* ppc/85xx/pci: fsl_pci_init: pcie agent mode supportVivek Mahajan2009-10-27-2/+16
| | | | | | | | | | | | | | | 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>
* ppc/85xx: Clean up p1_p2_rdb PCI setupKumar Gala2009-09-24-1/+1
| | | | | | | | General code cleanup to use in/out IO accessors as well as making the code that prints out info sane between board and generic fsl pci code. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* driver/fsl_pci: Add fsl_pci_init_port function to initialize a PCI controllerPoonam Aggrwal2009-08-28-0/+44
| | | | | | | | | fsl_pci_init_port can be called from board specific PCI initialization routines to setup the PCI (or PCIe) controller. This will reduce code redundancy in most of the 85xx/86xx FSL board ports that setup PCI.

* pci/fsl_pci_init: Rework PCI ATMU setup to handle >4G of memoryKumar Gala2009-08-28-63/+162
| | | | | | | | | | | | | | | | | | | | | | | | | | | The old PCI ATMU setup code would just mimic the PCI regions into the ATMU registers. For simple memory maps in which all memory, MMIO, etc space fit into 4G this works ok. However there are issues with we have >4G of memory as we know can't access all of memory and we need to ensure that PCICSRBAR (PEXCSRBAR on PCIe) isn't overlapping with anything since we can't turn it off. We first setup outbound windows based on what the board code setup in the pci regions for MMIO and IO access. Next we place PCICSRBAR below the MMIO window. After which we try to setup the inbound windows to map as much of memory as possible. On PCIe based controllers we are able to overmap the ATMU setup since RX & TX links are separate but report the proper amount of inbound address space to the region tracking to ensure there is no overlap. On PCI based controllers we use as many inbound windows as available to map as much of the memory as possible. Additionally we changed all the CCSR register access to use proper IO accessor functions. Also had to add CONFIG_SYS_CCSRBAR_PHYS to some 86xx platforms that didn't have it defined.

* pci/fsl_pci_init: Use PCIe capability to determine if controller is PCIeKumar Gala2009-08-28-19/+13
| | | | | | | | Change the code to use the PCIe capabilities register to determine if we are a PCIe controller or not. Additionally cleaned up some white space and formatting in the file. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* pci/fsl_pci_init: Fold fsl_pci_setup_inbound_windows into fsl_pci_initKumar Gala2009-08-28-1/+7
| | | | | | | | Every platform that calls fsl_pci_init calls fsl_pci_setup_inbound_windows before it calls fsl_pci_init. There isn't any reason to just call it from fsl_pci_init and simplify things a bit. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* pci: Rename PCI_REGION_MEMORY to PCI_REGION_SYS_MEMORY for clarityKumar Gala2009-02-07-5/+5
| | | | | | | | | | The PCI_REGION_MEMORY and PCI_REGION_MEM are a bit to similar and can be confusing when reading the code. Rename PCI_REGION_MEMORY to PCI_REGION_SYS_MEMORY to clarify its used for system memory mapping purposes. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* drivers/fsl_pci_init: Fix inbound window mapping bugBecky Bruce2008-12-03-1/+1
| | | | | | | | | | | | | The current code will cause the creation of a 4GB window starting at 0 if we have more than 4GB of RAM installed, which overlaps with PCI_MEM space and causes pci_bus_to_phys() to return erroneous information. Limit the size to 4GB - 1; which causes the code to create one 2GB and one 1GB window instead.
