PandaBoard in AOSP master: fixed

[Jean-Baptiste Queru]

We've fixed the issue with PandaBoard in the AOSP master. It works
with the binaries that are marked as IMM76D.

Credit goes to Texas Instruments for investigating the root issue and
implementing the fix.

Enjoy :)

That's my mistake. I meant IMM76I. Sorry about that.

-Indeed, there's no ducati binary available for AOSP (for PandaBoard
or for Galaxy Nexus), so we don't have any media acceleration
available.

-The widevine stuff is a mess, I can't describe it in any better way.

On the ducati side, that's purely a licensing issue, i.e. all non-technical.

The widevine stuff ends up on all retail devices, in different forms.
One of the problem is that it's device-specific but leaks into the
common code, and when using that common code on devices that don't
support it (like PandaBoard) things tend to fall apart. Contributions
welcome to make things work better when there's no implementation of
the device-specific libraries in question.

There was at least some of it in ICS, as I remember that it was
causing me some pain for Galaxy Nexus.

As far as I know there's on DRM implementation for PandaBoard.

I've just merged a change that might actually improve audio, but I
don't expect that'll get you as far as getting DRM working.
