hi all,
We are using a customised board which is based on
the reference design of lite5200B. But our board is customised by adding
a PCI-PCI Bridge on the primary bus. On the secondary bus we have added
a DSP(DM642) along with 2 PCI slots, which are routed through
bridge (PCI2250) to MPC5200B.
As far as software is concerned we are using "mpc5200_lite_K26-BSP-b30"
BSP downloaded from freescale's website for lite5200B. This BSP has a
u-boot-1.1.3 and linux kernel-2.6.11.7. As far as u-boot is concerned
the PCI devices are allocated and assigned with proper resources (BAR's)
which come under the range for Mem region(40000000 - 4fffffff) and I/O
region (50000000 - 50ffffff). But during the boot process of linux we
are getting the following errors:
****************************************************************************
***
PCI: Probing PCI hardware
PCI: Cannot allocate resource region 1 of PCI bridge 1
PCI: bridge 1 resource 1 moved to 4ff00000..4fffffff
PCI: Cannot allocate resource region 2 of PCI bridge 1
PCI: bridge 1 resource 2 moved to 4fe00000..4fefffff
PCI: Failed to allocate mem resource #0: 400000 @ 50000000 for
0000:01:08.0
PCI: Failed to allocate mem resource #1: 800000 @ 50000000 for
0000:01:08.0
PCI: Failed to allocate I/O resource #2: 10 @ 1000 for 0000:01:08.0
****************************************************************************
****
where 0000:01:08.0 is the dev function address for DM642(DSP).
I'm stuck up with this problem since long time. Plz help me in giving
some
pointers
for overcoming this problem as i'm a newbie to linux-pci. Any patches
for
the kernel
2.6.11.7 which can resolve the above problem would be of great help.
Thanks and regards,
Ramprasad
