2006-11-03[ARM] 3918/1: ixp4xx irq-chip reworkKevin Hilman
This is a rework of the ixp4xx irq_chip implementation. The use of two irq_chip structures and potentially switching between them is a violation of the intended use of the IRQ framework. The current implementation does not work with current in-kernel spinlock debugging or lockdep due to lock recursion problems caused by calling set_irq_chip/handler from within the chip's set_irq_type(). This patch goes back to using one irq_chip structure and handling the differences between edge/level, normal/GPIO interrupts inside the ack/mask/unmask routines themselves.

The NSLU2 has four LED indicators, which are the only form of output for an unmodified device - there is no keyboard or display on an NSLU2.

2006-04-30[ARM] 3487/1: IXP4xx: Support non-PCI systemsDeepak Saxena
Patch from Deepak Saxena This patch allows for the addition of IXP4xx systems that do not make use of the PCI interface by moving the CONFIG_PCI symbol selection to be platform-specific instead of for all of IXP4xx. If at least one machine with PCI support is built, the PCI code will be compiled in, but when building !PCI, this will drastically shrink the kernel size.

2006-04-20[ARM] 3480/1: ixp4xx: fix irq2gpio array typeLennert Buytenhek
Patch from Lennert Buytenhek The irq2gpio array was recently converted from an array of ints to an array of chars (by patch 3368/1.) However, this array contains elements that are -1, and on ARM, the char type is unsigned by default, so this patch broke the GPIO check in ixp4xx_set_irq_type.

2006-01-05[ARM] 3226/1: IXP4xx runtime expansion bus window size configurationDeepak Saxena
Patch from Deepak Saxena The expansion bus on the IXP46x NPU can be configured for either 32MiB or 16MiB windows and changing the configuration causes the base address for each chip select for each region to change. Because of this, we cannot hardcode the physical base as we currently do. This patch checks the expansion bus configuration registers at runtime to determine the appropriate window size. Note that this requires that the bootloader already configured the device sizes appropriately, but I feel that is valid assumption to make as the bootloader must configure and access the flash window, the output display (LCD, LEDs, etc) window, and other expansion bus devices.

2006-01-04[ARM] 3215/1: Iomega NAS 100d (MACH_NAS100D) machine supportRod Whitby
Patch from Rod Whitby This patch adds support for a new arm/ixp4xx machine - the Iomega NAS 100d network attached storage product. The NAS100D is a consumer device containing a 266MHz Intel IXP420 processor, 16MB of flash, 64MB of RAM, a 160Gb internal IDE hard disk, and 802.11b/g wireless on an Atheros mini-PCI card. Work on porting the latest 2.6.x kernel to this device is being done by the NSLU2-Linux project (the same team who maintains the port to the Linksys NSLU2 device). In particular, the majority of this patch was authored by Alessandro Zummo, based on the work done for MACH_NSLU2 support by the NSLU2-Linux core team of developers. MACH_NAS100D (as implemented by this patch) can be enabled in jumbo ixp4xx kernels without any affect on the other machines supported by that kernel. This patch applies cleanly against 2.6.15-rc7 and should be trivial to apply to later kernel versions. It does not depend upon any other patches.

2005-11-10[ARM] 3140/1: NSLU2 machine supportAlessandro Zummo
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.

2005-11-06[ARM] 3089/1: ixp4xx AHB/PCI endianness fixAlessandro Zummo
Patch from Alessandro Zummo This patch fixes AHB/PCI endianness problems when the processor is in little-endian mode. The patch configures the CSR register closely following the directives in [1], paragraph 4.1, page 19. According to the considerations in [1], page 11, while the AHB bus supports both endian modes, on the IXP4XX it always uses big-endian. The PCI bus is connected to the South AHB. A wrong setting in the CSR register will thus cause a malfunctional PCI bus. A schematic diagram of the bus interconnections on the IXP4XX can be found in [1], page 18. The patch has been verified to work on the NSLU2 in both LE and BE modes. The author is Peter Korsgaard.

2005-09-18[ARM] 2917/1: Make IXP4xx mach_desc's depend on config optionsDeepak Saxena
Patch from Deepak Saxena Building a kernel for IXDP425 currently includes the machine descriptors for IXDP465 and PRPMC1100 even if those machines are not configured. This means we can build a kernel that boots on those machines even though the machine_is_xxx() macro will always return 0 and other bits such as PCI won't be compiled in. This can lead to many wasted hours wondering what you have done to your kernel to make it randomly crash thus requireing large quantities of beer to be consumed. While I am all for consumption of large quantities of beer, there are better reasons to do so then stupid kernel bugs.

2005-09-08[SERIAL] Use an enum for serial8250 platform device IDsRussell King
Rather than hard-coding the platform device IDs, enumerate them. We don't particularly care about the actual ID we get, just as long as they're unique. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
