To: linuxppc-dev; +Cc: John Rigby
Modify mpc83xx_add_bridge to get config space register base address from the device
tree instead of immr + hardcoded offset.
83xx pci nodes have this change:
register properties now contain two address length tuples:
First is the pci bridge register base, this has always been there.
Second is the config base, this is new.
This is documented in Documentation/powerpc/dts-bindings/fsl/83xx-512x-pci.txt
The changes accomplish these things:
mpc83xx_add_bridge no longer needs to call get_immrbase
it uses hard coded addresses if the second register value is missing

+* Freescale 83xx and 512x PCI bridges
+
+Freescale 83xx and 512x SOCs include the same pci bridge core.

+83xx/512x specific notes:
+- reg: should contain two address length tuples
+ The first is for the internal pci bridge registers
+ The second is for the pci config space access registers

* [PATCH 5121 pci rev2 3/3] powerpc: pci: 5121: Hide pci bridge.

From: John Rigby @ 2008-08-13 19:06 UTC (permalink / raw)
To: linuxppc-dev; +Cc: John Rigby
The class of the MPC5121 pci host bridge is PCI_CLASS_BRIDGE_OTHER
while other freescale host bridges have class set to
PCI_CLASS_PROCESSOR_POWERPC.
This patch makes fixup_hide_host_resource_fsl match
PCI_CLASS_BRIDGE_OTHER in addition to PCI_CLASS_PROCESSOR_POWERPC.
