Regarding Angelo's post, is related to:
http://www.mail-archive.com/linuxppc-dev@ozlabs.org/msg21109.html:
(USB on ARCH=PPC works on ARCH=powerpc does not).
and
http://www.nabble.com/USB-on-lite5200-does-not-work.-td20601948.html
(my previous post)
Some NEWS:
we are using now a more recent kernel:
Linux-2.6.26
On our HW:
port_config = 0x0C712E66;
difference between lite5200b.dts and that one for our HW:
========================================================
...
memory {
device_type = "memory";
reg = <0x00000000 0x08000000>; // 128MB
};
...
// rtc at 800 { // Real time clock
// compatible = "fsl,mpc5200b-rtc","fsl,mpc5200-rtc";
// device_type = "rtc";
// reg = <0x800 0x100>;
// interrupts = <1 5 0 1 6 0>;
// interrupt-parent = <&mpc5200_pic>;
// };
...
// PSC4 in uart mode example
serial at 2600 { // PSC4
device_type = "serial";
compatible = "fsl,mpc5200b-psc-uart","fsl,mpc5200-psc-uart";
cell-index = <3>;
port-number = <3>;
reg = <0x2600 0x100>;
interrupts = <2 11 0>;
interrupt-parent = <&mpc5200_pic>;
};
...
// ethernet at 3000 {
// device_type = "network";
// compatible = "fsl,mpc5200b-fec","fsl,mpc5200-fec";
// reg = <0x3000 0x400>;
// local-mac-address = [ 00 00 00 00 00 00 ];
// interrupts = <2 5 0>;
// interrupt-parent = <&mpc5200_pic>;
// phy-handle = <&phy0>;
// };
...
// chosen {
// linux,stdout-path = "/soc5200 at f0000000/serial at 2600";
// };
========================================================
We have got in any case the same problem:
some logs:

========================================================
we were thinking to some problem like:
http://www.nabble.com/USB-support-on-mpc5200-broken-td19658810.html
or
http://www.nabble.com/MPC5200-PCI-interrupt-routing-p19608472.html
We are also thinking about the fact that from .config for PPC we have:
========================================================
PCI support (PCI) [Y/n/?] (NEW) n
Freescale MPC52xx SoC internal IDE (PATA_MPC52xx) [N/m/y/?] (NEW) n
Freescale MPC52xx family PSC serial support (SERIAL_MPC52xx) [N/m/y/?] (NEW) y
Console on a Freescale MPC52xx family PSC serial port (SERIAL_MPC52xx_CONSOLE) [N/y/?] (NEW) y
Freescale MPC52xx family PSC serial port baud (SERIAL_MPC52xx_CONSOLE_BAUD) [9600] (NEW) 9600
OHCI support for on-chip PPC USB controller (USB_OHCI_HCD_PPC_SOC) [Y/n/?] (NEW) y
OHCI support for PCI-bus USB controllers (USB_OHCI_HCD_PCI) [Y/n/?] (NEW) y
Include xmon kernel debugger (XMON) [N/y/?] (NEW) n
Support for early boot texts over serial port (SERIAL_TEXT_DEBUG) [N/y] (NEW) y
========================================================
and for PowerPC we have PCI support on .config and on *.dts but with any PCI modification respects node on lite5200.dts (some interrupt ?)
Have you got any ideas?
Thanks a lot J

Update to the latest kernel (2.6.27+) - there has been lots
of work on the MPC5200 in the past three years (that's how
old 2.6.21 is!)
