/asm-arm = heade
should still be exposed in arch/arm/mach-
ixp4xx/Kconfig
