From 70ed869ea5f6b1d13d7b140c83ec0dcd8a127ddc Mon Sep 17 00:00:00 2001 From: Vivek Mahajan Date: Tue, 27 Oct 2009 12:18:55 +0530 Subject: 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 Signed-off-by: Kumar Gala --- include/asm-ppc/fsl_pci.h | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'include/asm-ppc') diff --git a/include/asm-ppc/fsl_pci.h b/include/asm-ppc/fsl_pci.h index 2790da7ed..6b0c89bd3 100644 --- a/include/asm-ppc/fsl_pci.h +++ b/include/asm-ppc/fsl_pci.h @@ -62,6 +62,7 @@ typedef struct pci_inbound_window { #define PIWAR_LOCAL 0x00f00000 #define PIWAR_READ_SNOOP 0x00050000 #define PIWAR_WRITE_SNOOP 0x00005000 +#define PIWAR_IWS_4K 0x0000000b u32 res2[3]; } pit_t; @@ -171,7 +172,7 @@ struct fsl_pci_info { }; int fsl_pci_init_port(struct fsl_pci_info *pci_info, - struct pci_controller *hose, int busno); + struct pci_controller *hose, int busno, int pcie_ep); #define SET_STD_PCI_INFO(x, num) \ { \ -- cgit v1.2.3
