Now that arch/metag/ has been removed, remove the METAG dependency from
the IMG IR device driver. The hardware is also present on MIPS SoCs so
the driver still has value.

Since I brought up the architecture removal independently, I could
pick this up into a git tree that also has the removal of some of the
other architectures.
I see your tree is part of linux-next, so you could also just put it
in there and send a pull request at the merge window if you prefer.
The only real reason I see for a shared git tree would be to avoid
conflicts when we touch the same Kconfig files or #ifdefs in driver,
but Meta only appears in
config FRAME_POINTER
bool "Compile the kernel with frame pointers"
depends on DEBUG_KERNEL && \
(CRIS || M68K || FRV || UML || \
SUPERH || BLACKFIN || MN10300 || METAG) || \
ARCH_WANT_FRAME_POINTERS
and
include/trace/events/mmflags.h:#elif defined(CONFIG_PARISC) ||
defined(CONFIG_METAG) || defined(CONFIG_IA64)
so there is little risk.

I'm happy to put v2 in linux-next now (only patch 4 has changed, I just
sent an updated version), and send you a pull request early next week so
you can take it from there. The patches can't be directly applied with
git-am anyway thanks to the -D option to make them more concise.
Sound okay?
Thanks
James

As discussed, here is a tagged branch to remove arch/metag and dependent
drivers. Its basically v2 with some acks added.

Remove metag architecture
These patches remove the metag architecture and tightly dependent
drivers from the kernel. With the 4.16 kernel the ancient gcc 4.2.4
based metag toolchain we have been using is hitting compiler bugs, so
now seems a good time to drop it altogether.

I've pulled it into my asm-generic tree now, which is also part of linux-next,
and followed up with patches removing frv, m32r, score, unicore32
