The nslu2 itself comes with an ixp4xx CPU, but the armeb port is also
used on a number of ixp2000 boards. Having a big-endian arm distro to
run on the ixp2000 was an important reason for developing this port.
As to why I chose armeb instead of armbe, partially because of the
-EB/-EL thing, partially because the arch name also has the endianity
at the end (armv4b, armv4l, armv5teb, armv5tel), partially because when
I first started porting a distro to armeb, a number of tools (binutils?
I can't remember now.) did accept arm*b-*-* as target string but didn't
The latter might have changed in the meanwhile, but the original
decision to use armeb instead of armbe was made over two years ago.

Please note that there have been lots of issues with armbe (in
configure scripts etc), so I would recommend using armeb.
