Subject: [PATCH] config: introduce an INTEL_MID configuration

From: Alan Cox <alan@...ux.intel.com>

We need to carve up the configuration between

- MID general
- Moorestown specific
- Medfield specific
- Future devices

As a base point create an INTEL_MID configuration property. We make the existing
MRST configuration a sub-option. This means that the rest of the kernel config
can still use X86_MRST checks without anything going backwards.

After this is merged future patches will tidy up which devices are MID and
which are X86_MRST, as well as add options for Medfield.
