understood, thanks for the details.

One last thing while at it : last year, Linaro's FSL team told me they
were about to release an updated kernel for i.MX53 (with updated GPU
closed source libraries & drivers as they had sources for that under
NDA - the userspace binaries are packed into an hwpack named something
like hwpack_linaro-lt-mx5_YYYYMMDD_armel_supported.tar.gz ).
In the end that was never made public but from what I understood they
delivered the sources to Freescale : are there any plan to release
these versions (even if that's not officialy supported by Freescale SDK
and marked as experimental) to meta-fsl-arm so that we can update i.MX53
based designs to more recent kernel than 2.6.35 and still use the GPU ?

Thanks,
Eric
