Hi Andre and others,
</pre>
<blockquote type="cite">
<pre wrap="">currently I'm trying to bring up a mpc8343 based system.
Latest u-boot v1.3.2 is running fine.
The MPC8343 has a single 32-Bit PCI Bus running at 66MHz.
Connected are a FPGA (IDSEL 11 + IRQ0) and a miniPCI Slot (IDSEL12 +
IRQ1).
Unfortunately the kernel panics during/after PCI setup.

Not sure if this is related. But i got strange problems with PCI after
the patch "Add CONFIG_PCI_SKIP_HOST_BRIDGE config option"
(55774b512fdf63c..) was added.
My symptoms where missed interrupts on sata dma in Linux. U-boot where
however fine. Adding the above config solved my problems. Not really
sure why i experienced this. We have no PCI bridge on our board.

Tor,<br>
<br>
thanks for your reply.<br>
<br>
I'm also not sure if it's a PCI issue anymore ...<br>
<br>
Kernel config has been reduced to a minimum : no PCI, no netwoking,
i2c, spi ...<br>
dts has been reduced to the CPU, soc and ipic.<br>
<br>
U-Boot fills out dtb correctly - as far as I can see.<br>
<br>
Kernel crashes on various "of_" functions.<br>
<br>
There's also strange messages :<br>
WARNING: Estimating decrementer frequency (not found)<br>
WARNING: Estimating processor frequency (not found)<br>
<br>
They're coming from "generic_calibrate_decr()" in kernel/time.c.<br>
<br>
Looks like there something basically wrong with my dtb
location/processing, since the "timebase-frequency" is present and
valid :<br>
<br>
       cpus {<br>
               #address-cells = <0x00000001>;<br>
               #size-cells = <0x00000000>;<br>
               PowerPC,8343@0 {<br>
                       device_type = "cpu";<br>
                       reg = <0x00000000>;<br>
                       d-cache-line-size = <0x00000020>;<br>
                       i-cache-line-size = <0x00000020>;<br>
                       d-cache-size = <0x00008000>;<br>
                       i-cache-size = <0x00008000>;<br>
                       timebase-frequency = <0x03f940aa>;<br>
                       bus-frequency = <0x0fe502a8>;<br>
                       clock-frequency = <0x17d783fc>;<br>
               };<br>
       };<br>
<br>
<br>
Any hints ?<br>
<br>
<br>
regards,<br>
Andre<br>
