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. Signed-off-by:

Rather than a giant ifdef in the body of do_IRQ(), including a dangling else, move the irq stack logic into a separate routine and do the ifdef there. Signed-off-by:

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. Signed-off-by:

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:

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. Signed-off-by:

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: -

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.

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.

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: -

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. Signed-off-by: -

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.
