pci: tegra: Update error prints with new lines

2022-06-13T22:31:00Z

Add new lines to make errorr messages easier to read. Signed-off-by: Peter Robinson Signed-off-by: Tom Warren

pci: Add config for Enhanced Allocation

2022-05-03T22:33:29Z

Add a config to control whether Enhanced Allocation is supported by the driver. Signed-off-by: Andrew Scull

pci: Add mask parameter to dm_pci_map_bar()

2022-05-03T22:33:29Z

Add a mask parameter to control the lookup of the PCI region from which the mapping can be made. Signed-off-by: Andrew Scull Reviewed-by: Bin Meng

pci: Update dm_pci_bus_to_virt() parameters

2022-05-03T22:33:29Z

Add mask parameter and reorder length parameter to match the other PCI address conversion functions. Using PCI_REGION_TYPE as the mask gives the old behaviour. It's converted from a macro to an inline function as the length parameter is now used twice, but should only be calculated once. Signed-off-by: Andrew Scull Reviewed-by: Bin Meng

pci: Match region flags using a mask

2022-05-03T22:33:26Z

When converting addresses, apply a mask to the region flags during lookup. This allows the caller to specify which flags are important and which are not, for example to exclude system memory regions. The behaviour of the function is changed such that they don't preferentially search for a non-system memory region. However, system memory regions are added after other regions in decode_regions() leading to a similar outcome. Signed-off-by: Andrew Scull Reviewed-by: Bin Meng

pci: Map bars with offset and length

2022-05-03T19:50:46Z

Evolve dm_pci_map_bar() to include an offset and length parameter. These allow a portion of the memory to be mapped and range checks to be applied. Passing both the offset and length as zero results in the previous behaviour and this is used to migrate the previous callers. Signed-off-by: Andrew Scull Reviewed-by: Bin Meng

pci: Range check address conversions

2022-05-03T19:50:45Z

When converting between PCI bus and physical addresses, include a length parameter that can be used to check that the entire range fits within one of the PCI regions. This prevents an address being returned that might be only partially valid for the range it is going to be used for. Where the range check is not wanted, passing a length of 0 will have the same behaviour as before this change. Signed-off-by: Andrew Scull Reviewed-by: Bin Meng

pci: Check region ranges are addressable

2022-05-03T19:50:45Z

When parsing the `ranges` DT node, check that both extremes of the regions are addressable without overflow. This assumption can then be safely made when processing the regions. Signed-off-by: Andrew Scull Reviewed-by: Bin Meng

pci: Fix use of flags in dm_pci_map_bar()

2022-05-03T19:50:45Z

The flags parameter of dm_pci_map_bar() is used for PCI region flags rather than memory mapping flags. Fix the type to match that of the region flags and stop using the regions flags as memory mapping flags. Signed-off-by: Andrew Scull Reviewed-by: Bin Meng

pci: fsl: Change compatible string for mpc8548 to "fsl, mpc8548-pcie"

2022-04-26T11:48:39Z

Upstream Linux kernel uses for mpc8548-based PCIe controllers compatible string "fsl,mpc8548-pcie". So change U-Boot fsl PCIe driver and all DTS files to use "fsl,mpc8548-pcie" instead of "fsl,pcie-mpc8548" to be compatible with Linux kernel. Signed-off-by: Pali Rohár Reviewed-by: Priyanka Jain
