[Buildroot] Freescale specific kernel header to compile imx-lib

[Alexandre Schnegg <alexandre.schnegg@gmail.com>]

Dear Thomas,

I'm not familiar with the mailing list usage so if I make another mistake please tell me.

By the way, I have got an answer from Armadeus :

" current (recent) gstreamer-fsl-plugins only works with recent imx-lib packages which doesn't seems to work on i.MX27 anymore... (tested on APF51 only)"

They have a home made way to use the hardware acceleration, I will test it.

Thank you for your help.
Alexandre Schnegg

Dear Alexandre Schnegg,

Can you please reply to the Buildroot mailing list (possibly with me in
Cc) and not just to me directly? Whenever I provide free support, I'd like it to be public and archived in the mailing list.

Thanks!

Thomas
