Hi all,
I'm trying to use VPU code driver on iMX51 with kernel 3.18, following 
these steps:
- disabled DVI interface
- enabled LCD interface
- configured and enabled VPU
- copied iMX51 vpu firmware without header and renamed 
v4l-coda7541-imx53.bin in /lib/firmware

Attached you can find the patch and the defconfig I used.

The boot process hangs after loading the firmware at the first attempt 
of writing in VPU address space in the function coda_write of file 
driver/media/platform/coda/coda-common.c

Is there anything preventing the coda driver to work with iMX51?
Could anyone provide any suggestion on how investigate the problem?

Thanks
Regards
Pierluigi
