Some PowerPC processors can be run in either big or little endian modes, some

This patch set introduces little endian support for the 44x family of PowerPC
processors.
From a community aspect is anyone actually going to use this? Is this going
to be the equivalent of voyager on x86? I've got nothing against some of the
endian clean ups this introduces. However the changes to misc_32.S are a bit
ugly from a readability point of view. Just seems like this is likely to
bit-rot pretty quickly.
I'm with Kumar on this one. Why would we want to support this? I
can't say I would be very willing to help anyone run in LE mode, let
alone have it randomly selectable.
Indeed, I thought we had killed that Windows-NT dog ~15 years ago :-)
Actually this has more to do with having to deal with code written for
ARM LE :-)
The comment was mostly aimed as a remnder of the main reason this was considered
a long time ago.
I understand that the world has moved on, and sadly the vast majority
of hardware is now little endian (although it still baffles me why anyone
would think that way...)
