The Motorola PrPMC280 and PrPMC2800 processor modules sit on an F101 or PrPMC2800 baseboard, respectively. There are several variants of each type of processor module which can have different amounts of memory, amounts of FLASH, cpu frequencies, and an mv64360 or an mv64362. The bootwrapper code for that platform reads VPD from an I2C EEPROM to determine the processor module variant. From the variant, the amount of memory, etc. is determined and the device tree is updated accordingly. If the variant cannot be determined (e.g., corrupted VPD or a previously unknown variant), the property values already in the device tree are used. Also, the firmware for those platforms does not completely configure the mv64x60 host bridge so that configuration is done here. Signed-off-by:

Add the device tree source file for the prpmc2800 line of processor PMCs. Several of the property values are updated by the bootwrapper but sane defaults have been chosen in case the bootwrapper can't determine the exact processor board variant. The defaults should allow the kernel to boot despite having non-optimal device tree property values. Signed-off-by:

This patch creates platform_device entries for the Marvell mv64x60 I2C ports, based on information contained in device tree. This driver (like the other mv64x60 drivers) are unusual in that it works on both the MIPS and PowerPC architectures. Because of that, the drivers do not support the normal PowerPC of_platform_bus_type. They support platform_bus_type instead. Signed-off-by:

There are 3 interrupt groups each with its own status/mask registers. We use a separate struct irq_chip for each interrupt group and handle interrupts in two stages or levels: level 1 selects the appropriate struct irq_chip, and level 2 selects individual interrupts within that irq_chip.

Some platforms support a variety processor modules with no method of determining which exact processor module is being used except by examining Vital Product Data (VPD). The modules may have different amounts of memory, clock frequencies, etc. so reading the VPD becomes necessary to correctly set properties in the device tree before its passed to the kernel. Often the VPD is stored in I2C EEPROMs so an I2C driver becomes necessary. This I2C driver is for the I2C controller that's embedded on the Marvel mv64x60 line of host bridges. Signed-off-by:

The mv64x60 host bridge has many windows between its various components (cpu, system memory, ethernet ctlr, MPSC, DMA ctlr, PCI MEM, PCI I/O). Unfortunately, the firmware on some of mv64x60-based platforms do not properly or completely configure those windows (e.g., MPSC->system memory windows not configured or CPU->PCI MEM space not configured). So, the missing configuration needs to be done in either the bootwrapper or in the kernel. To keep the kernel as clean as possible, it is done in the bootwrapper. Note that I/O controller configuration is NOT being done, its only the windows to allow the I/O controllers and other components to access memory, etc. that is being done--drivers assume that their controllers can already access system memory). Table of routines and the windows they configure: mv64x60_config_ctlr_windows() ENET->System Memory MPSC->System Memory IDMA->System Memory mv64x60_config_pci_windows() PCI MEM->System Memory PCI I/O->Bridge's Registers mv64x60_config_cpu2pci_window() CPU->PCI MEM CPU->PCI I/O Signed-off-by:

Add 'zImage.dts' and 'zImage.dts_initrd' build rules that automatically compile and wrap a dts file from arch/powerpc/boot/dts into the zImage file. The resulting zImage will be arch/powerpc/boot/zImage.dts.<platform> and arch/powerpc/boot/zImage.dts_initrd.<platform>, respectively. Having separate rules allows the user to choose whether to include a device tree--and which device tree--at build time. This is useful when one Makefile target builds a zImage that runs on several platforms except for differing device trees. By just setting CONFIG_DEVICE_TREE and running "make zImage.dts" the exact zImage you want is built without Makefile bloat or manually running the wrapper script. The dts file is expected to be arch/powerpc/boot/dts/$(CONFIG_DEVICE_TREE) Signed-off-by:

Greatly simplify the function smp_space_timers. The stolen time calculation (per comment within the code) doesn't need the half-jiffy stagger any more. There isn't an issue with bouncing off global locks, so we really shouldn't need any sort of staggering at all. However, the last_jiffy value still needs to be set. This removes the extra stagger logic, and just sets the values. This change should benefit applications that rely on barrier synchronization, and will help cut down OS jitter.

Today's find is a triggered assertion in msi_free_irqs() when the system doesn't support MSI, in which case arch_setup_msi_irqs() always returns an error. The problem is that when this happens we branch into msi_free_irqs(), to which you added the following assertion loop: list_for_each_entry(entry, &dev->msi_list, list) BUG_ON(irq_has_action(entry->irq)); Well, if arch_setup_msi_irqs() fails, entry->irq will be zero and although that's never assigned to any normal devices we use that IRQ number for the timer interrupt on sparc64 so this assertion triggers. Better to test for zero before doing the irq_has_action() assertion thing. Signed-off-by:

I have a system where I have a simple IDE controller that sits on a local bus without bus master dma capability, and thus no dma_mapping ops defined for the device/bus. pata_platform works great for me, with the exception of using the generic ata_port_start which tries to do a dmam_alloc_coherent. Looks like it doesn't need to allocate a prd table at all, so replace it with a dummy function instead. Signed-off-by:

After certain errors, some devices report complete garbage on IDENTIFY. This can cause ata_dev_read_id() to fail with -EINVAL resulting in immediate disabling of the device. Give the device one last chance after -EINVAL to allow recovery from such situations. As -EINVAL is triggered very rarely, this shouldn't cause any noticeable affect on more common error paths.

It seems the world isn't as frank as we thought and some devices lie about who they are. Fallback to the other IDENTIFY if IDENTIFY is aborted by the device. As this is the strategy used by IDE for a long time, it shouldn't cause too much problem. Signed-off-by:

libata enables SCSI host during ATA host activation which happens after IRQ handler is registered and IRQ is enabled. All ATA ports are in frozen state when IRQ is enabled but frozen ports may raise limited number of IRQs after being frozen - IOW, ->freeze() is not responsible for clearing pending IRQs. During normal operation, the IRQ handler is responsible for clearing spurious IRQs on frozen ports and it usually doesn't require any extra code. Unfortunately, during host initialization, the IRQ handler can end up scheduling EH for a port whose SCSI host isn't initialized yet. This results in OOPS in the SCSI midlayer. This is relatively short window and scheduling EH for probing is the first thing libata does after initialization, so ignoring EH scheduling until initialization is complete solves the problem nicely. This problem was spotted by Berck E. Nash in the following thread. http://thread.gmane.org/gmane.linux.kernel/519412Signed-off-by:

The intention of using port_mask in SFF init helpers was to eventually support exoctic configurations such as combination of legacy and native port on the same controller. This never became actually necessary and the related code always has been subtly broken one way or the other. Now that new init model is in place, there is no reason to make common helpers capable of handling all corner cases. Exotic cases can simply dealt within LLDs as necessary. This patch removes port_mask handling in SFF init helpers. SFF init helpers don't take n_ports argument and interpret it into port_mask anymore. All information is carried via port_info. n_ports argument is dropped and always two ports are allocated. LLD can tell SFF to skip certain port by marking it dummy. Note that SFF code has been treating unuvailable ports this way for a long time until recent breakage fix from Linus and is consistent with how other drivers handle with unavailable ports. This fixes 1-port legacy host handling still broken after the recent native mode fix and simplifies SFF init logic. The following changes are made... * ata_pci_init_native_host() and ata_init_legacy_host() both now try to initialized whatever they can and mark failed ports dummy. They return 0 if any port is successfully initialized. * ata_pci_prepare_native_host() and ata_pci_init_one() now doesn't take n_ports argument. All info should be specified via port_info array. Always two ports are allocated. * ata_pci_init_bmdma() exported to be used by LLDs in exotic cases. * port_info handling in all LLDs are standardized - all port_info arrays are const stack variable named ppi. Unless the second port is different from the first, its port_info is specified as NULL (tells libata that it's identical to the last non-NULL port_info). * pata_hpt37x/hpt3x2n: don't modify static variable directly. Make an on-stack copy instead as ata_piix does. * pata_uli: It has 4 ports instead of 2. Don't use ata_pci_prepare_native_host(). Allocate the host explicitly and use init helpers. It's simple enough. Signed-off-by:
