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.

moved out of line) Patch from Rod Whitby PAGE_SHIFT is undeclared in include/asm-arm/arch-ixp4xx/memory.h, identified by the following kernel compilation error: CC [M] sound/core/memory.o In file included from include/asm/memory.h:27, from include/asm/io.h:28, from sound/core/memory.c:24: include/asm/arch/memory.h: In function `__arch_adjust_zones': include/asm/arch/memory.h:28: error: `PAGE_SHIFT' undeclared (first use in this function) This patch replaces my previous attempt at fixing this problem (Patch 3214/1) and is based on the following feedback: Russell King wrote: > The error you see came up on SA1100.

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.

2006-01-04[ARM] 3192/1: Remove gpio_isr_line_clear() API from IXP4xxDeepak Saxena
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.

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.

2005-08-26[PATCH] arm: fix IXP4xx flash resource rangeDeepak Saxena
We are currently reserving one byte more than actually needed by the flash device and overlapping into the next I/O expansion bus window. This a) causes us to allocate an extra page of VM due to ARM ioremap() alignment code and b) could cause problems if another driver tries to request the next expansion bus window.

2005-07-06[PATCH] ARM: 2792/1: IXP4xx iomap API implementationDeepak Saxena
Patch from Deepak Saxena This patch implements the iomap API for Intel IXP4xx NPU systems. We need to implement our own version of the API functions b/c of the PCI hostbridge does not provide the capability to map PCI I/O space into the CPU's physical memory space. In addition, if a system has more than 64M of PCI memory mapped BARs, PCI memory must also be accessed indirectly. This patch changes the assignment of PCI I/O resources to fall into to 0x0000:0xffff range so that we can trap I/O areas in our ioread/iowrite macros.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
