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