STK5200 pci_enable_device problem

[Mustafa Cayir]

Hi ,
i use 2.4.25 kernel and eldk 3.1.1 on TQM5200 board. i tried denx 2.6.19 kernel to port on TQM5200 but i couldn't.
Did you port 2.6 kernel on TQM5200? Did pci device start working succesfully after porting 2.6 kernel to TQM5200 board.

Which ELDK and kernel do you use? I had the same problem on this board 
with a PLX9054 based PCI card on a 2.4.25 kernel. I switched to the 2.6 
kernel and the 4.1 ELDK and the card was scanned correctly.
But keep in mind that the linux PLX drivers do not work out of the box 
with a big endian platform like the MPC5200. Although there is a 
BIG_ENDIAN flag in the makefiles there are still some places left in the 
driver code which have to be patched (the parts with int64 adresses).
It's not so easy to compile the PLX drivers on the 4.1 ELDK because of 
missing headers in the ppc architecture. I managed to build the drivers 
for the 2.6.19 kernel and I was able to work with the card except the 
DMA routines (still working on this issue).

Hope this helps. Bye,
