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 bootwrapper requires a serial driver to allow cmdline editing and information reporting on the console. This driver is required by platforms that boot a zImage and use the MPSC for the console. 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. Boot tested across the board (G5,power3,power4,power5,970mp blade). Signed-off-by:

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:
