Well this is more or less just finalizes what is fact for quite a while now. Any
new patches are made against the Lucid version and if at all it requires poking
people hardly to find out what to do about the Karmic version. It only is a pita
to drag along with every security update.
No one tests Karmic or if people need to completely replace installations on
their boards, causing more lag until a test could be done.

Yes, testing one of the security updates for fsl-imx51 on Lucid caused several
boards to be hard bricked. There was a fix for Lucid but this cannot be applied
to Karmic as the patches on top of 2.6.31 are too different.
I had been asking about Karmic for a long time and I never got feedback. I have
not done any security updates for Karmic fsl-imx51 since then as I could not be
sure the Karmic version might not brick boards and nobody cared.

So I just officially declared that corpse that is called fsl-imx51 in Karmic
dead. It has been rotting long enough now. Surely David could tell me otherwise
but then we need a plan an some man power on the Arm side to bring this into
shape. I cannot honestly call the current state of the repo supported without
getting red and growing a long nose.
