| * | [POWERPC] Abolish powerpc_flash_init()David Gibson2007-05-082-33/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | powerpc_flash_init() implements a broken way of probing for flash devices supported by the physmap_of driver. It finds all nodes in the device tree with device_type=="rom" and instantiates of_platform devices for them. This is fundamentally incompatible with the normal and correct way of probing for of_platform_bus_probe(). Platforms which relied on powerpc_flash_init()s behaviour (none are in-tree) will have to update their platform probing code to correctly probe busses containing flash devices.

This includes both code in arch/powerpc/platforms/44x for board initialization, and zImage wrapper code to correctly tweak the flattened device tree based on information from the firmware.

| * | [POWERPC] Add powerpc/platforms/44x, disable platforms/4xx for nowDavid Gibson2007-05-085-11/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This prepares for Ebony/440 support by creating an arch/powerpc/platforms/44x directory. It is populated with a single misc_44x.S file, into which is moved the 44x specific reset code from head_44x.S (on the grounds that we should really stop clogging up the head_* files with random asm helper routines). At the same time, we disable the (empty save Kconfig and Makefile) arch/powerpc/platforms/4xx directory from the arch/powerpc/platforms Makefile. Contrary to the comment in arch/powerpc/platforms/4xx/Makefile, attempting to build such an empty Makefile will fail, thus breaking compile for the 44x platforms we're about to add. It can go back in once we start porting some of the 40x platforms (and thus it becomes non-empty).

| * | [POWERPC] MPIC U3/U4 MSI backendMichael Ellerman2007-05-084-6/+205
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MPIC U3/U4 MSI backend. Based on code from Segher, heavily hacked by me. This only deals with MSI on U3/U4 MPICs, aka. CPC 9x5. If we find a U3/U4 then we enable this backend, ie. take over the ppc_md MSI hooks. We might need more elaborate logic in future to decide which backend is enabled. We need our own irq_chip so that we can do MSI masking/unmasking on the device itself. We also need to mask explicitly on shutdown to make sure we don't get bitten by lazy-disable semantics.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To support MSI on MPIC we need a way to reserve and allocate hardware irq numbers, this patch implements an allocator for that purpose. New firmware platforms must define a "msi-available-ranges" property on their MPIC node for MSI to work. For U3/U4 we do a best-guess setup.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement MSI support via RTAS (RTAS = run-time firmware on pSeries machines). For now we assumes that if the required RTAS tokens for MSI are present, then we want to use the RTAS MSI routines. When RTAS is managing MSIs for us, it will/may enable MSI on devices that support it by default. This is contrary to the Linux model where a device is in LSI mode until the driver requests MSIs. To remedy this we add a pci_irq_fixup call, which disables MSI if they've been assigned by firmware and the device also supports LSI. Devices that don't support LSI at all will be left as is, drivers are still expected to call pci_enable_msi() before using the device. At the moment there is no pci_irq_fixup on pSeries, so we can just set it unconditionally. If other platforms use the RTAS MSI backend they'll need to check that still holds.

We implement the newly added arch_setup_msi_irqs() and arch_teardown_msi_irqs(), and then delegate to ppc_md routines. Platforms that don't implement MSI will leave the ppc_md calls blank, arch_msi_check_device() will detect this and return ENOSYS. Drivers should detect this error and continue to use LSI.

| * | [POWERPC] Remove use of 4level-fixup.h for ppc32David Gibson2007-05-082-13/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For 32-bit systems, powerpc still relies on the 4level-fixup.h hack, to pretend that the generic pagetable handling stuff is 3-levels rather than 4. This patch removes this, instead using the newer pgtable-nopmd.h to handle the elision of both the pud and pmd pagetable levels (ppc32 pagetables are actually 2 levels). This removes a little extraneous code, and makes it more easily compared to the 64-bit pagetable code.

| * | [POWERPC] Cope with PCI host bridge I/O window not starting at 0Paul Mackerras2007-05-081-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently our code to set up the data structures for a PCI host bridge and create the mapping for its I/O window assumes that the window starts at I/O port 0 on the PCI side. If this is not true, we can end up with I/O port numbers in the resources for PCI devices which will cause an oops if a driver tries to access them via inb/outb etc., because there is no mapping for the corresponding addresses. Normally the I/O window starts at 0, but there are some situations on partitioned machines with a hypervisor where the window may not start at 0. This fixes the problem by allocating space for the range from 0 to the end of the I/O window. That is, hose->io_base_virt contains the virtual address for I/O port 0 on the PCI bus, and thus the assumption that hose->io_base_virt - pci_io_base is the offset between the "global" I/O port numbers (those in the PCI device resources) and the I/O port numbers on the PCI bus is maintained. For PCI host bridges that are present at boot, we only map the portion of that range that correspond to the bridge's I/O window. For bridges added after boot we ioremap the range from 0 to the end of the I/O window, for now; in fact hot-added bridges should be using reserve_phb_iospace() and __ioremap_explicit (so they get sensible global port numbers), but we don't have the infrastructure yet to do that (basically a free_phb_iospace() routine plus appropriate locking). Interestingly, this makes the two arms of the if statement in get_bus_io_range do almost exactly the same thing; that function could now be simplified in a further patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a couple of missing dependencies in arch/powerpc/boot/Makefile. First, it ensures that the zlib.h header is linked in before attempting to build gunzip_util.o, as it is, building gunzip_util.o usually works, but not always depending on make order. Second, it makes the final images which are built using a dts dependent on that dts, so the image will be correctly rebuilt if the dts changes. This in turn requires fixing the definition of the dts variable. CONFIG_DEVICE_TREE from Kconfig will have quotes around it, which don't matter when passing the variable to a shell, but which need to be removed when incorporating it into a filename for make's use.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows the zImage target to once again be used to build all supported image types, rather than requiring an explicit "make uImage" to avoid failing to create an unneeded cuImage.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new function named smp_call_function_single(). This matches a generic prototype from include/linux/smp.h. Add a function smp_call_function_map(). This is, for the most part, a rename of smp_call_function, with some added cpumask support. smp_call_function and smp_call_function_single call into smp_call_function_map. Lightly tested on 970mp (blade), power4 and power5. Signed-off-by: Will Schmidt <will_schmidt@vnet.ibm.com> cc: Anton Blanchard <anton@samba.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds mpic to the system devices and implements suspend and resume for them. This is necessary to get interrupts for modules back to where they were before a suspend to disk.

| * | [POWERPC] 64K page support for kexecLuke Browning2007-05-071-22/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a couple of kexec problems related to 64K page support in the kernel. kexec issues a tlbie for each pte. The parameters for the tlbie are the page size and the virtual address. Support was missing for the computation of these two parameters for 64K pages. This adds that support.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes a few small cleanups to the cuboot code. - It removes the double layered selection of images, via cuboot-plat-y, instead having the cuboot platforms directly select a suitable image-y (this changes the name of the final cuboot image from plain cuImage to cuImage.<platform>). - Factors out some code in the wrapper that's potentially useful to platforms other than uboot.
