Hi,
I have noticed and read a few comments regarding the demise of ARCH=ppc.
Having two PowerPC arcitectures and only supprting one of them makes
little sense. Is it not time to migrate (where required) the remaining
code from arch/ppc to arch/powerpc and asm-ppc to asm-powerpc. There are
not many files left that are unique to ARCH=ppc so it should not take too
long.
For me, the requirement is to keep support for the cards indicated in
arch/ppc/config/xxx_defconfig (as I have one that I might what to use with
linux) in the same way as they are supported in ARCH=ppc.
I have just made some tweeks to get ARCH=ppc building for me but I still
need to sort out what is required to get around *** Error: Headers not
exportable for this architecture (ppc).
Regards
Mark Fortescue.

The one thing that is holding up the transition to arch/powerpc is lack
of people with access to the respective boards. If you have one board
that you care about, it would be good if you look into getting it moved
over. Tell us if you have problems doing so. It shouldn't be all that
hard any more, and if it is, maybe some documentation is missing.

You should simply install the headers with ARCH=powerc, even when the
kernel is built with ARCH=ppc. From the user space point of view, there
is only one set of headers.

It's not just lack of boards. It's lack of understanding of the
requirements to get a board port into arch/powerpc. Namely, the device
tree stuff.

It was started in 2005. It's taken too long already.
Bug fixes will still be taken until arch/ppc dies. New platform/board
support, no.

Hi All,
I am currently trying to identify an anoying feature of linux on my
sparc32 systems but I will do some work on the ppc -> powerpc migration
as soon as I have exauhsted my current avenues of investiation on the
sparc32 issue.
Regards
Mark Fortescue.
