 This document is a guide to use the PCI Endpoint Framework in order to create
 endpoint controller driver, endpoint function driver, and using configfs
 interface to bind the function driver to the controller driver.

 The PCI Endpoint Core layer comprises 3 components: the Endpoint Controller
 library, the Endpoint Function library, and the configfs layer to bind the
 endpoint function with the endpoint controller.
 
 2.1 PCI Endpoint Controller(EPC) Library
+----------------------------------------
 
 The EPC library provides APIs to be used by the controller that can operate
 in endpoint mode. It also provides APIs to be used by function driver/library
 in order to implement a particular endpoint function.

 by the PCI controller driver.

    The PCI controller driver can destroy the EPC device created by either

    In order to notify all the function devices that the EPC device to which
    they are linked has established a link with the host, the PCI controller
    driver should invoke pci_epc_linkup().
 
-*) pci_epc_mem_init()

    The PCI endpoint function driver should use pci_epc_write_header() to
    write the standard configuration header to the endpoint controller.
 
-*) pci_epc_set_bar()
+* pci_epc_set_bar()
 
    The PCI endpoint function driver should use pci_epc_set_bar() to configure
    the Base Address Register in order for the host to assign PCI addr space.
    Register space of the function driver is usually configured
    using this API.
 
-*) pci_epc_clear_bar()

    The PCI endpoint function driver should use pci_epc_clear_bar() to reset
    the BAR.
 
-*) pci_epc_raise_irq()
+* pci_epc_raise_irq()
 
    The PCI endpoint function driver should use pci_epc_raise_irq() to raise
    Legacy Interrupt, MSI or MSI-X Interrupt.
 
-*) pci_epc_mem_alloc_addr()
+* pci_epc_mem_alloc_addr()
 
    The PCI endpoint function driver should use pci_epc_mem_alloc_addr(), to
    allocate memory address from EPC addr space which is required to access
    RC's buffer
 
-*) pci_epc_mem_free_addr()
+* pci_epc_mem_free_addr()
 
    The PCI endpoint function driver should use pci_epc_mem_free_addr() to
    free the memory space allocated using pci_epc_mem_alloc_addr().
 
 2.1.3 Other APIs
+~~~~~~~~~~~~~~~~
 
 There are other APIs provided by the EPC library. These are used for binding
 the EPF device with EPC device. pci-ep-cfs.c can be used as reference for
 using these APIs.

    Get a reference to the PCI endpoint controller based on the device name of
    the controller.
 
-*) pci_epc_put()

    Release the reference to the PCI endpoint controller obtained using
    pci_epc_get()
 
-*) pci_epc_add_epf()
+* pci_epc_add_epf()
 
    Add a PCI endpoint function to a PCI endpoint controller. A PCIe device
    can have up to 8 functions according to the specification.
 
-*) pci_epc_remove_epf()
+* pci_epc_remove_epf()
 
    Remove the PCI endpoint function from PCI endpoint controller.
 
-*) pci_epc_start()

    The PCI endpoint function driver should invoke pci_epc_start() once it
    has configured the endpoint function and wants to start the PCI link.
 
-*) pci_epc_stop()
+* pci_epc_stop()
 
    The PCI endpoint function driver should invoke pci_epc_stop() to stop
    the PCI LINK.
 
 2.2 PCI Endpoint Function(EPF) Library
