From b6ccd2c9dee758a70e761403a41e60c31a1cfcec Mon Sep 17 00:00:00 2001 From: Prabhakar Kushwaha Date: Fri, 4 Feb 2011 09:00:43 +0530 Subject: fsl_pci: Add support for FSL PCIe controllers v2.x FSL PCIe controller v2.1: - New MSI inbound window - Same Inbound windows address as PCIe controller v1.x Added new pit_t member(pmit) to struct ccsr_pci for MSI inbound window FSL PCIe controller v2.2 and v2.3: - Different addresses for PCIe inbound window 3,2,1 - Exposed PCIe inbound window 0 - New PCIe interrupt status register Added new Interrupt Status register to struct ccsr_pci & updated pit_t array size to reflect the 4 inbound windows. To maintain backward compatiblilty, on V2.2 or greater controllers we start with inbound window 1 and leave inbound 0 with its default value (which maps to CCSRBAR).
