* 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
|
|
|
|
