Introduce a new dma attriblue DMA_ATTR_WEAK_ORDERING to use weak ordering on DMA mappings in the Cell processor. Add the code to the Cell's IOMMU implementation to use this code. Dynamic mappings can be weakly or strongly ordered on an individual basis but the fixed mapping has to be either completely strong or completely weak. This is currently decided by a kernel boot option (pass iommu_fixed=weak for a weakly ordered fixed linear mapping, strongly ordered is the default). Signed-off-by:

While running on a system with new hardware and a kernel where the cpu_specs[] table does not recognize the new hardware, the identify_cpu() routine will select the default case as it searches through cpu_specs[] in an attempt to match the real PVR. Once the default case is selected, non of the oprofile counters and/or fields have been set up or defined. When identify_cpu() is called once more with the logical PVR, some of the cpu specific fields are replaced with the exception of the oprofile related ones. However, in the case where we have actually taken the default case while searching for the real PVR, we need to tell oprofile that we are now running in compatibility mode so it can pick up the correct counters. We do this by setting the oprofile_cpu_type field to be that taken from the cpu_specs[] for the cpu we are now emulating. This change will detect that we are now altering the real PVR and determine if we also need to update the oprofile_cpu_type field. Signed-off-by:

For C code spaces versus tabs is just a religious issue, but for Makefiles it actually matters. This patch fixes he following errors: /home/bunk/linux/kernel-2.6/git/linux-2.6/arch/powerpc/boot/Makefile:166: *** missing separator. Stop. /home/bunk/linux/kernel-2.6/git/linux-2.6/arch/powerpc/boot/Makefile:171: *** missing separator. Stop. Since this was inside an ifdef DTC_GENPARSER it was not a problem unless someone wanted to regenerate the shipped generated files. Signed-off-by:

Add a #define for aligning to a long-sized boundary. It would be nice to use sizeof(long) for this, but that requires generating the value with asm-offsets.c, and asm-offsets.c includes asm-compat.h and we descend into some sort of recursive include hell. Signed-off-by:

The OF parsing code for PCI addresses isn't always treating properly the address space indication 0b11 (ie. 0x3) as meaning 64 bits memory space. This means that it fails to parse addresses for PCI BARs that have this encoding set by the firmware, which happens on some SLOF versions and breaks offb palette handling on Powerstation.

This patch adds support for the power button on future IBM cell blades. It actually doesn't shut down the machine. Instead it exposes an input device /dev/input/event0 to userspace which sends KEY_POWER if power button has been pressed. haldaemon actually recognizes the button, so a plattform independent acpid replacement should handle it correctly.

This patch adds a cpufreq governor that takes the number of running spus into account. It's very similar to the ondemand governor, but not as complex. Instead of hacking spu load into the ondemand governor it might be easier to have cpufreq accepting multiple governors per cpu in future. Don't know if this is the right way, but it would keep the governors simple. Signed-off-by:

DDR2 memory DIMMs on the Axon could be accessed only as one partition when using file system drivers which are using the direct_access() method. This patch enables for such file system drivers to access Axon's DDR2 memory even if it is splitted in several partitions. Signed-off-by:

This reverts commit e3621ee6. This was not the proper fix. As Scott Wood said CONFIG_FS_ENET has nothing to do with the issue. The proper fix is to select PHYLIB for this board.
-
Kumar Gala authored
Its possible to build the phylib as a module, however this breaks the board code because alloc_mdio_bitbang and mdiobus_register are not available if we build as a module. These are needed by the board code since it implements the low level mdio bitbang ops. So we unconditionally select PHYLIB to ensure its built into the kernel if we are building in EP8248E support. Long term we should look at moving the mdio_ops into its own file so it can be built as a module. Signed-off-by: -

This converts the FSL Book-E PTE access and TLB miss handling to match with the recent changes to 44x that introduce support for non-atomic PTE operations in pgtable-ppc32.h and removes write back to the PTE from the TLB miss handlers. In addition, the DSI interrupt code no longer tries to fixup write permission, this is left to generic code, and _PAGE_HWWRITE is gone. Signed-off-by: -

Now that arch/ppc is gone we always define CONFIG_PPC_CPM_NEW_BINDING so we can remove all the code associated with !CONFIG_PPC_CPM_NEW_BINDING. Also fixed some asm/of_platform.h to linux/of_platform.h (and of_device.h) Signed-off-by: -

The old code assumed there was only one, but the 8572 actually has 3. Also, our usual id, 0xe0024520, gets resolved to -1 somewhere, and this was preventing the multiple buses from having different ids. So we only keep the low 20 bits, which have the interesting info, anyway. Signed-off-by:

The ULI "Super South Bridge" contains ISA bridge to the legacy devices, such as Super IO mouse/keyboard/floppy disk controllers, parallel port, i8259 interrupt controller and so on. i8259 is disabled on the MPC8610HPCD, and other peripherals are not traced out. So we use only RTC. Signed-off-by:

- Get rid of uses_fsl_uli_m1575, it does not scale for all cases. Instead, let's explicitly use machine_is() for each fixup. - Factor out MPC8610HPCD quirks to fsl_uli1575, and protect them with machine_is(). One step closer to multiplatform kernels. - Actually use fsl_uli1575 on MPC8610HPCD, so RTC quirk will be applied. - RTC quirk applies to all boards though, so no machine_is() checks. Signed-off-by:

This patch fixes RTC on MPC8572DS boards: dummy read helps only when reading at the end of the bridge's memory (i.e. outside of behind the bridge devices' assigned regions). With this change the quirk also makes RTC work on MPC8610HPCD, so it's unlikely that this will break MPC8641HPCN or MPC8544DS boards. Signed-off-by:

Freescale ships MPC8315E-RDB boards in two variants: 1. With TSEC1 ethernet support and USB UTMI PHY; 2. Without TSEC1 support, but with USB ULPI PHY in addition.

Choosing PCI or not at config time is allowed on some platforms via an if expression in arch/powerpc/Kconfig. To add a new platform with PCI support selectable at config time, you must change the if expression. This patch makes this easier by changing: bool "PCI support" if <long expression> to bool "PCI support" if PPC_PCI_CHOICE and adding select PPC_PCI_CHOICE to all the config nodes that were previously in the PCI if expression. Platforms with unconditional PCI support continue to just select PCI in their config nodes. Signed-off-by:
