<<pci_boot.pdf>> Kumar,
We do not support or care about VIA IDE controller. I have enabled the
DEBUG flag and attached the debug messages during boot. This is for
8541E.
Regards,
Bizhan

Do you need support for the VIA IDE controller? I'm not sure if that is
causing you issues.
Also, can you try enabling DEBUG in arch/ppc/kernel/pci.c and send a
boot log. I'm trying to figure out what is causing the resource
conflict. It appears that the memory resource is reasonable, but there
could be possible conflict on the IO resource side.
Also, if you can send logs of the same thing from the working 8540 ADS
that would be helpful.

Hi Kumar,
I am using Linux 2.6.11, u-boot 1.1.2.
I see failure in pci_enable_device with message:
"PCI: Device 0000:02:01.0 not available because of resource
collisions"
I have attached three files:
lspci_output.txt: out put of the "lspci -v"
proc_pci.txt: output of the "cat /proc/pci"
u-boot.txt: output of the "pci command at u-boot"
Any help greatly appreciated,
Bizhan

Bizhan,
A few questions:
1. what kernel version are you using on these boards:
2. can you do an lspci -v on the boards

Hi All,
I am using two evaluation board from freescale, 8540ADS and MPC8541.
The same PCI driver is being compiled and loaded on both platforms.
The same PCI driver (developed by me) for DSP board compiled and
loaded on both platforms.
When I type: "insmod C6415.ko" on 8541 board, I get the following
error:
"PCI: Device 0000:02:01.0 not available because of resource
collisions"
This messages is because of the execution of the generic PCI Linux
command:
"pci_enable_device(pdev)"
The same API has no problem on 8540ADS.

Any idea why the insmod fails on one board and not on the other one?
Many thanks in advance,

It would be extremely helpful to get the output from the work MPC8540
for lspci and cat /proc/pci.
Also, I forget if 2.6.11 has CDS VIA support, but if it does you can
try disabling it by commenting out the calls to:
mpc85xx_cds_enable_via() & mpc85xx_cds_fixup_via() in arch/ppc/syslib/
ppc85xx_setup.c and see what happens.
