cover Add Time-Limited-Kernel Layer to meta-intel

Tom, Darren:

This adds Bruce's changes to allow for a time limited kernel, the default is set for 10 days.

This layer will only be added to the meta-intel BSP on the Auto-builder.

PATCH 1/1 meta-tlk: initial creation

From: Bruce Ashfield <[email protected]>

Call this layer whatever you want, but when enabled it turns on BSP configuration items specific to autobuild/official binary images. Once this is enabled the uptime of any BSP will be limted to the value in the .cfg. It is currently at 2 minutes as an example, but it should be extended to a number of days going forward.

meta-tlk: Rename and changed to 10 day limit

I presume we need a linux-yocto-rt_3.0.bbappend as well?

Are we building and delivering RT images for the release? If not then there is no need.

Given the increased interest in preempt-rt support, I think it would make sense to do so. It certainly adds a further burden to the release process.
