2009-05-21powerpc/pci: Clean up direct access to sysdata by 4xx platformsKumar Gala
We shouldn't directly access sysdata to get the pci_controller. Instead use pci_bus_to_host() for this purpose. In the future we might have sysdata be a device_node to match ppc64 and unify the code between ppc32 & ppc64.

2009-05-21powerpc: Fix up elf_read_implies_exec() usageKumar Gala
We believe if a toolchain supports PT_GNU_STACK that it sets the proper PHDR permissions. Therefor elf_read_implies_exec() should only be true if we don't see PT_GNU_STACK set. Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

2009-05-21powerpc/ps3: Use smp_request_message_ipiGeoff Levand

2009-05-21powerpc/pseries: CMO unused page hintingRobert Jennings
Adds support for the "unused" page hint which can be used in shared memory partitions to flag pages not in use, which will then be stolen before active pages by the hypervisor when memory needs to be moved to LPARs in need of additional memory. Failure to mark pages as 'unused' makes the LPAR slower to give up unused memory to other partitions. This adds the kernel parameter 'cmo_free_hint' to disable this functionality.

2009-05-21powerpc/mpic: Cleanup mpic_find() implementationTony Breeds
mpic_find() was overloaded to do two things, finding the mpic instance for a given interrupt and returning if it's an IPI. Instead we introduce mpic_is_ipi() and simplify mpic_find() to just return the mpic instance Also silences the warning: arch/powerpc/sysdev/mpic.c: In function 'mpic_irq_set_priority': arch/powerpc/sysdev/mpic.c:1382: warning: 'is_ipi' may be used uninitialized in this function Signed-off-by: Tony Breeds <tony@bakeyournoodle.com> Acked-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2009-05-21powerpc: Update Warp to use leds-gpio driverSean MacLennan
Now that leds-gpio is a proper OF platform driver, the Warp can use the leds-gpio driver rather than the old out-of-kernel driver. One side-effect is the leds-gpio driver always turns the leds off while the old driver left them alone. So we have to set them back to the correct settings.

2009-05-19powerpc/fsl: Setup PCI inbound window based on actual amount of memoryKumar Gala
Previouslly we just always set the inbound window to 2G. This was broken for systems with >2G. If a system has >=4G we will need SWIOTLB support to handle that case. We now allocate PCICSRBAR/PEXCSRBAR right below the lowest PCI outbound address for MMIO or the 4G boundary (if the lowest PCI address is above 4G). Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2009-05-19powerpc/85xx: Add P2020DS board supportKumar Gala
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.

We we build with resource_size_t as a 64-bit quantity we get: arch/powerpc/sysdev/fsl_rio.c: In function 'fsl_rio_setup': arch/powerpc/sysdev/fsl_rio.c:1029: warning: format '%08x' expects type 'unsigned int', but argument 4 has type 'resource_size_t' arch/powerpc/sysdev/fsl_rio.c:1029: warning: format '%08x' expects type 'unsigned int', but argument 5 has type 'resource_size_t' Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2009-05-19powerpc/8xxx: Update PCI outbound window addresses for 36-bit configsKumar Gala
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. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2009-05-19powerpc/fsl: Support unique MSI addresses per PCIe Root ComplexKumar Gala
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>
2009-05-19powerpc/85xx: Add MSI nodes for MPC8568/9 MDS systemsKumar Gala

2009-05-19powerpc/85xx: Add STMicro M25P40 serial flash support for MPC8569E-MDSAnton Vorontsov

2009-05-19powerpc/85xx: Add eSDHC support for MPC8569E-MDS boardsAnton Vorontsov
Note that eSDHC and DUART0 are mutually exclusive on MPC8569E-MDS boards. Default option is DUART0, so eSDHC is disabled by default. U-Boot will fixup device tree if eSDHC should be used instead of DUART0. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2009-05-19powerpc/85xx: Add PCI IDs for MPC8569 family processorsAnton Vorontsov
This patch adds PCI IDs for MPC8569 and MPC8569E processors, plus adds appropriate quirks for these IDs, and thus makes PCI-E actually work on MPC8569E-MDS boards. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2009-05-19powerpc/fsl: Removed reg property from 85xx/86xx soc nodeKumar Gala
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.

2009-05-19powerpc/qe: update QE Serial NumberHaiying Wang
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.

2009-05-19powerpc/86xx: clean up smp init codeKumar Gala
Removed the need for asm/mpc86xx.h as it was only used in mpc86xx_smp.c and just moved the defines it cared about into there. Also fixed up the ioremap to only map the one 4k page we need access to and to iounmap when we are done. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2009-05-19powerpc: make dma_window_* in pci_controller struct avail on 32bBecky Bruce
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.

2009-05-19powerpc/fsl: use of_iomap() for rstcr mappingKumar Gala

2009-05-19powerpc: Refactor board check for PCI quirks on FSL boards with uli1575Kumar Gala
