Subject: [PATCH 017/116] PCI: microchip: Add bridge_addr field to struct
|
|
mc_pcie
|
|
|
|
For bridge address base is common PLDA field, Add this to struct mc_pcie
|
|
first.
|
|
|
|
INTx and MSI codes interrupts codes will get the bridge base address from
|
|
port->bridge_addr. These codes will be changed to common codes.
|
|
axi_base_addr is Microchip its own data.
