[RFC PATCH 0/2] Support for picoxcell OTP memory

[Jamie Iles]

This patch series adds support for the OTP memory in picoxcell devices
which can be used for the first-stage bootloaders, cryptographic keys
and any other per-device information.  The first patch implements a
fairly generic OTP layer that handles the userspace interface and device
registration and abstracts the backend detail of how to actually read
and write the OTP to support different backends.

The second patch implements support for the OTP PC3X3 family of devices
which has 16KB of OTP.

Greg, I'm not sure if what I've done here is the best way to interface
with the driver model but I'm open to changes!
