If the property was not specified then the returned resource had a resource_size(..) == 1, rather than 0. The PCI-E driver checks for 0 so it blindly continues on with a corrupted resource.

Like last time, Renesas sh-mobile is now the platform with the most changes, followed by OMAP and EXYNOS. Two new platforms, TI Keystone and Rockchips RK3xxx are added in this branch, both containing almost no platform specific code at all, since they are using generic subsystem interfaces for clocks, pinctrl, interrupts etc. The device drivers are getting merged through the respective subsystem maintainer trees. One more SoC (u300) is now multiplatform capable and several others (shmobile, exynos, msm, integrator, kirkwood, clps711x) are moving towards that goal with this series but need more work. Also noteworthy is the work on PCI here, which is traditionally part of the SoC specific code. With the changes done by Thomas Petazzoni, we can now more easily have PCI host controller drivers as loadable modules and keep them separate from the platform code in drivers/pci/host.

2013-05-29drivers: bus: add ARM CCI supportLorenzo Pieralisi
On ARM multi-cluster systems coherency between cores running on different clusters is managed by the cache-coherent interconnect (CCI). It allows broadcasting of TLB invalidates and memory barriers and it guarantees cache coherency at system level through snooping of slave interfaces connected to it. This patch enables the basic infrastructure required in Linux to handle and programme the CCI component. Non-local variables used by the CCI management functions called by power down function calls after disabling the cache must be flushed out to main memory in advance, otherwise incoherency of those values may occur if they are sitting in the cache of some other CPU when power down functions execute. Driver code ensures that relevant data structures are flushed from inner and outer caches after the driver probe is completed. CCI slave port resources are linked to set of CPUs through bus masters phandle properties that link the interface resources to masters node in the device tree. Documentation describing the CCI DT bindings is provided with the patch. Signed-off-by: Lorenzo Pieralisi <lorenzo.pieralisi@arm.com> Signed-off-by: Nicolas Pitre <nicolas.pitre@linaro.org>

2013-03-28bus: introduce an Marvell EBU MBus driverThomas Petazzoni
The Marvell EBU SoCs have a configurable physical address space layout: the physical ranges of memory used to address PCI(e) interfaces, NOR flashes, SRAM and various other types of memory are configurable by software, through a mechanism of so-called 'address decoding windows'. This new driver mvebu-mbus consolidates the existing code to address the configuration of these memory ranges, which is spread into mach-mvebu, mach-orion5x, mach-mv78xx0, mach-dove and mach-kirkwood. Following patches convert each Marvell EBU SoC family to use this driver, therefore removing the old code that was configuring the address decoding windows. It is worth mentioning that the MVEBU_MBUS Kconfig option is intentionally added as a blind option. The new driver implements and exports the mv_mbus_dram_info() function, which is used by various Marvell drivers throughout the tree to get access to window configuration parameters that they require. This function is also implemented in arch/arm/plat-orion/addr-map.c, which ultimately gets removed at the end of this patch series. So, in order to preserve bisectability, we want to ensure that *either* this new driver, *or* the legacy code in plat-orion/addr-map.c gets compiled in. By making MVEBU_MBUS a blind option, we are sure that only a platform that does 'select MVEBU_MBUS' will get this new driver compiled in. Therefore, throughout the next patches that convert the Marvell sub-architectures one after the other to this new driver, we add the 'select MVEBU_MBUS' and also ensure to remove plat-orion/addr-map.c from the build for this specific sub-architecture. This ensures that bisectability is preserved. Ealier versions of this driver had a DT binding, but since those were not yet agreed upon, they were removed. The driver still uses of_device_id to find the SoC specific details according to the string passed to mvebu_mbus_init(). The plan is to re-introduce a proper DT binding as a followup set of patches.
