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

i2c: img-scb: Drop METAG dependency (2018-02-26 14:58:09 +0000)
----------------------------------------------------------------
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
