SubjectRE: IBM PPC 405 series little endian?
Date
I don't know why you want to run the 405 in LE... but one feature that comes
in handy for me is mapping pages as LE, even though the CPU is running in
BE... this might be what you're looking for.

Well, first, I have to ask, why??

First, if you need to deal with little endian data, on a PPC stwbrx &
lwbrx are your friends.

With the possible exception of the matrox guy, I haven't heard of ANYONE
running in LE mode on ppc. The second problem is going to be to recompile
ALL the applications you want and hope they work.

Finally, if you're doing anything that connects to the internet, remember
that network byte order is big-endian. You might find it interesting that
even Intel is now re-discovering the usefullness of big-endian in some of
their strongarm/Xscale processors.
