No. Its with a new platform I'm currently working on (MediaTek
MT7688 MIPS) - custom board. The platform and board port will be
posted in a few days / weeks (once its ready).

AFAICT its not generic. The SPI NAND seems to be working for Miquel
and its a new infrastructure. So chances for breaking an existing
board / platform are pretty low. By pulling this patchset now, we
enable the possibility for implementing and testing it on other
platforms sooner. Tom also seems to be willing to do so.

Thanks,
Stefan
