Freescale would love to open its GPU etc, however it is licensing the IP from other vendors that Freescale has no right to open source it, yes it would be nice if Freescale can get that part work. Otherwise, Freescale is fairly open on everything it owns and makes.
The Raspberry Pi having a non-closed bootchain, let alone a free driver is a feat of tens of thousands of people pressuring Broadcom, and a few people doing the hard work to free as much of the RPI as they could.
Having to run Raspbian just to boot the board was a dark time!
