Hello everybody,
meanwhile I've fixed one more issue in mpc512x_dma driver.
Any comments? Anybody interrested in this driver? Piotr?
Still unsure how to deal with bitfield structures in IO space...
Currently I am not able to deal

Ok so you'll have to make up a workaround in prom_init that looks for
OHCI's in the device-tree and disable them.
Check if the OHCI node has some existing f-code words you can use for
that with dev /path-to-ohci words in OF for example. If not, you may
need

In the installed system, run 'lspci | grep -i usb', this gives the pci

Hi,

Freescales p2020.

Since then, the silence has been deafening.
My assumption now is that this is not ever getting fixed. I'm certainly not
able to fix it. I'm not a even kernel programmer! I got far enough to
diagnose the cause just with the add more printk's and boot it again
technique. Hundreds of reboots

You look for compatible usb-ohci.
But this doesn't help you. You do not know yet if the
problem happens for all usb-ohci; for example, it could be
that you have the console output

There is no compatible there. I can probably use class-code since the
parent is a PCI bus.
But this doesn't

We are not.

I see. Excuse me for disturbing you then.
Guys, anybody can review/test/pull these patches?

Hi all,
I'm trying to bring up a RapidIO on my p2020 on v2.6.36-rc7. I'm
running into an issue when the host tries to enumerate the agent
devices, and fails miserably. The rio driver does a
fsl_rio_config_read with a destid of 255, after which it hangs, until
I get a timeout exception (Handled
