ppc/85xx/pci: fsl_pci_init: pcie agent mode support
Originally written by Jason Jin and Mingkai Hu for mpc8536. When QorIQ based board is configured as a PCIe agent, then unlock/enable inbound PCI configuration cycles and init a 4K inbound memory window; so that a PCIe host can access the PCIe agents SDRAM at address 0x0 * Supported in fsl_pci_init_port() after adding pcie_ep as a param * Revamped copyright in drivers/pci/fsl_pci_init.c * Mods in 85xx based board specific pci init after this change Signed-off-by: Vivek Mahajan <vivek.mahajan@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
