MPC8315E PCIe memory configuration

linjiepan — Mon, 04 Jul 2016 03:00:17 GMT

On physical hardware，PCIe 1 connects with PCI device（BCM56134）.

When during scanning pci 1 bus,why It can't detect bcm56134?

It print like this：

In fact,Should be printed like this:

How to set the PCI configuration space, MEM space and I/O space?

and Which register are need to set?

Such these Macro definitions,how to set ?

CONFIG_SYS_PCIE1_BASE、CONFIG_SYS_PCIE1_MEM_BASE、CONFIG_SYS_PCIE1_MEM_PHYS、CONFIG_SYS_PCIE1_MEM_SIZE?

CONFIG_SYS_PCIE1_CFG_BASE、CONFIG_SYS_PCIE1_CFG_SIZE?

CONFIG_SYS_PCIE1_IO_BASE、CONFIG_SYS_PCIE1_IO_PHYS、CONFIG_SYS_PCIE1_IO_SIZE?
