This fixes the regression caused by the commit 6fee48cd ("dma-mapping: arm: use generic pci_set_dma_mask and pci_set_consistent_dma_mask"). ARM needs to clip the dma coherent mask for dmabounce devices. This restores the old trick. Note that strictly speaking, the DMA API doesn't allow architectures to do such but I'm not sure it's worth adding the new API to set the dma mask that allows architectures to clip it.

IXP4xx CPUs can indirectly access the whole 4 GB PCI MMIO address space (using the non-prefetch registers). Previously the available space depended on the CPU variant, since one of the IXP43x platforms needed more than the usual 128 MB. 1 GB should be enough for everyone, and if not, we can trivially increase it.

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.

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.

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.

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!
