Generalize tsi108_setup_pci to take the config space physical address and primary bus designator as a parameter. Signed-off-by:

Josh Boyer authored
Add a phy_type field to the tsi108 ethernet structures to indicate which PHY is used on a board. This is derived from the "compatible" property in the ethernet-phy node of the device tree. The default remains the MV88E PHY. Also, convert the setup code to use of_get_mac_address instead of hard coding a lookup for the "address" property in the ethernet node. Signed-off-by:

The generic LED code now makes sure that suspended devices don't blink, so we no longer need to do it ourselves. For the suspend to disk case, however, we need to make sure that we don't blink if the PMU sysdev was suspended before the LED device. Signed-off-by:

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. Signed-off-by:

ppc4xx_sgdma.c is #including asm/dma-mapping.h directly, which should only ever be included via linux/dma-mapping.h. asm/dma-mapping.h relies on an enum defined in linux/dma-mapping.h before its own include. This fixes the problem. Signed-off-by:

Implement deep-sleep on MPC52xx. SDRAM is put into self-refresh with help of SRAM code (alternatives would be code in FLASH, I-cache). Interrupt code must also not be in SDRAM, so put it in I-cache. MPC52xx core is static, so contents will remain intact even with clocks turned off. Signed-off-by:

There is now a common function to generate the modalias string, so use it. We just need to add the \n at the end. Signed-off-by:
-
Sylvain Munaut authored
Apparently other parts of the kernel need to know the modalias internally (like the sysfs code in macintosh driver). To avoid consistency issues, we export this code and use it everywhere it's needed rather than repeat it ... Signed-off-by:

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.

32-bit powerpc uses a PTE_FMT macro to handle printk() formatting of PTE entries (which can vary in type and size). Apparently there was a good reason for it once, but with current compilers it's simpler just to workaround the variation with a cast in the printk() itself (there's only one use). Signed-off-by:

Powermac G5 suspend to disk implementation. The code is platform agnostic but only tested on powermac, no other 64-bit powerpc machines. Because nvidiafb still breaks suspend I have marked it EXPERIMENTAL on powermac and because I can't test it and some lowlevel code will need changes it is BROKEN on all other 64-bit platforms.

This allows "hotplugging" of CPUs on G5 machines. CPUs that are disabled are put into an idle loop with the decrementer frequency set to minimum. To wake them up again we kick them just like when bringing them up. To stop those CPUs from messing with any global state we stop them from entering the timer interrupt. Signed-off-by:

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:

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. Signed-off-by:

When data symbols are not present in kernel image, user needs to add dot(".") before function name explicitly, that he wants to probe in kprobe module on ppc64. for ex:- When data symbols are missing on ppc64, ==================== [root@llm27lp1 ~]# cat /proc/kallsyms | grep do_fork c00000000006283c T .do_fork ============================== User needs add "." to "do_fork" kp.symbol_name = ".do_fork"; ============================ This makes kprobe modules unportable.

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.
