Hi all, I want to configure my board as a PCI target, its based on mcf548x processor. What are the things to be taken care to configure a board as a PCI agent in u-boot?
My processor can act as a PCI master as well as a target. I don't want master interface at all. I want to make my board as a PCI slave and let it respond to other masters by simply sitting on a PCI bus. I have gone through the u-boot sources and I found that board/freescale/mpc8360emds/pci.c does something similar if CONFIG_PCISLAVE is defined. Its is setting up inbound windows and using pci_setup_indirect(), pci_hose_read_config_word(), pci_hose_write_config_word() functions to make the board a pci slave. I don't really understand the use of these functions, if i am able to read and write PCI config registers(256 bytes) through my internal bus why these are required? As per my understanding I just have to configure the PCI inbound windows and leave the rest to PCI master of the entire system. am I thinking wrong?
