These are some small misc clean ups to PPC440 related device models
which is all I have ready for now.
BALATON Zoltan (13):
ppc440: Change ppc460ex_pcie_init() parameter type
ppc440: Add cpu link property to PCIe controller model
ppc440: Add a macro to shorten PCIe controller DCR registration
ppc440: Rename local variable in dcr_read_pcie()
ppc440: Stop using system io region for PCIe buses
sam460ex: Remove address_space_mem local variable
ppc440: Add busnum property to PCIe controller model
ppc440: Remove ppc460ex_pcie_init legacy init function
ppc4xx_pci: Rename QOM type name define
ppc4xx_pci: Add define for ppc4xx-host-bridge type name
ppc440_pcix: Rename QOM type define abd move it to common header
ppc440_pcix: Don't use iomem for regs
ppc440_pcix: Stop using system io region for PCI bus

Change parameter of ppc460ex_pcie_init() from env to cpu to allow
further refactoring.

The PCIe controller model uses PPC DCRs but cannot be modeled with
TYPE_PPC4xx_DCR_DEVICE as it derives from TYPE_PCIE_HOST_BRIDGE. Add a
cpu link property to it similar to other DCR devices to allow
registering DCRs from the device model.

It is more readable to wrap the complex call to ppc_dcr_register in a
macro when needed repeatedly.

Add separate memory regions for the mem and io spaces of the PCIe bus
to avoid different buses using the same system io region.

Some places already use get_system_memory() directly so replace the
remaining uses and drop the local variable.

Instead of guessing controller number from dcrn_base add a property so
the device does not need knowledge about where it is used.

Rename the TYPE_PPC4xx_PCI_HOST_BRIDGE define and its string value to
match each other and other similar types and to avoid confusion with
"ppc4xx-host-bridge" type defined in same file.

move it to common header and use it also in sam460ex to replace hard

The iomem memory region is better used for the PCI IO space but
currently used for registers. Stop using it for that to allow this to
be cleaned up in the next patch.

Use the iomem region for the PCI io space and map it directly from the
board without an intermediate alias that is not really needed.

The parenthesis here would be superfluous as it stands alone in a function
parameter between commas so no matter what you substitue here should not
have an unwanted side effect (unless it has a comma but that's an error
anyway) so maybe this is not needed.

Thanks for the quick review, I'll post a v2 in a few days to wait a bit if

That's way too long so I'd drop bridge from all of these and maybe name
this ppc4xx-pci-host-fn0 or ppc4xx-pci-host-func (there are no other
functions of the bridge so this shows this is the PCI side of it). I'd
still go for shorted defines and not changing the string types too much.
Would that be acceptable?

Unlike the other similar patch this does not reduce the IO space size
because get_system_io() was that size already. I've changed the size below
to use KiB.

Well I noticed because you used it for the 2 other cases, so I'm
just trying to be consistent here. Besides, not using parenthesis
for macro arguments is a bad practice. Problems happen when others
copy code.

But we can't free() it because it has to stay valid as long as
PPC440PCIXState is in use. So it seems to belong there.
