* ARM: ixp4xx: Convert to SPARSE_IRQLinus Walleij2019-04-191-0/+2
| | | | | | | | | | This localizes the <mach/irqs.h> header to the mach-ixp4xx directory, removes NR_IRQS and switches IXP4xx over to using SPARSE_IRQ. This is a prerequisite for DT support. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* ARM: PCI: provide a default bus scan implementationRussell King2012-05-131-1/+1
| | | | | | | | | | Most PCI implementations perform simple root bus scanning. Rather than having each group of platforms provide a duplicated bus scan function, provide the PCI configuration ops structure via the hw_pci structure, and call the root bus scanning function from core ARM PCI code.

* ARM: PCI: get rid of pci_std_swizzle()Russell King2012-05-131-1/+0
| | | | | | | | | | | | | | | | | | 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.

* PCI: Make the struct pci_dev * argument of pci_fixup_irqs const.Ralf Baechle2011-07-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Aside of the usual motivation for constification, this function has a history of being abused a hook for interrupt and other fixups so I turned this function const ages ago in the MIPS code but it should be done treewide. Due to function pointer passing in varous places a few other functions had to be constified as well.

| | | | | | | | | | | | Patch from Deepak Saxena Other than interrupt masking purposes, this API is only used when configuring interrupt lines and this patch moves that functionality directly into the ixp4xx_set_irq_type() implementation as board level PCI code should not need to worry about those details.

* [ARM] 3140/1: NSLU2 machine supportAlessandro Zummo2005-11-101-0/+77
Patch from Alessandro Zummo This patch adds support for the LinkSys NSLU2 running with both big and little-endian kernels. The LinkSys NSLU2 is a cost engineered ARM, XScale 420 based system similar to the the Intel IXDP425 evaluation board. It uses the IXP4XX ARCH. While this patch applies independently of other patches the resultant kernel requires further patches to successfully use onboard devices, including the onboard flash. Since these patches are independent of this one they will be submitted separately. A defconfig is not included here because not all of the required drivers are actually in the kernel. We intend to provide one as soon as the patches will be incorporated in mainstream.
