[PATCH] ppc32: Add support for handling PCI interrupts on MPC834x PCI expansion card
The MPC8349 PIBs system has a expansion board with 6 PCI slots. We needed
to update the IDSEL interrupt mapping for it to work properly. However,
only PCI1 is supported as the first revision of this expansion board
doesn't function properly for PCI2. For the time being we have zero'd out
the entries for the IDSELs related to PCI2. When a functioning expansion
board exists we can fix the table.
