2012-12-13MIPS/EDAC: Improve OCTEON EDAC support.David Daney
Some initialization errors are reported with the existing OCTEON EDAC support patch. Also some parts have more than one memory controller. Fix the errors and add multiple controllers if present. Signed-off-by: David Daney <david.daney@cavium.com>
2012-12-12MIPS: Cavium: Add EDAC support.Ralf Baechle
Drivers for EDAC on Cavium. Supported subsystems are: o CPU primary caches. These are parity protected only, so only error reporting. o Second level cache - ECC protected, provides SECDED. o Memory: ECC / SECDEC if used with suitable DRAM modules. The driver will will only initialize if ECC is enabled on a system so is safe to run on non-ECC memory. o PCI: Parity error reporting Since it is very hard to test this sort of code the implementation is very conservative and uses polling where possible for now.

2012-09-18PCI: Provide a default pcibios_update_irq()Thierry Reding
Most architectures implement this in exactly the same way. Instead of having each architecture duplicate this function, provide a single implementation in the core and make it a weak symbol so that it can be overridden on architectures where it is required.

2012-09-18PCI: Discard __init annotations for pci_fixup_irqs() and related functionsThierry Reding
Remove the __init annotations in order to keep pci_fixup_irqs() around after init (e.g. for hotplug). This requires the same change for the implementation of pcibios_update_irq() on all architectures. While at it, all __devinit annotations are removed as well, since they will be useless now that HOTPLUG is always on.

2012-07-19MIPS: PCI: Move fixups from __init to __devinit.Sebastian Andrzej Siewior
Fixups are executed once the pci-device is found which is during boot process so __init seems fine as long as the platform does not support hotplug. However it is possible to remove the PCI bus at run time and have it rediscovered again via "echo 1 > /sys/bus/pci/rescan" and this will call the fixups again.

As long as there is no other non-const variable marked __initdata in the same compilation unit it doesn't hurt. If there were one however compilation would fail with error: $variablename causes a section type conflict because a section containing const variables is marked read only and so cannot contain non-const variables.

2012-07-03MIPS: Netlogic: MSI enable fix for XLSGanesan Ramalingam
MSI interrupts do not work on XLS after commit a776c49 ( "PCI: msi: Disable msi interrupts when we initialize a pci device" ) because the change disables MSI interrupts on the XLS PCIe bridges during the PCI enumeration. Fix this by enabling MSI interrupts on the bridge in the arch_setup_msi_irq() function. A new function xls_get_pcie_link() has been introduced to get the PCI device corresponding to the top level PCIe bridge on which MSI has to be enabled. Also, update get_irq_vector() to use the new xls_get_pcie_link() function and PCI_SLOT() macro for determining the IRQ of PCI devices.

2012-05-15MIPS: ath79: add a workaround for a PCI controller bug in AR7240 SoCsGabor Juhos
The PCI controller of the AR724X SoCs has a hardware bag. If the BAR0 register of the PCI device is set to the proper base address, the memory address space of the device is not accessible. When the device driver tries to access the memory address space of the PCI device, it leads to data bus error, similiar to this: Data bus error, epc == 801f69a0, ra == 801f698c Oops[#1]: Cpu 0 $ 0 : 00000000 00000061 deadbeef 000000ff $ 4 : 00000000 000000ff 00000014 00000000 $ 8 : ff000000 fffffffc 00000000 00000000 $12 : 000001f5 00000006 00000000 6e637920 $16 : 81ca4000 81ca0260 81ca4000 804d70f0 $20 : fffffff4 0000002b 803ad4c4 00000000 $24 : 00000003 00000000 $28 : 81c20000 81c21c60 00000000 801f698c Hi : 00000000 Lo : 00000000 epc : 801f69a0 ath9k_hw_init+0xd0/0xa70 Not tainted ra : 801f698c ath9k_hw_init+0xbc/0xa70 Status: 1000c103 KERNEL EXL IE Cause : 1080001c PrId : 00019374 (MIPS 24Kc) Modules linked in: Process swapper (pid: 1, threadinfo=81c20000, task=81c18000, tls=00000000) Stack : 00000000 00000000 00000000 00000000 81c21c78 81ca0260 00000000 804d70f0 81ca0260 81c21cc0 81ca0e80 81ca0260 81ca4000 804d70f0 fffffff4 0000002b 803ad4c4 00000000 00000000 801e3ae8 81c9d080 81ca0e80 b0000000 800b9b9c 00000008 81c9d000 8031aeb0 802d38a0 00000000 81c14c00 81c14c60 00000000 81ca0e80 81ca0260 b0000000 801f08a4 81c9c820 81c21d48 81c9c820 80144320 ...

2012-05-15MIPS: ath79: fix broken ar724x_pci_{read,write} functionsGabor Juhos
The current ar724x_pci_{read,write} functions are broken. Due to that, pci_read_config_byte returns with bogus values, and pci_write_config_{byte,word} unconditionally clears the accessed PCI configuration registers instead of changing the value of them. The patch fixes the broken functions, thus the PCI configuration space can be accessed correctly.
