Umm... no. Embedded Plaet and Freescale are two different  companies,
and EP5200 and Lite5200 are two different boards.

Our kernel does not include any support for the EP5200 board.

Please read the documentation that comes with the driver:
ftp://ftp.denx.de/pub/fujitsu/Coral-P/README.html

Note that the driver was  built  and  tested  against  xfree86-4.3.0;
don't  expect  the  binary  to  work  in  a  completely different X11
release. You wil have to rebuild (and eventually  adapt)  the  driver
for your environment.

Feel free to contact me if you need help.

Best regards,

Wolfgang Denk
