2014-11-22ARM: mvebu: re-enable SDHCI driver for Armada 38x SoC in v7 defconfigMarcin Wojtas

2014-11-22ARM: mvebu: Implement the CPU hotplug support for the Armada 38x SoCsGregory CLEMENT
This commit implements the CPU hotplug support for the Marvell Armada 38x platform. Similarly to what was done for the Armada XP, this commit: * Implements the ->cpu_die() function of SMP operations by calling armada_38x_do_cpu_suspend() to enter the deep idle state for CPUs going offline. * Implements a dummy ->cpu_kill() function, simply needed for the kernel to know we have CPU hotplug support. * The mvebu_cortex_a9_boot_secondary() function makes sure to wake up the CPU if waiting in deep idle state by sending an IPI before deasserting the CPUs from reset. This is because mvebu_cortex_a9_boot_secondary() is now used in two different situations: for the initial boot of secondary CPUs (where CPU reset deassert is used to wake up CPUs) and for CPU hotplug (where an IPI is used to take CPU out of deep idle). * At boot time, we exit from the idle state in the ->smp_secondary_init() hook. This commit has been tested using CPU hotplug through sysfs (/sys/devices/system/cpu/cpuX/online) and using kexec.

This patch removes the unneeded include of the armada-370-xp.h header. It also moves some declarations from this file into more accurate places. Finally, it also adds a comment explaining that we can't remove yet the smp field in the dt machine struct due to backward compatibly of the device tree. In a few releases, when the old device tree will be obsolete, we will be able to remove the smp field and then the armada-370-xp.h header.

This reverts commit 5ab5afd8ba83 ("ARM: mvebu: implement Armada 375 coherency workaround"), since we are removing the support for the very early Z1 revision of the Armada 375 SoC. This commit is an exact revert, with two exceptions: - minor adaptations needed due to other changes that have taken place in coherency.c since the original commit - keep the definition of pr_fmt.

2014-11-22ARM: mvebu: disable I/O coherency on non-SMP situations on Armada 370/375/38x/XPThomas Petazzoni
Enabling the hardware I/O coherency on Armada 370, Armada 375, Armada 38x and Armada XP requires a certain number of conditions: - On Armada 370, the cache policy must be set to write-allocate. - On Armada 375, 38x and XP, the cache policy must be set to write-allocate, the pages must be mapped with the shareable attribute, and the SMP bit must be set Currently, on Armada XP, when CONFIG_SMP is enabled, those conditions are met. However, when Armada XP is used in a !CONFIG_SMP kernel, none of these conditions are met. With Armada 370, the situation is worse: since the processor is single core, regardless of whether CONFIG_SMP or !CONFIG_SMP is used, the cache policy will be set to write-back by the kernel and not write-allocate. Since solving this problem turns out to be quite complicated, and we don't want to let users with a mainline kernel known to have infrequent but existing data corruptions, this commit proposes to simply disable hardware I/O coherency in situations where it is known not to work. And basically, the is_smp() function of the kernel tells us whether it is OK to enable hardware I/O coherency or not, so this commit slightly refactors the coherency_type() function to return COHERENCY_FABRIC_TYPE_NONE when is_smp() is false, or the appropriate type of the coherency fabric in the other case. Thanks to this, the I/O coherency fabric will no longer be used at all in !CONFIG_SMP configurations. It will continue to be used in CONFIG_SMP configurations on Armada XP, Armada 375 and Armada 38x (which are multiple cores processors), but will no longer be used on Armada 370 (which is a single core processor). In the process, it simplifies the implementation of the coherency_type() function, and adds a missing call to of_node_put().

2014-11-22ARM: mvebu: make the coherency_ll.S functions work with no coherency fabricThomas Petazzoni
The ll_add_cpu_to_smp_group(), ll_enable_coherency() and ll_disable_coherency() are used on Armada XP to control the coherency fabric. However, they make the assumption that the coherency fabric is always available, which is currently a correct assumption but will no longer be true with a followup commit that disables the usage of the coherency fabric when the conditions are not met to use it. Therefore, this commit modifies those functions so that they check the return value of ll_get_coherency_base(), and if the return value is 0, they simply return without configuring anything in the coherency fabric. The ll_get_coherency_base() function is also modified to properly return 0 when the function is called with the MMU disabled. In this case, it normally returns the physical address of the coherency fabric, but we now check if the virtual address is 0, and if that's case, return a physical address of 0 to indicate that the coherency fabric is not enabled.

2014-11-21ARM/PCI: Save MSI controller in pci_sys_dataYijing Wang
Currently ARM associates an MSI controller with a PCI bus by defining pcibios_add_bus() and using it to call a struct hw_pci.add_bus() method. That method sets the struct pci_bus "msi" member. That's unwieldy and unnecessarily couples MSI with the PCI enumeration code. On ARM, all devices under the same PCI host bridge share an MSI controller, so add an msi_controller pointer to the struct pci_sys_data and implement pcibios_msi_controller() to retrieve it. This is a step toward moving the msi_controller pointer into the generic struct pci_host_bridge.

Correct suspend/resume functions to also use c1, c0, 1. The issue was primarily noticed thanks to qemu reporing "unsupported instruction" on the pxa suspend path.
