  It's hard to know for sure. Like most SoC vendors, Freescale assume 
you'll just use _their_ kernel, _their_ toolchain, _their_ binary 
libraries and even _their_ LTIB (though it seems Freescale is becoming 
more open about this).

  Now, regarding the kernel it's pretty easy: upstream support for i.MX6 
is limited to UART, SD and USB so you're bound to the Freescale kernel if 
you want to use any graphics at all. And the Freescale kernel contains 
the galcore module needed for accessing the vivante GPU.

  There is also firmware for the VPU in the imx-firmware package, but I 
think that is only needed for the H.264 etc. codecs.
