This commit migrates the mach-orion5x platforms to use the mvebu-mbus driver and therefore removes the Orion5x-specific addr-map code. The dove_init_early() function now initializes the mvebu-mbus driver by calling mvebu_mbus_init(). We also convert a number of orion5x_setup_xyz_win() calls to the appropriate mvebu_mbus_add_window() calls, as each board was doing its own setup for the NOR window or other devices. Ultimately, those devices will be probed from the DT. The common address decoding windows are now registered in the orion5x_setup_wins() function. It is worth noting that the four PCIe address decoding windows will ultimately no longer have to be registered here: it will be done automatically by the PCIe driver once Dove has been migrated to use the upcoming mvebu PCIe driver.

The changes needed to migrate the mach-mvebu (Armada 370 and Armada XP) to the mvebu-mbus driver are fairly minimal, since not many devices currently supported on those SoCs use address decoding windows. The only one being the BootROM window, used to bring up secondary CPUs. However, this BootROM window needed for SMP brings an important requirement: the mvebu-mbus driver must be initialized at the ->early_init() time, otherwise the BootROM window cannot be setup early enough to be ready before the secondary CPUs are started.

2013-04-10arm: mvebu: Fix the irq map function in SMP modeGregory CLEMENT1-11/+5
This patch fix the regression introduced by the commit 3202bf0157ccb "arm: mvebu: Improve the SMP support of the interrupt controller": GPIO IRQ were no longer delivered to the CPUs. To be delivered to a CPU an interrupt must be enabled at CPU level and at interrupt source level. Before the offending patch, all the interrupts were enabled at source level during map() function. Mask() and unmask() was done by handling the per-CPU part. It was fine when running in UP with only one CPU. The offending patch added support for SMP, in this case mask() and unmask() was done by handling the interrupt source level part. The per-CPU level part was handled by the affinity API to select the CPU which will receive the interrupt. (Due to some hardware limitation only one CPU at a time can received a given interrupt). For "normal" interrupt __setup_irq() was called when an irq was registered. irq_set_affinity() is called from this function, which enabled the interrupt on one of the CPUs. Whereas for GPIO IRQ which were chained interrupts, the irq_set_affinity() was never called and none of the CPUs was selected to receive the interrupt. With this patch all the interrupt are enable on the current CPU during map() function. Enabling the interrupts on a CPU doesn't depend anymore on irq_set_affinity() and then the chained irq are not anymore a special case. However the CPU which will receive the irq can still be modify later using irq_set_affinity(). Tested with Mirabox (A370) and Openblocks AX3 (AXP), rootfs mounted over NFS, compiled with CONFIG_SMP=y/N.

2013-03-28ARM: Kirkwood: fix unused mvsdio gpio pinsSebastian Hesselbarth3-0/+4
mvsdio_platform_data allows to pass card detect and write protect gpio numbers to the driver. Some kirkwood boards don't use both pins as they are not connected, and don't set the corresponding value in platform_data. This will leave the unset values in platform_data initialized as 0, which is in fact a valid gpio pin. mvsdio will grab that pin and configure it as gpio, which in turn breaks nand controller as mpp0 also carries nand_io2. This patch fixes the above by initializing unused gpio functions in the platform_data with an invalid (-1) value.

2013-03-28arm: mvebu: Use local interrupt only for the timer 0Gregory CLEMENT1-3/+5
The commit 3a6f08a37 "arm: mvebu: Add support for local interrupt", managed the 28th first interrupts as local interrupt to match the hardware specification. Among these interrupts there are the Gigabits Ethernet ones used by the mvneta driver. Unfortunately the state of the percpu_irq API prevents the driver to use it. Indeed the interrupts have to be freed when the .stop() function is called. As the free_percpu_irq() function don't disable the interrupt line, we have to do it on each CPU before calling this. The function disable_percpu_irq() only disable the percpu on the current CPU and there is no function which allows to disable a percpu irq on a given CPU. Waiting for the extension of the percpu_irq API, this fix allows to use again the mvneta driver.

2013-03-20sparc: remove unused "config BITS"Paul Bolle1-6/+0
sparc's asm/module.h got removed in commit 786d35d45cc40b2a51a18f73e14e135d47fdced7 ("Make most arch asm/module.h files use asm-generic/module.h"). That removed the only two uses of this Kconfig symbol. So we can remove its entry too. > >From arch/sparc/Makefile: > ifeq ($(CONFIG_SPARC32),y) > [...] > > [...] > export BITS := 32 > [...] > > else > [...] > > [...] > export BITS := 64 > [...] > > So $(BITS) is set depending on whether CONFIG_SPARC32 is set or not. > Using $(BITS) in sparc's Makefiles is not using CONFIG_BITS. That > doesn't count as usage of "config BITS". Signed-off-by: Paul Bolle <pebolle@tiscali.nl> Acked-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
