Since commit 0536bdf33faf (ARM: move iotable mappings within the vmalloc region), the Cavium CNS3xxx cannot boot anymore. This is caused by the pre-defined iotable mappings is not in the vmalloc region.

2013-03-15ARM: cns3xxx: initial DT supportArnd Bergmann3-3/+125
This adds very minimal support for booting cns3xxx using a device tree. It should support the same devices that cns3420vb provides but gets them from the DT. All devices that don't have their own binding are probed through auxdata. This is completely untested and likely incomplete. Booting through ATAGS is made optional, so it can be turned off by anybody who has a DTB file. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

This patch (as1623) removes the ehci_port_power() routine and all the places that call it. There's no reason for ehci-hcd to change the port power settings; the hub driver takes care of all that stuff. There is one exception: When the controller is resumed from hibernation or following a loss of power, the ports that are supposed to be handed over to a companion controller must be powered on first. Otherwise the handover won't work. This process is not visible to the hub driver, so it has to be handled in ehci-hcd.

This patch converts the cns3xxx platform to use the ohci-platform driver which is now suitable for use. A previous patch converted the cns3xxx platform to use the ehci-platform driver, and thus introduced the need to have power_{on,off} callbacks. Since both the EHCI and OHCI platform drivers use the same same power_{on,off} callbacks now, rename them to cns3xx_usb_power_{on,off} to show that they are shared.

Most PCI implementations use the standard PCI swizzle function, which handles the well defined behaviour of PCI-to-PCI bridges which can be found on cards (eg, four port ethernet cards.) Rather than having almost every platform specify the standard swizzle function, make this the default when no swizzle function is supplied. Therefore, a swizzle function only needs to be provided when there is something exceptional which needs to be handled. This gets rid of the swizzle initializer from 47 files, and leaves us with just two platforms specifying a swizzle function: ARM Integrator and Chalice CATS.

2012-01-07arm/PCI: convert to pci_scan_root_bus() for correct root bus resourcesBjorn Helgaas1-4/+4
Convert from pci_scan_bus() to pci_scan_root_bus() and remove root bus resource fixups. This fixes the problem of "early" and "header" quirks seeing incorrect root bus resources.

2012-01-05ARM: restart: remove the now empty arch_reset()Russell King1-4/+0
Remove the now empty arch_reset() from all the mach/system.h includes, and remove its callsite. Remove arm_machine_restart() as this function no longer does anything useful. For samsung platforms, remove the include of mach/system-reset.h and plat/system-reset.h from their respective mach/system.h headers as these just define their arch_reset functions. As a result, the s3c2410 and plat-samsung system-reset.h files are no longer referenced, so remove these files entirely.

2011-10-17ARM: 7022/1: allow to detect conflicting zreladdrsSascha Hauer1-1/+1
Boards used to specify zreladdr in their Makefile.boot with zreladdr-y := x, so conflicting zreladdrs were silently overwritten. This patch changes this to zreladdr-y += x, so that we end up with multiple words in zreladdr in such a case. We can detect this later and complain if necessary.

2011-09-26ARM: add an extra temp register to the low level debugging addruart macroNicolas Pitre1-1/+1
Some platforms (like OMAP not to name it) are doing rather complicated hacks just to determine the base UART address to use. Let's give their addruart macro some slack by providing an extra work register which will allow for much needed cleanups. This is basically a no-op as this commit is only adding the extra argument to the macro but no one is using it yet.
