2011-08-05powerpc: Make KVM_GUEST default to nAnton Blanchard
KVM_GUEST adds a 1 MB array to the kernel (kvm_tmp) which grew my kernel enough to cause it to fail to boot. Dynamically allocating or reducing the size of this array is a good idea, but in the meantime I think it makes sense to make KVM_GUEST default to n in order to minimise surprises.

2011-06-27powerpc: introduce the ePAPR embedded hypervisor vmpic driverAshish Kalra
The Freescale ePAPR reference hypervisor provides interrupt controller services via a hypercall interface, instead of emulating the MPIC controller. This is called the VMPIC. The ePAPR "virtual interrupt controller" provides interrupt controller services for external interrupts. External interrupts received by a partition can come from two sources: - Hardware interrupts - hardware interrupts come from external interrupt lines or on-chip I/O devices. - Virtual interrupts - virtual interrupts are generated by the hypervisor as part of some hypervisor service or hypervisor-created virtual device. Both types of interrupts are processed using the same programming model and same set of hypercalls.

2011-05-19powerpc: Add kconfig for muxed smp ipi supportMilton Miller
Compile the new smp ipi mux and demux code only if a platform will make use of it. The new config is selected as required. The new cause_ipi smp op is only available conditionally to point out configs where the select is required; this makes setting the op an immediate fail instead of a deferred unresolved symbol at link. This also creates a new config for power surge powermac upgrade support that can be disabled in expert mode but is default on.

2010-09-10powerpc/5xxx: extend mpc8xxx_gpio driver to support mpc512x gpiosAnatolij Gustschin
The GPIO controller of MPC512x is slightly different from 8xxx GPIO controllers. The register interface is the same except the external interrupt control register. The MPC512x GPIO controller differentiates between four interrupt event types and therefore provides two interrupt control registers, GPICR1 and GPICR2. GPIO[0:15] interrupt event types are configured in GPICR1 register, GPIO[16:31] - in GPICR2 register. This patch adds MPC512x speciffic set_type() callback and updates config file and comments. Additionally the gpio chip registration function is changed to use for_each_matching_node() preventing multiple registration if a node claimes compatibility with another gpio controller type.

2009-10-30powerpc/chrp: Use the same RTAS daemon as pSeriesBenjamin Herrenschmidt
The CHRP code has some fishy timer based code to scan the RTAS event log, which uses a 1KB stack buffer and doesn't even use the results. The pSeries code as a nicer daemon that allows userspace to read the event log and basically uses the same RTAS interface This patch moves rtasd.c out of platform/pseries and makes it usable by CHRP, after removing the old crufty event log mechanism in there. The nvram logging part of the daemon is still only available on 64-bit since the underlying nvram management routines aren't currently shared.

2009-03-11powerpc/kconfig: Kill PPC_MULTIPLATFORMBenjamin Herrenschmidt
CONFIG_PPC_MULTIPLATFORM is a remain of the pre-powerpc days and isn't really meaningful anymore. It was basically equivalent to PPC64 || 6xx. This removes it along with the following changes: - 32-bit platforms that relied on PPC32 && PPC_MULTIPLATFORM now rely on 6xx which is what they want anyway. - A new symbol, PPC_BOOK3S, is defined that represent compliance with the "Server" variant of the architecture. This is set when either 6xx or PPC64 is set and open the door for future BOOK3E 64-bit. - 64-bit platforms that relied on PPC64 && PPC_MULTIPLATFORM now use PPC64 && PPC_BOOK3S - A separate and selectable CONFIG_PPC_OF_BOOT_TRAMPOLINE option is now used to control the use of prom_init.c Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

This commit adds the setup code for booting Linux on AmigaOne G3SE (G3 only), AmigaOne XE and uA1 (G3/G4) desktop computers. These boards were sold by Eyetech and are based on MAI Logic's Teron boards and its Articia S northbridge. The AmigaOne uses U-boot as firmware, which doesn't support a flattened device tree yet. The northbridge has some design flaws, which makes it necessary to use non cacheable memory for DMA operations (CONFIG_NOT_COHERENT_CACHE) and to avoid setting the coherence (M) flag for memory pages.

2008-12-30powerpc: Implement GPIO driver for simple memory-mapped banksAnton Vorontsov
The driver supports very simple GPIO controllers, that is, when a controller provides just a 'data' register. Such controllers may be found in various BCSRs (Board's FPGAs used to control board's switches, LEDs, chip-selects, Ethernet/USB PHY power, etc). So far we support only 1-byte GPIO banks. Support for other widths may be implemented when/if needed. p.s. To avoid "made up" compatible entries (like compatible = "simple-gpio"), boards must call simple_gpiochip_init() to pass the compatible string.

2008-10-13powerpc/QE: move QE_GPIO Kconfig symbol into the platforms/KconfigAnton Vorontsov
Specifying user-selectable option in the qe_lib/Kconfig was a bad idea because the qe_lib/Kconfig is included into the top level Kconfig, and thus the QE_GPIO option appears at the top level menu.

2008-10-13powerpc: make Freescale QE support a selectable Kconfig optionTimur Tabi
Modify the Kconfig so that Freescale QUICC Engine (QE) support is a selectable option, thereby allowing users to compile kernels without any QE support. The drawback is that QE support is now disabled by default on platforms that have a QE, and so a defconfig is needed to enable QE and QE devices (like UCC GETH). Fortunately, all the current relevant defconfigs do that already. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2008-07-16powerpc: pci config cleanupJohn Rigby
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.

2008-01-25[POWERPC] Enable RTC for Ebony and Walnut (v2)David Gibson
This patch extends the Ebony and Walnut platform code to instantiate the existing ds1742 RTC class driver for the DS1743 RTC/NVRAM chip found on both those boards. The patch uses a helper function to scan the device tree and instantiate the appropriate platform_device based on it, so it should be easy to extend for other boards which have mmio mapped RTC chips. Along with this, the device tree binding for the ds1743 chips is tweaked, based on the existing DS1385 OF binding found at: http://playground.sun.com/1275/proposals/Closed/Remanded/Accepted/346-it.txt Although that document covers the NVRAM portion of the chip, whereas here we're interested in the RTC portion, so it's not entirely clear if that's a good model. This implements only RTC class driver support - that is /dev/rtc0, not /dev/rtc, and the low-level get/set time callbacks remain unimplemented. That means in order to get at the clock you will either need a modified version of hwclock which will look at /dev/rtc0, or you'll need to configure udev to symlink rtc0 to rtc.
