[ARM] move include/asm-arm to arch/arm/include/asm

2008-08-02T20:32:35Z

Move platform independent header files to arch/arm/include/asm, leaving those in asm/arch* and asm/plat* alone. Signed-off-by: Russell King

[ARM] Clean up discontigmem support

2006-11-30T22:52:28Z

Most architectures have fairly simple discontiguous memory - a simple set of successive regions each containing some memory. These can be described simply as a log2 of their maximum size, along with the base address of the first region and the number of regions. The base address is already described by PHYS_PFN_OFFSET, and the number of regions via the MAX_NUMNODES and the number of online nodes. If we then supply the log2 of their maximum size, all the other discontigmem macros can move into generic code. There is one exception: lh7a40x seems to have a more complicated setup; this is left alone. Signed-off-by: Russell King

[ARM] 3705/1: add supersection support to ioremap()

2006-07-01T18:58:20Z

Patch from Lennert Buytenhek Analogous to the previous patch that allows ioremap() to use section mappings, this patch allows ioremap() to use supersection mappings. Original patch by Deepak Saxena. Signed-off-by: Lennert Buytenhek Signed-off-by: Russell King

[ARM] Add section support to ioremap

2006-06-29T21:14:30Z

Allow section mappings to be setup using ioremap() and torn down with iounmap(). This requires additional support in the MM context switch to ensure that mappings are properly synchronised when mapped in. Based an original implementation by Deepak Saxena, reworked and ARMv6 support added by rmk. Signed-off-by: Russell King

[ARM] nommu: adjust headers for !MMU ARM systems

2006-06-28T16:59:45Z

Majorily based on Hyok Choi's patches, this fixes up the asm-arm header files for mmuless systems. Over and above Hyok's patches: - nommu.h merged into mmu.h (it's only a structure) - nommu_context.h is essentially the same as mmu_context.h, but without the MM switching code. so there's no point having separate files. Also, in memory.h, there's no point #ifndef'ing PHYS_OFFSET and END_MEM - both CONFIG_DRAM_BASE and CONFIG_DRAM_SIZE will always be set by the configuration scripts. Other files have minor formatting changes, but are essentially the same. Hyok's original patches were signed off thusly: Signed-off-by: Hyok S. Choi Signed-off-by: Russell King

[ARM] arm's arch_local_page_offset() fix against 2.6.17-rc1

2006-04-04T15:06:00Z

This patch fixes arch_local_page_offset(pfn,nid) in arm. This new one (added by unify_pfn_to_page patches) is obviously buggy. This macro calculate page offset in a node. Note: about LOCAL_MAP_NR() comment in arm's sub-archs says... /* * Given a kaddr, LOCAL_MAP_NR finds the owning node of the memory * and returns the index corresponding to the appropriate page in the * node's mem_map. */ but LOCAL_MAP_NR() is designed to be able to take both paddr and kaddr. In this case, paddr is better. Signed-off-by: KAMEZAWA Hiroyuki Signed-off-by: Russell King

[ARM] 3439/2: xsc3: add I/O coherency support

2006-04-01T23:07:39Z

Patch from Lennert Buytenhek This patch adds support for the I/O coherent cache available on the xsc3. The approach is to provide a simple API to determine whether the chipset supports coherency by calling arch_is_coherent() and then setting the appropriate system memory PTE and PMD bits. In addition, we call this API on dma_alloc_coherent() and dma_map_single() calls. A generic version exists that will compile out all the coherency-related code that is not needed on the majority of ARM systems. Note that we do not check for coherency in the dma_alloc_writecombine() function as that still requires a special PTE setting. We also don't touch dma_mmap_coherent() as that is a special ARM-only API that is by definition only used on non-coherent system.
