/proc/vmcore wasn't showing up in kdump kernels. It turns that that for Octeon, the memory used by elfcorehdr wasn't being set aside properly and it was getting clobbered before /proc/vmcore could get it. So reserve the memory if it shows up in a memory area managed by the kernel. Signed-off-by:

Kernel memory isn't necessarily added to the memory tables, so it wouldn't show up in /proc/iomem. This was breaking kdump, which requires these memory addresses to work correctly. Signed-off-by:

The current code uses static resources and static platform device instances for the possible USB controllers in the system. These static variables contains initial values which leads to data segment pollution. Remove the static variables and use dynamically allocated structures instead. Signed-off-by:

The command register of the PCI controller is not initialized correctly by the bootloader on some boards and this leads to non working PCI bus. Add code to initialize the command register from the Linux code to avoid this. Signed-off-by:

Change to the code to use per-controller IRQ base. This is needed for multiple PCI controller support. Signed-off-by:

Static resources become impractical when multiple PCI controllers are present. Move the resources into the platform device registration code and change the probe routine to get those from there platform device's resources. Signed-off-by:

The current code uses static variables to store the PCI controller specific data. This works if the system contains one PCI controller only, however it becomes impractical when multiple PCI controllers are present. Move the variables into a dynamically allocated controller specific structure, and use that instead of the static variables. Signed-off-by:

The pci_load_of_ranges function is only available if CONFIG_OF is selected. If the function is used without CONFIG_OF being enabled it will cause a build error. Add a dummy inline function to avoid this. Signed-off-by:

The IO and memory resources of a PCI controller might already have a parent resource set when they are passed to 'register_pci_controller'. If the parent resource is set, the request_resource call will fail due to resource conflict and the current code will not be able to register the PCI controller. Use the parent resource if it is available in the request_resource call to avoid the isssue. Signed-off-by:

The pci-ar71xx and pci-ar724x drivers were converted into platform drivers. Register the corresponding platform devices for the PCI controllers instead of using the ar7{1x,24}x_pcibios_init functions. Signed-off-by: -

The patch converts the pci-ar71xx driver into a platform driver. This makes it possible to register the PCI controller as a plain platform device. Signed-off-by:

Until there is a generic MIPS way of handing the DTB over from bootloader to kernel we rely on a built in devicetrees. The OF code also remaps those register ranges that we use global in our drivers. Signed-off-by:

The current code uses multiple if statements for demultiplexing the different interrupt sources. Additionally, the MISC interrupt controller has 32 interrupt sources and the current code does not handles all of them. Get rid of the if statements and process all interrupt sources in a loop to fix these issues. Signed-off-by:

GPIO function selection is not working on the AR934x SoCs because the offset of the function selection register is different on those. Add a helper routine which returns the correct register address based on the SoC type, and use that in the 'ath79_gpio_function_*' routines. Signed-off-by:
