2008-08-10[ARM] dma-mapping: improve type-safeness of DMA translationsRussell King4-37/+61
OMAP at least gets the return type(s) for the DMA translation functions wrong, which can lead to subtle errors. Avoid this by moving the DMA translation functions to asm/dma-mapping.h, and converting them to inline functions. Fix the OMAP DMA translation macros to use the correct argument and result types. Also, remove the unnecessary casts in dmabounce.c. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2008-08-09[ARM] prevent crashing when too much RAM installedLennert Buytenhek3-0/+71
This patch will truncate and/or ignore memory banks if their kernel direct mappings would (partially) overlap with the vmalloc area or the mappings between the vmalloc area and the address space top, to prevent crashing during early boot if there happens to be more RAM installed than we are expecting. Since the start of the vmalloc area is not at a fixed address (but the vmalloc end address is, via the per-platform VMALLOC_END define), a default area of 128M is reserved for vmalloc mappings, which can be shrunk or enlarged by passing an appropriate vmalloc= command line option as it is done on x86. On a board with a 3:1 user:kernel split, VMALLOC_END at 0xfe000000, two 512M RAM banks and vmalloc=128M (the default), this patch gives: Truncating RAM at 20000000-3fffffff to -35ffffff (vmalloc region overlap). Memory: 512MB 352MB = 864MB total On a board with a 3:1 user:kernel split, VMALLOC_END at 0xfe800000, two 256M RAM banks and vmalloc=768M, this patch gives: Truncating RAM at 00000000-0fffffff to -0e7fffff (vmalloc region overlap).

Since the boot loader apparently sets the SATA LEDs 2-4 to red and the SATA LED can only be red or green (but not both), exporting the red SATA LEDs (which automatically turns them off upon boot) makes the green SATA presence/activity indication visible.

2008-08-08[ARM] Fix SMP booting with non-zero PHYS_OFFSETRussell King1-2/+2
The existing code tries to get the pmd for the temporary page table by doing: pgd = pgd_alloc(&init_mm); pmd = pmd_offset(pgd, PHYS_OFFSET); Since we have a two level page table, pmd_offset() is a no-op, so this just has a casting effect from a pgd to a pmd - the address argument is unused. So this can't work. Normally, we'd do: pgd = pgd_offset(&init_mm, PHYS_OFFSET); ... pmd = pmd_offset(pgd, PHYS_OFFSET); to get the pmd you want. However, pgd_offset() takes the mm_struct, not the (unattached) pgd we just allocated. So, instead use: pgd = pgd_alloc(&init_mm); pmd = pmd_offset(pgd + pgd_index(PHYS_OFFSET), PHYS_OFFSET); Reported-by: Antti P Miettinen <ananaza@iki.fi> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

Structs called at91_nand_data where renamed to atmel_nand_data and configs called *MTD_NAND_AT91* where renamed to *MTD_NAND_ATMEL*. This was unfortunately not done consistently, causing NAND chips not being initialised on several ARM boards. I am aware that the author of the original change did not rename MTD_NAND_AT91_BUSWIDTH to MTD_NAND_ATMEL_BUSWIDTH, for example. All *MTD_NAND_AT91* where renamed to *MTD_NAND_ATMEL* in order to keep naming consistency. This patch was only tested on a MACH_SAM9_L9260, as this is the only ARM board I have to my disposal.

2008-07-29[ARM] pxa: add support for L2 outer cache on XScale3 (attempt 2)Eric Miao3-22/+190
(20072fd0c93349e19527dd2fa9588b4335960e62 lost most of its changes somehow, came from a mbox archive applied with git-am. No idea what happened. This puts back the missing bits. --rmk) The initial patch from Lothar, and Lennert make it into a cleaner one, modified and tested on PXA320 by Eric Miao. This patch moves the L2 cache operations out of proc-xsc3.S into dedicated outer cache support code. CACHE_XSC3L2 can be deselected so no L2 cache specific code will be linked in, and that L2 enable bit will not be set, this applies to the following cases: a. _only_ PXA300/PXA310 support included and no L2 cache wanted b. PXA320 support included, but want L2 be disabled So the enabling of L2 depends on two things: - CACHE_XSC3L2 is selected - and L2 cache is present Where the latter is only a safeguard (previous testing shows it works OK even when this bit is turned on). IXP series of processors with XScale3 cannot disable L2 cache for the moment since they depend on the L2 cache for its coherent memory, so IXP may always select CACHE_XSC3L2. Other L2 relevant bits are always turned on (i.e. the original code enclosed by #if L2_CACHE_ENABLED .. #endif), as they showed no side effects. Specifically, these bits are: - OC bits in TTBASE register (table walk outer cache attributes) - LLR Outer Cache Attributes (OC) in Auxiliary Control Register Signed-off-by: Lothar WaÃ<9f>mann <LW@KARO-electronics.de> Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Signed-off-by: Eric Miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
