There is at the moment no video driver for the MX.51 on the u-boot
mainline. I am not sure about the Freescale's BSP, but as far as I know
there is no support for the MX51's IPUv3. But I could be wrong, ask
Freescale for confirm.

However, on this ML you can find issues regarding the u-boot mainline.
The "babbage" board is renamed on u-boot mainline as "imx51evk", because
this is the name you find now for this board on the Freescale's website.
If you have developed something that is not yet provided, feel free to
send patches and to contribute to the project.

Related to the MX.51 framebuffer support, I am working on the same
issue. I have ported the Freescale's Linux driver to u-boot, and at
least it is working, but I am not yet ready to send patches. I am still
cleaning up code and reducing functionalities, as the IPU supports much
more as only a framebuffer. Of course, providing patches is on my TODO
list, and I hope I can send them soon...

I think there is no support for i.MX51's framebuffer at all, as well as
in u-boot mainline....;-(
