      sata_rcar: fix interrupt handling · 52a2a108
      Sergei Shtylyov authored
      The driver's interrupt handling code is too picky in deciding whether it should
      handle an interrupt or not which causes completely unneeded spurious interrupts.
      Thus make sata_rcar_{ata|serr}_interrupt() *void*; add ATA status register read
      to sata_rcar_ata_interrupt() to clear an unexpected ATA interrupt -- it doesn't
      get cleared by writing to the SATAINTSTAT register in the interrupt mode we use.
      
      Also, in sata_rcar_ata_interrupt() we should check SATAINTSTAT register only for
      enabled interrupts and we should clear  only those interrupts  that we have read
      as active first time around, because else we have  a  race and risk clearing  an
      interrupt that  can  occur between read  and write of the  SATAINTSTAT  register
      and never registering it...

      sata_rcar: clear STOP bit in bmdma_start() method · df7e131f
      Sergei Shtylyov authored
      Iff bmdma_setup() has to stop a DMA transfer before starting a new
      one, then the STOP bit in the ATAPI_CONTROL1 register will remain set
      (it's only cleared when setting the START bit to 1) and then
      bmdma_start() method will set both START and STOP bits simultaneously
      which should abort the transfer being just started.  Avoid that by
      explicitly clearing the STOP bit in bmdma_start() method (in this case
      it will be ignored on write).

      libata: make ata_exec_internal_sg honor DMADIR · e771451c
      Vincent Pelletier authored
      libata honors DMADIR for regular commands, but not for internal commands
      used (among other) during device initialisation.
      
      This makes SATA-host-to-PATA-device bridges based on Silicon Image SiL3611
      (such as "Abit Serillel 2") end up disabled when used with an ATAPI device
      after a few tries.
      
      Log output of the bridge being hot-plugged with an ATAPI drive:

        I based this off of the last patch you took from me that fixed the
