kernel dmesg log & NVDA,BMP FCODE ROM

Hi,

When running a Powermac 11.2, (G5 Quad - powerpc64) with a Quadro FX4500
(NV47), previous kernels had no issue extracting the FCODE ROM / DCB block via
the OpenFirmware device tree.
Last vanilla kernel that i have compiled that seemed to work fine was kernel
3.18.16.
Normally, it will find the "BIT SIGNATURE" via OpenFirmware method.

However, when compiling a newer vanilla kernel 4.1.2, nouveau seems to have an
issue reading the FCODE ROM / DCB block / from the OpenFirmware device tree.
Also, interestingly, this time around it attempts to use the PROM method and
attempts to find the "BIT SIGNATURE" via this method.
Apparently it found a signature, but looks like garbage and seems like it cant
extract the DCB BLOCK.

As instructed, i have attached a dmesg.log along with a dump of the NVDA,BMP
image out of the following folder:
/sys/firmware/devicetree/base/pci@0,f0000000/NVDA,Parent@0/.

Not sure if this is correct, but i have passed the following nouveau module
options as i understood:

options nouveau config="NvMSI=0,debug=debug,VBIOS=trace"

I have placed the kernel dmesg log along with the NVDA,BMP dump in the attached
nouveau_powerpc64_pmac11.2.tar.xz archive.

Please let me know if there is any more info required.

Thanks for your help!

Best Regards,
Peter
