* drivers/pci: Create pci_map_bar functionBecky Bruce2009-02-10-0/+19
| | | | | | | | It is no longer always true that the pci bus address can be used as the virtual address for pci accesses. pci_map_bar() is created to return the virtual address for a pci region. Signed-off-by: Becky Bruce <beckyb@kernel.crashing.org>
* pci: give preference to non-PCI_REGION_SYS_MEMORY regions when matchingKumar Gala2009-02-07-24/+78
| | | | | | | | | | When we search for an address match in pci_hose_{phys_to_bus,bus_to_phys} we should give preference to memory regions that aren't system memory. Its possible that we have over mapped system memory in the regions and we want to avoid depending on the order of the regions. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* pci: Rename PCI_REGION_MEMORY to PCI_REGION_SYS_MEMORY for clarityKumar Gala2009-02-07-7/+7
| | | | | | | | | | 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>

| | | | | | | | | fsl_pci_init.c: In function 'fsl_pci_setup_inbound_windows': fsl_pci_init.c:122: warning: comparison is always true due to limited range of data type The check only makes sense if we are CONFIG_PHYS_64BIT 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.

* powerpc: fix pci window initialization to work with > 4GB DRAMBecky Bruce2008-10-27-3/+7
| | | | | | | | | The existing code has a few errors that need to be fixed in order to support large RAM sizes. Fix those, and add a comment to make it clearer. Signed-off-by: Becky Bruce <becky.bruce@freescale.com> Acked-by: Kumar Gala <galak@kernel.crashing.org>

* pci/fsl_pci_init: Add a common PCI inbound setup functionKumar Gala2008-10-24-0/+81
| | | | | | | | Add a common setup function that determines the pci_region(s) based on how much memory we have in the system. Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Signed-off-by: Andrew Fleming-AFLEMING <afleming@freescale.com>
* pci/fsl_pci_init: Enable larger address and setting inbound windows properlyKumar Gala2008-10-24-14/+24
| | | | | | | | | | | | | | | | * PCI Inbound window was setup incorrectly. The PCI address and system address were swapped. The PCI address should be setting piwar/piwbear and the system address should be setting pitar. * Removed masking of addresses to allow for system address to support system address & PCI address >32-bits * Set PIWBEAR & POTEAR to allow for full 64-bit PCI addresses * Respect the PCI_REGION_PREFETCH for inbound windows Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Signed-off-by: Andrew Fleming-AFLEMING <afleming@freescale.com>
* pci: Allow for PCI addresses to be 64-bitKumar Gala2008-10-24-47/+78
| | | | | | | | | | PCI bus is inherently 64-bit. While not all system require access to the full 64-bit PCI address range some do. This allows those systems to enable the full PCI address width via CONFIG_SYS_PCI_64BIT.

* pci: Move PCI device configuration check into a separate weak functionStefan Roese2008-07-10-24/+46
| | | | | | | | | | | This patch moves the check, if a device should be skipped in PCI PNP configuration into the function pci_skip_dev(). This function is defined as weak so that it can be overwritten by a platform specific one if needed. The check if the device should get printed in the PCI summary upon bootup (when CONFIG_PCI_SCAN_SHOW is defined) is moved to the function pci_print_dev() which is also defined as weak too.

* Convert mpc7448hpc2 to CONFIG_OF_LIBFDTGerald Van Baren2008-06-09-14/+19
| | | | | | | | | | | | | This was configured to use the deprecated CONFIG_OF_FLAT_TREE, change to CONFIG_OF_LIBFDT. WARNING: This conversion is untested because I do not have a board to test it on. NOTE: The FDT blob (DTS) must have an /aliases/ethernet0 and (optionally) /aliases/ethernet1 property for the ethernet to work. Signed-off-by: Gerald Van Baren <vanbaren@cideas.com>
* Big white-space cleanup.Wolfgang Denk2008-05-21-22/+22
| | | | | | | | | | | This commit gets rid of a huge amount of silly white-space issues. Especially, all sequences of SPACEs followed by TAB characters get removed (unless they appear in print statements). Also remove all embedded "vim:" and "vi:" statements which hide indentation problems. Signed-off-by: Wolfgang Denk <wd@denx.de>

* Update pci code to use phys_addr_tBecky Bruce2008-05-10-4/+4
| | | | | | | | Physical addrs need to be represented by phys_addr_t, not unsigned long. Otherwise, systems that use CONFIG_PHYS_64BIT are going to fail mightily. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>

* pci: Add CONFIG_PCI_SKIP_HOST_BRIDGE config optionNobuhiro Iwamatsu2008-03-23-3/+10
| | | | | | | | | | | | In current source code, when the device number of PCI is 0, process PCI bridge without fail. However, when the device number is 0, it is not PCI always bridge. There are times when device of PCI allocates. When CONFIG_PCI_SKIP_HOST_BRIDGE is enable, this problem is solved when use this patch.
