This will make it a lot easier to get common cache maintenance operations for all architectures and in turn allows for wider reuse of driver across architectures. I've tested this on a Tegra124 which is known to fall over in all sorts of funny ways if cache maintenance is broken. No odd behavior spotted. The series is bisect-clean and I've compile tested it on some defconfigs, but please go wild and TEST. I'll take any complaints. Changes since RFT: - rebased to current master - now compile tested on all ARM defconfigs - fixed a few compile errors by reordering stuff in patches - A few more words in commit logs Changes since v1: - compile tested on MIPS and NIOS - sync prototypes of the dma_coherent fucntion across all arches - introduce DMA_ADDRESS_BROKEN in drivers that need fixing for arches without 1:1 virt:phys mapping Regards, Lucas Lucas Stach (27): usb: gadget: include common.h in header NIOS2: use dma_addr_t in dma_alloc_coherent MIPS: change dma_alloc/free_coherent to common prototypes ARM: change dma_alloc/free_coherent to match other architectures ARM: move virt<->phys translation to io.h dma: add streaming DMA ops ARM: move DMA alloc functions to dma.h ARM: implement streaming DMA ops AHCI: convert to streaming DMA ops MCI: dw-mmc: convert to streaming DMA ops MCI: imx: convert to streaming DMA ops MCI: tegra-sdmmc: convert to streaming DMA ops net: arc-emac: convert to streaming DMA ops net: cpsw: convert to streaming DMA ops net: at91_ether: convert to streaming DMA ops net: davinci_emac: convert to streaming DMA ops net: designware: convert to streaming DMA ops net: fec: convert to streaming DMA ops net: macb: convert to streaming DMA ops net: orion-gbe: convert to streaming DMA ops net: rtl8169: convert to streaming DMA ops net: xgmac: convert to streaming DMA ops usb: gadget: fsl_udc: convert to streaming DMA ops usb: host: ehci: convert to streaming DMA ops usb: host: ohci: convert to streaming DMA ops ARM: bcm2835: mbox: convert to streaming DMA ops ARM: MMU: unexport cache maintenance functions arch/arm/cpu/mmu.c | 55 +++++++++++++++++++++++------------ arch/arm/include/asm/dma.h | 35 +++++++++++++++++++++- arch/arm/include/asm/io.h | 15 ++++++++++ arch/arm/include/asm/mmu.h | 45 ---------------------------- arch/arm/mach-bcm2835/mbox.c | 8 +++-- arch/mips/include/asm/dma-mapping.h | 6 ++-- arch/mips/include/asm/dma.h | 2 +- arch/nios2/include/asm/dma-mapping.h | 13 +++++---- arch/nios2/include/asm/types.h | 2 ++ drivers/ata/ahci.c | 29 ++++++++++++------ drivers/dma/apbh_dma.c | 5 ++-- drivers/mci/Kconfig | 2 +- drivers/mci/dw_mmc.c | 28 +++++++++--------- drivers/mci/imx-esdhc.c | 28 +++++++++++------- drivers/mci/tegra-sdmmc.c | 26 +++++++++-------- drivers/mtd/nand/nand_mxs.c | 7 +++-- drivers/net/Kconfig | 1 + drivers/net/altera_tse.c | 3 +- drivers/net/arc_emac.c | 23 ++++++++++----- drivers/net/at91_ether.c | 17 ++++++++--- drivers/net/cpsw.c | 11 ++++--- drivers/net/davinci_emac.c | 9 +++--- drivers/net/designware.c | 26 ++++++++++------- drivers/net/fec_imx.c | 18 ++++++++---- drivers/net/macb.c | 19 ++++++++---- drivers/net/mvneta.c | 7 +++-- drivers/net/orion-gbe.c | 20 ++++++++----- drivers/net/rtl8139.c | 1 + drivers/net/rtl8169.c | 35 ++++++++++------------ drivers/net/xgmac.c | 20 +++++++++---- drivers/spi/mxs_spi.c | 1 - drivers/usb/gadget/fsl_udc.c | 18 +++++++----- drivers/usb/host/ehci-hcd.c | 15 ++++++---- drivers/usb/host/ohci-hcd.c | 20 ++++++++----- drivers/usb/host/xhci-hcd.c | 8 ++--- drivers/usb/host/xhci-hub.c | 1 - drivers/video/atmel_hlcdfb.c | 1 - drivers/video/atmel_lcdfb.c | 1 - drivers/video/atmel_lcdfb_core.c | 7 +++-- drivers/video/imx-ipu-fb.c | 4 ++- drivers/video/imx-ipu-v3/ipu-common.c | 1 - drivers/video/imx-ipu-v3/ipufb.c | 5 ++-- drivers/video/omap.c | 7 +++-- drivers/video/pxa.c | 9 +++--- include/dma-dir.h | 6 ++++ include/dma.h | 13 +++++++++ include/usb/gadget.h | 1 + 47 files changed, 389 insertions(+), 245 deletions(-) create mode 100644 include/dma-dir.h -- 2.1.0 _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
