Hello all,
The AVR32 architecture is not keeping up with the development of the kernel,
and since it shares so much of the drivers with Atmel ARM SoC, it is starting
to hinder these drivers to develop swiftly.
Also, all AVR32 AP7 SoC processors are end of lifed from Atmel (now
Microchip).
Finally, the GCC toolchain is stuck at version 4.2.x, and has not received
any patches since the last release from Atmel;
4.2.4-atmel.1.1.3.avr32linux.1. When building kernel v4.10, this toolchain is
no longer able to properly link the network stack.
Haavard and I have came to the conclusion that we feel keeping AVR32 on life
support offers more obstacles for Atmel ARMs, than it gives joy to AVR32
users. I also suspect there are very few AVR32 users left today, if anybody
at all.
I have prepared three patches in my for-linus branch in git tree
https://git.kernel.org/cgit/linux/kernel/git/egtvedt/linux-avr32.git
Shortlog below, patches not inlined as they are quite large IMHO.
I will send a formal pull request to Linus unless anybody objects loudly.
I have also prepare patches for removing AVR32 specific kernel drivers, I
will send those to the relevant subsystem maintainers.
Hans-Christian Noren Egtvedt (3):
avr32: remove support for AVR32 architecture
docs: remove all references to AVR32 architecture
scripts: remove AVR32 support from checkstack.pl

Not sure it has any value since I'm not the maintainer of this platform,

It will definitively help to remove some of the non-DT code in all our
former-common drivers.

Quick look at the patches (file path mostly) seems okay:

And thanks a lot to Haavard and you Hans-Christian for having developed,
more than 10 years ago, and then maintained some of the nice early
drivers that we are still using for our ARM-based platforms!

Thank you for keeping it alive for so long!
I looked through you tree superficially. There are a few references to
AVR32 remaining. Most of them are for other subsystems, but you could
consider picking up a couple of more for your patchset:
include/uapi/linux/elf-em.h still defines EM_AVR32. This could be
considered a part of the architecture code.
lib/Kconfig.debug has a list of architectures which want frame
pointers. You could probably remove AVR32 from that list.
mm/Kconfig has a special case for AVR32 needing two quicklists.
If you were planning to patch each of those separately later, please
ignore my comments.

My git grep magic did not catch this.

Same.
Will add a patch for these two.

This one I have in a different series, the one I planned to push to various
maintainers after the initial removal.

Is this still planned for 4.12?

Yes, I have received no objections, only feedback to bits and pieces in
generic areas that can be removed in addition to my initial patch.
