From a4aafcc990c12816cfd4644e5c003d8556b6236b Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Wed, 15 Dec 2010 14:21:41 -0600 Subject: powerpc/fsl-pci: Add generic code to setup PCIe controllers Since all the PCIe controllers are connected over SERDES on the SoCs we can utilize is_serdes_configured() to determine if a controller is enabled. After which we can setup the ATMUs and LAWs for the controller in a common fashion and allow board code to specify what the controller is connected to for reporting reasons. We also provide a per controller (rather than all) for some systems that may have special requirements. Finally, we refactor the code used by the P1022DS to utilize the new generic code.
