* powerpc/85xx: Add P2020DS board supportKumar Gala2009-05-19
| | | | | | | | | | | | | | | | | | | The P2020 is a dual e500v2 core based SOC with: * 3 PCIe controllers * 2 General purpose DMA controllers * 2 sRIO controllers * 3 eTSECS * USB 2.0 * SDHC * SPI, I2C, DUART * enhanced localbus * and optional Security (P2020E) security w/XOR acceleration The p2020 DS reference board is pretty similar to the existing MPC85xx DS boards and has a ULI 1575 connected on one of the PCIe controllers.

* powerpc/8xxx: Update PCI outbound window addresses for 36-bit configsKumar Gala2009-05-19
| | | | | | | | | | | | | In these configuration we expect to have large amounts of memory (> 4G) and thus will bounce via swiotlb some region of PCI address space. The outbound windows were wasting 512M of address space by leaving a gap between the top of the outbound window and the 4G boundary. By moving the top of the outbound window up to the 4G boundary we can reclaim the vast majority of the 512M (minus space needed for PEXCSRBAR) and thus reduces the amount of memory we have to bounce.

* powerpc/fsl: Support unique MSI addresses per PCIe Root ComplexKumar Gala2009-05-19
| | | | | | | | | | Its feasible based on how the PCI address map is setup that the region of PCI address space used for MSIs differs for each PHB on the same SoC. Instead of assuming that the address mappes to CCSRBAR 1:1 we read PEXCSRBAR (BAR0) for the PHB that the given pci_dev is on. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | | | | Note that eSDHC and DUART0 are mutually exclusive on MPC8569E-MDS boards. Default option is DUART0, so eSDHC is disabled by default.

* powerpc/fsl: Removed reg property from 85xx/86xx soc nodeKumar Gala2009-05-19
| | | | | | | | | | | Between the addition of the ecm/mcm law nodes and the fact that the get_immrbase() has been using the range property of the SoC to determine the base address of CCSR space we no longer need the reg property at the soc node level. It has been ill specified and varied between device trees to cover either the {e,m}cm-law node, some odd subset of CCSR space or all of CCSR space.

| | | | | | | | | | | | | | | | The latest QE chip may have more Serial Number(SNUM)s of thread to use. We will get the number of SNUMs from device tree by reading the new property "fsl,qe-num-snums", and set 28 as the default number of SNUMs so that it is compatible with the old QE chips' device trees which don't have this new property. The macro QE_NUM_OF_SNUM is defined as the maximum number in QE snum table which is 256. Also we update the snum_init[] array with 18 more new SNUMs which are confirmed to be useful on new chip.

* powerpc: make dma_window_* in pci_controller struct avail on 32bBecky Bruce2009-05-19
| | | | | | | | | | | | | | | | Also, convert them to resource_size_t (which is unsigned long on 64-bit, so it's not a change there). We will be using these on fsl 32b to indicate the start and size address of memory that the pci controller can actually reach - this is needed to determine if an address requires bounce buffering. For now, initialize them to a standard value; in the near future, the value will be calculated based on how the inbound windows are programmed.

Fix this by splitting up the warn_slowpath_null/fmt cases differently, using a common helper function, and getting the return address in the right place. This also happens to avoid the unnecessary stack usage for the non-stdargs case, and just generally cleans things up. Make the function name printout use %pS while at it.
