Right - there is a dependency on l2-mtd.git here.

Since they didn't request pull for 3.6, there is quite some stuff
pending in their tree (but I wonder why it isn't already part of
linux-next, so the above error at least shouldn't occur in linux-next).

So we have several alternative options here:

* If it is possible, include l2-mtd.git as a dependency in arm-soc.git
* Merge the following 2 patches as minimal dependency:
You actually only need the two .h files, ignore the patches for yet
non-existing .c mtd driver files in arm-soc.git.
* Defer the above (single) patch in arm-soc until l2-mtd is merged
linux-next or mainline. Maybe l2-mtd.git will appear in linux-next soon,
otherwise we will need to defer the above patch for lpc32xx/core for 3.8?

Sorry for the confusion,
