* 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: 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>

* 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.

* 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.
