The MPC837x PCIE controller`s configure address bit field is uniqe:

Initial the MPC837x PCIE controller.
Note that configue address bit field is not compatible with PCIE spec 10a.
Just map first 16M pci configure space which corresponding to a bus configure
space at boot.

Yes. According to the PCI spec, a PCI device can request multi MSI
interrupts and require that interrupts are consecutive.
But it is ok if only allocate one to it.
Anyway, the hwirq should be allocated from bitmap instead of increment
by hand.
I will correct this and resend the patch.

1.Change the device node to pcie

3.Rearrange the codes

Hi Michael,

Level ? Are you sure ? MSIs are by definition edge
