Subject: MPC8548 PCIe / PCI support with BSP MPC8548CDS 02/24/2006
Hi,
I am currently working on a MPC8548-based development system.
Linux kernel version is 2.6.11 with patches delivered from
Freescale (BSP MPC8548CDS 02/24/2006).
Kernel configuration contains a warning message for CONFIG_PEX:
This requires hardware modification to work correctly if
your CPU version 2.0 and will break the PCI bus. [...]
I was wondering whether enabling PCIe makes PCI bus
functionality unusable at all (including kernel functionality
for detecting devices behind a transparent PCI-to-PCI bridge).
The interrupts polarity of MPC8548 PCIe controller is reversed to PCI. That's
an errata of MPC8548.
So you must rework to fix them. You can find the detail from user manual of bsp.
Our setup connects a transparent PLX8516 PCI-to-PCI bridge to
the PCIe port of the MPC8548 daughter board. Behind that
bridge is another PCIe capable device.
MPC8548 is configured to run as PCIe host mode.
When trying to lookup the PCIe devices using lspci I can only
see the PPC itself and the bridge.
However I cannot see the device(s) behind the bridge.
Yes, that's also an errata to MPC8548 PCIe controller.
Trying to apply below patch code:

Is there a publicly available source for patches to the current BSP? Are there any other PCIe-related fixes? It's an add-on PCIe patch. We have tested it on MPC8641, but we have no PCIe-PCI bridge on MPC8548 platform to do more test.

Reg RISC timers in MPC 8260
Hi all

MPC8548 PCIe / PCI support with BSP MPC8548CDS 02/24/2006
Hi, Zhang Wei-r63237 schrieb: It's an add-on PCIe patch. We have tested it on MPC8641, but we have no PCIe-PCI bridge on MPC8548 platform to do more test. So if you verify it, I'll commit it. :) We did the hardware fix described in the BSP user's manual to make PCIe work (according to the manual section 2.1, step 3). I.e. 1) removed R193 and R194 on the carrier card (rev 1.2) 2) removed RN1 on the CPU daughter card 2a) connected pad3 of RN1 to pin3 of U12 (IRQ0) 2b) connected pad2 of RN1 to pin4 of U12 (IRQ1) Does this fix the interrupt polarity problem (as well)? We applied the provided kernel patch as well. IMHO that patch just moves the local PCIe root-complex out-of-space so no detection of that one occurs any more. This is what actually happens when lspci is run. However we still don't see any devices behind the PCIe switch (e.g. a transparent PLX8516). It seems that the enumeration process (traversing through the bus hierarchy) in the kernel is somehow disabled. Bottom line: Only one device accessible at all on the PCIe port. Any further ideas? Thanks, Florian

Using bestcomm in an external module (MPC5200B to be exact)
Yes I know its the work of many people, calling it your was just an abbreviation. The latest ltib isn't based on your latest but then again your latest was never public:). So is your git tree uptodate? If so then I will look at putting together some patches to it. I have an ata update and also an ac97 driver. My goal is to have the best version in the public and ltib just a copy of it.
