This series introduces to Barebox the streaming DMA ops and implements them for the ARM architecture. 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 Regards, Lucas Lucas Stach (24): usb: gadget: include common.h in header 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 | 49 +++++++++++++++++++++++------------ arch/arm/include/asm/dma.h | 30 ++++++++++++++++++++- arch/arm/include/asm/io.h | 15 +++++++++++ arch/arm/include/asm/mmu.h | 45 -------------------------------- arch/arm/mach-bcm2835/mbox.c | 8 +++--- drivers/ata/ahci.c | 14 +++++++--- drivers/dma/apbh_dma.c | 2 +- drivers/mci/Kconfig | 2 +- drivers/mci/dw_mmc.c | 25 +++++++++--------- drivers/mci/imx-esdhc.c | 28 ++++++++++++-------- drivers/mci/tegra-sdmmc.c | 26 ++++++++++--------- drivers/mtd/nand/nand_mxs.c | 2 +- drivers/net/Kconfig | 1 + drivers/net/altera_tse.c | 1 + drivers/net/arc_emac.c | 17 +++++++----- drivers/net/at91_ether.c | 11 ++++++-- drivers/net/cpsw.c | 11 +++++--- drivers/net/davinci_emac.c | 9 ++++--- drivers/net/designware.c | 20 ++++++++------ drivers/net/fec_imx.c | 14 +++++++--- drivers/net/macb.c | 9 +++++-- drivers/net/mvneta.c | 1 + drivers/net/orion-gbe.c | 14 ++++++---- drivers/net/rtl8139.c | 1 + drivers/net/rtl8169.c | 31 ++++++++++------------ drivers/net/xgmac.c | 12 ++++++--- drivers/spi/mxs_spi.c | 1 - drivers/usb/gadget/fsl_udc.c | 11 +++++--- drivers/usb/host/ehci-hcd.c | 9 ++++--- drivers/usb/host/ohci-hcd.c | 11 +++++--- drivers/usb/host/xhci-hcd.c | 2 +- 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 | 2 +- drivers/video/imx-ipu-fb.c | 1 + drivers/video/imx-ipu-v3/ipu-common.c | 1 - drivers/video/imx-ipu-v3/ipufb.c | 2 +- drivers/video/omap.c | 1 + drivers/video/pxa.c | 2 +- include/dma-dir.h | 6 +++++ include/dma.h | 11 ++++++++ include/usb/gadget.h | 1 + 43 files changed, 281 insertions(+), 181 deletions(-) create mode 100644 include/dma-dir.h -- 2.1.0 _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
