2014-11-22ARM: mvebu: add MTD_BLOCK to mvebu_v7_defconfigThomas Petazzoni
Since many (most?) mvebu platforms have NAND or SPI flashes, it makes sense to have CONFIG_MTD_BLOCK=y in mvebu_v7_defconfig. The vast majority of the other ARM defconfigs have it enabled, including mvebu_v5_defconfig.

2014-11-22ARM: mvebu: adjust ethernet aliases according to U-Boot requirements for A38xMarcin Wojtas
In order to update MAC address entries in the ethernet nodes in Device Tree both mainline U-Boot and Barebox bootloaders accept the same format of aliases, which is 'ethernetX', where X stands for an interface number. Other platforms in the mainline Linux, that comprise ethernet references in '/aliases' node (like various flavours of imx or sunXi), follow the naming scheme described above. This commit ajusts ethernet aliases of Marvell Armada 38x SoC to be properly recognized by bootloaders' MAC address fixup routines.

2014-11-22ARM: mvebu: remove clock-frequency from Armada 38x SDHCI Device Tree nodeMarcin Wojtas
For proper operation of Armada 38x SDHCI controller proper 'clocks' property is sufficient. Therefore it is not useful to keep an additional 'clock-frequency' property in SDHCI controller node of board-level Device Tree file for Armada 385 DB. This commit gets rid of useless 'clock-frequency' property.

2014-11-22ARM: mvebu: enable no-1-8-v flag for Armada 385 DB SDHCI interfaceMarcin Wojtas
The Marvell Armada 38x SoC's SDHCI interface is capable of using 1.8v voltage, needed for driving "UHS-I" SD cards at their full speed. It is not, however, possible on the DB board. Due to physical connectivity connector supply is tied to 3v and any attempt of changing voltage in order to operate in the fastest UHS modes fails. This patch enables equivalent SDHCI quirk in order to adjust controller operation to system capabilities.

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.

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.

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.

2014-11-22ARM: imx: clean up machine mxc_arch_reset_init_dt reset initJingchang Lu
System restart mechanism has been changed with the introduction of "kernel restart handler call chain support". The imx2 watchdog based restart handler has been moved to the driver, and these restart can be removed from the machine layer. This patch cleans up the device tree version machine reset init with mxc_arch_reset_init_dt and removes corresponding .restart handler, for the .init_machine that can be handled by system default after removing the mxc_arch_reset_init_dt, the .init_machine is also removed.
