* powerpc/axonram: Enable partitioning of the Axons DDR2 DIMMsMaxim Shchetynin2008-07-21
| | | | | | | | | | | DDR2 memory DIMMs on the Axon could be accessed only as one partition when using file system drivers which are using the direct_access() method. This patch enables for such file system drivers to access Axon's DDR2 memory even if it is splitted in several partitions.

* powerpc/axonram: Use only one block device major numberMaxim Shchetynin2008-07-21
| | | | | | | | | | | Axonram module registers one block device for each DDR2 DIMM found on a system. This means that each DDR2 DIMM becomes its own block device major number. This patch lets axonram module to register the only one block device for all DDR2 DIMMs which also spares kernel resources.

| * | powerpc/4xx: Workaround for PPC440EPx/GRx PCI_28 ErrataJosh Boyer2008-06-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 440EPx/GRx chips don't support PCI MRM commands. Drivers determine this by looking for a zero value in the PCI cache line size register. However, some drivers write to this register upon initialization. This can cause MRMs to be used on these chips, which may cause deadlocks on PLB4. The workaround implemented here introduces a new indirect_type flag, called PPC_INDIRECT_TYPE_BROKEN_MRM. This is set in the pci_controller structure in the pci fixup function for 4xx PCI bridges by determining if the bridge is compatible with 440EPx/GRx. The flag is checked in the indirect_write_config function, and forces any writes to the PCI_CACHE_LINE_SIZE register to be zero, which will disable MRMs for these chips. A similar workaround has been tested by AMCC on various PCI cards, such as the Silicon Image ATA card and Intel E1000 GIGE card. Hangs were seen with the Silicon Image card, and MRMs were seen on the bus with a PCI analyzer. With the workaround in place, the card functioned properly and only Memory Reads were seen on the bus with the analyzer.

Less trivial changes: - BD_SC_* defines were defined in the cpm.h and qe.h, so to avoid redefines we remove BD_SC from the qe.h and use cpm.h along with cpm_muram_* prototypes; - qe_muram_dump was unused and thus removed; - added some code to the cpm_common.c to support legacy QE bindings (data-only node name). - For convenience, define qe_* calls to cpm_*.

* | | powerpc/QE: add support for QE USB clocks routingAnton Vorontsov2008-06-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a function to the qe_lib to setup QE USB clocks routing. To setup clocks safely, cmxgcr register needs locking, so I just reused ucc_lock since it was used only to protect cmxgcr. The idea behind placing clocks routing functions into the qe_lib is that later we'll hopefully switch to the generic Linux Clock API, thus, for example, FHCI driver may be used for QE and CPM chips without nasty #ifdefs. This patch also fixes QE_USB_RESTART_TX command definition in the qe.h.

Before using the MSI interrupt, PCI/PCIE device need to ask for a MSI interrupt in the 256 MSI interrupts. A 256bit bitmap show which MSI interrupt was used, reserve bit in the bitmap can be used to force the device use some designate MSI interrupt in the 256 MSI interrupts. Sometimes this is useful for testing the all the MSI interrupts. The msi-available-ranges property in the dts file was used for this purpose.

Although this works for most platforms, it fails on FPGA platforms: 1) Systems may include more than one DCR bus. 2) Systems may be native DCR capable and still use memory mapped DCR interface. This patch provides runtime support based on the device trees for the case where CONFIG_PPC_DCR_MMIO and CONFIG_PPC_DCR_NATIVE are both selected. Previously, this was a poorly defined configuration, which happened to provide NATIVE support. The runtime selection is made based on the dcr-controller having a 'dcr-access-method' attribute in the device tree. If only one of the above options is selected, then the code uses #defines to select only the used code in order to avoid introducing overhead in existing usage.

| * [POWERPC] 4xx: Add endpoint support to 4xx PCIe driverStefan Roese2008-05-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds basic endpoint support to the 4xx PCIe driver. This is done by checking the device_type property of the PCIe device node ("pci" for root-complex and "pci-endpoint" for endpoint configuration). Note: Currently we map a fixed 64MByte window to PLB address 0 (SDRAM). This should probably be configurable via a dts property.
