Hello Everyone,
I'm looking for some information about the Extended Addressing Mode
(XAEN bit of HID0 register) of PPC32 support in Linux.
I do not see anything in the main kernel tree but there may be some
patches available ?
Any information will be appreciate.
Regards.
There are patches from Becky Bruce that are going into 2.6.28. What
are you needing >32-bit for? There are some SW IO MMU changes that
are still pending to complete this work.

We are developing a board based on Freescale 8641D which can get 4GB of
ram. So I need 4GB+IOs (~1GB) of physical addressing space.
My plan is to put a part of this ram above of 4GB to keep accesses to
the IOs below the 4GB limit. It means non-contiguous ram addressing and
XAEN features to be working.
Where can I glance through Becky patches ?
