[linux-yocto] [PULL REQUEST] mei storage proxy device for bxt

[Winkler, Tomas]

Hi Bruce
Here are the patches for mei storage proxy device (SPD) for bxt-rebase.
SPD allows BXT MEI device to store its data on RPMB partition and also EFI to store the EFI variables.
This is currently purely BXT feature and not yet appeared in upstream, except the EFI interruptible patches, that will
need additional work (links to the mailing list are in the commit messages), but the solution is in working condition and is required for the product.


The following changes since commit 58015fa29eb2107c101bd1c2957af08380973d45:

  Merge branch 'standard/intel/base' into standard/intel/bxt-rebase (2016-07-24 23:21:27 -0400)
