50a4d08e8f mpc83xx: PCI: Fix hard-coded first_busno value
We should use pci_last_busno() in pci_init_bus(), otherwise we'll
erroneously re-use PCI0's first_busno for PCI1 hoses.

NOTE: The patch is untested. All MPC83xx FSL boards I have have
PCI1 in miniPCI form, for which I don't have any cards handy.

But looking in cpu/mpc85xx/pci.c:
...
#ifdef CONFIG_MPC85XX_PCI2
        hose = &pci_hose[1];

        hose->first_busno = pci_hose[0].last_busno + 1;

And considering that we do the same for MPC83xx PCI-E support,
I think this patch is correct.

a5878d4271 mpc83xx: PCI: Fix bus-range fdt fixups for PCI1 controllers
This patch fixes copy-paste issue: pci_hose[0]'s first and last
busnos were used to fixup pci1's nodes.

We don't see this bug triggering only because Linux reenumerate
buses anyway.

ff4e66e93c pci: Rename PCI_REGION_MEMORY to PCI_REGION_SYS_MEMORY for clarity
The PCI_REGION_MEMORY and PCI_REGION_MEM are a bit to similar and
can be confusing when reading the code.

Rename PCI_REGION_MEMORY to PCI_REGION_SYS_MEMORY to clarify its used
for system memory mapping purposes.

75f35209f7 83xx: PCI agent mode fixes for multi-board systems
When running a system with 2 or more MPC8349EMDS boards in PCI agent mode,
the boards will lock up the PCI bus by scanning against each other.

The boards lock against each other by trying to access the PCI bus before
clearing their configuration lock bit. Both boards end up in a loop,
sending and receiving "Target Not Ready" messages forever.

When running in PCI agent mode, the scanning now takes place after the
boards have cleared their configuration lock bit.

Also, add a missing declaration to the mpc83xx.h header file, fixing a
build warning.

4ff9aea9d6 mpc83xx: add PCISLAVE support to 83XX_GENERIC_PCI setup code
This adds a helper function to unlock the PCI configuration bit, so that
any extra PCI setup (such as outbound windows, etc.) can be done after
using the 83XX_GENERIC_PCI code to set up the PCI bus.

5b8bc606c6 mpc83xx: convert to using do_fixup_*()
convert to using simpler mpc85xx style fdt update code; streamline by
eliminating macros OF_SOC, OF_CPU, etc. which allows us to rm
the old school FLAT_TREE code from 83xx (since the sbc8349 was just
converted over to using libfdt).

copy-and-paste it for themselves.  Boards should be converted to use this
