Kernel PKGs CI: Enabling other LTs

Registered by Ricardo Salveti

Currently we have both linux-linaro and lt-omap enabled at CI, and generating packages automatically at the Staging PPA.

This blueprint is to make sure we also enable the same logic for other LTs, such as Samsung, Freescale and STE, so we can always have the latest and greatest kernel available for people to test and try.

[rsalveti, Jan 5, 2011] All LTs should be at 3.1 already, but 3.2 should probably be available quite soon, so maybe it'd be good to have both 3.1 and 3.2 enabled for the LT that supports both. We should push the packaging/config tree at a common place also, so we can also request help from the LT while maintaining the config set for the kernel.
[jcrigby, Jan 11 2012] The existing script for last cycle works for TI LT 3.1 kernel. Not sure if there is a TI LT candidate 3.2 kernel. Also adding some WI's for fixing some known issues in scripts.
[rsalveti, Jan 11, 2012] For now we'll stick with TI LT 3.1 series, because it's the only one with support for video decode, but would also be nice to enable a build for TI LT 3.2, for people who want to try the latest kernel available from the LT.
[dzin, Jan 20, 2012] Is there a Roadmap ID associated with this?
[rsalveti, Jan 20, 2012] No, there's no roadmap for it atm.
[jcrigby, Jan 24, 2012]Still working on adding more LT kernel both 3.1 and 3.2. Everything else is done.
[jcrigby, Jan 25, 2012] All jobs created on and all recipes created on lp. Samsung (origen) and Snowball (ux500) are 3.2 only as the LTs indicated that all work has moved on to that release.
[rsalveti, Jan 25, 2012] Thanks! :-)

Headline: Landing Team packaged LEB kernels for Freescale, Samsung and Snowball are now generated in a CI loop.
Acceptance: Jobs on automatically create packaged Ubuntu kernels that are built using launchpad recipes resulting in working linux-image debian packages in staging overlay ppa.
