* powerpc/pci: Clean up direct access to sysdata on tsi108 platformsKumar Gala2009-05-211-2/+2
| | | | | | | | | | 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.

* powerpc/mpic: Cleanup mpic_find() implementationTony Breeds2009-05-211-12/+11
| | | | | | | | | | | | | | 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>
* powerpc/fsl: Setup PCI inbound window based on actual amount of memoryKumar Gala2009-05-192-21/+115
| | | | | | | | | | | | 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).

* powerpc/fsl: Support unique MSI addresses per PCIe Root ComplexKumar Gala2009-05-191-2/+7
| | | | | | | | | | 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>

* powerpc/qe: update QE Serial NumberHaiying Wang2009-05-191-4/+43
| | | | | | | | | | | | | | | | 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 Bruce2009-05-191-0/+4
| | | | | | | | | | | | | | | | 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.

* powerpc/mpic: Fix incorrect allocation of interrupt rev-mapKumar Gala2009-05-151-7/+9
| | | | | | | | | | | | | | | Before when we were setting up the irq host map for mpic we passed in just isu_size for the size of the linear map. However, for a number of mpic implementations we have no isu (thus pass in 0) and will end up with a no linear map (size = 0). This causes us to always call irq_find_mapping() from mpic_get_irq(). By moving the allocation of the host map to after we've determined the number of sources we can actually benefit from having a linear map for the non-isu users that covers all the interrupt sources.

The combination of bits defining access to kernel pages are now clearly separated from the combination used by userspace and the core VM. The resulting generated code should remain identical unless I made a mistake. Note: While at it, I removed a non-sensical statement related to CONFIG_KGDB in ppc_mmu_32.c which could cause kernel mappings to be user accessible when that option is enabled.

| * | | | powerpc/44x: Fix address decoding setup of PCI 2.x cellsBenjamin Herrenschmidt2009-02-261-0/+17
| | |_|/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PCI 2.x cells used on some 44x SoCs only let us configure the decode for the low 32-bit of the incoming PLB addresses. The top 4 bits (this is a 36-bit bus) are hard wired to different values depending on the specific SoC in use. Our code used to work "by accident" until I added support for the ISA memory holes and while at it added more validity checking of the addresses. This patch should bring it back to working condition. It still relies on the device-tree being correct but that's somewhat a pre-requisite for anything to work anyway.

* | | | powerpc/83xx: Do not configure or probe disabled FSL DR USB controllersAnton Vorontsov2009-03-091-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On MPC837X CPUs Dual-Role USB isn't always available (for example DR USB pins can be muxed away to eSDHC). U-Boot adds status = "disabled" property into the DR USB nodes to indicate that we must not try to configure or probe Dual-Role USB, otherwise we'll break eSDHC support on targets with MPC837X CPUs.

* | | | powerpc/83xx: Fix the interrupt loss problem on ipicdayu@datangmobile.cn2009-03-091-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The interrupt pending register is write 1 clear. If there are more than one external interrupts pending at the same time, acking the first interrupt by reading pending register then OR the corresponding bit and write back to pending register will also clear other interrupt pending bits. That will cause loss of interrupt. Signed-off-by: Da Yu <dayu@datangmobile.cn> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* | | | powerpc/4xx: Enable PCI domains on 4xxBenjamin Herrenschmidt2009-02-141-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 4xx chips commonly now have multiple PHBs, there is no reason to not enable PCI domains on them. The main issue with PCI domains is X but currently its already somewhat busted for other reasons such as the 36-bit physical address space, which I'm fixing separately.

| * | | powerpc/fsl_pci: Add MPC83xx PCI-E controller RC mode supportAnton Vorontsov2009-01-291-24/+220
| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for PCI-Express controllers as found on the newer MPC83xx chips. The work is loosely based on the Tony Li's patch[1], but unlike the original patch, this patch implements sliding window for the Type 1 transactions using outbound window translations, so we don't have to ioremap the whole PCI-E configuration space.

* | | powerpc/cpm2: Fix set interrupt typepaulfax2009-02-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a simple change to correct problems when using set_irq_type on platforms using CPM2. This code corrects the problem on most platform but may have issues on 8272 derived platforms for some interrupts. On 8272 PC2 & 3 are missing and PC 23 & 29 are added, which this patch does not address.
