      Sample:

      config BAR
      	bool "This is bar"
      	depends on FOO
      
      This will result in following error message:
      error: found recursive dependency: FOO -> BAR -> FOO
      
      And will then exit with exit code equal 1 so make will stop.

      it821x: PIO mode setup fixes · 0e9b4e53
      Bartlomiej Zolnierkiewicz authored
      * limit max PIO mode to PIO4, this driver doesn't support PIO5 and attempt
        to setup PIO5 by it821x_tuneproc() could result in incorrect PIO timings
        + incorrect base clock being set for controller in the passthrough mode
      
      * move code limiting max PIO according to the pair device capabilities from
        config_it821x_chipset_for_pio() to it821x_tuneproc() so the check is also
        applied for mode change requests coming through ->tuneproc and ->speedproc
        interfaces
      
      * set device speed in it821x_tuneproc()
      
      * in it821x_tune_chipset() call it821x_tuneproc() also if the controller is
        in the smart mode (so the check for pair device max PIO is done)
      
      * rename it821x_tuneproc() to it821x_tune_pio(), then add it821x_tuneproc()
        wrapper which does the max PIO mode check;  it worked by the pure luck
        previously, pio[4] and pio_want[4] arrays were used with index == 255
        so random PIO timings and base clock were set for the controller in the
        passthrough mode, thankfully PIO timings and base clock were corrected
        later by config_it821x_chipset_for_pio() call (but it was not called for
        PIO-only devices during resume and for user requested PIO autotuning)
      
      * remove config_it821x_chipset_for_pio() call from config_chipset_for_dma()

      aec62xx: fix PIO/DMA setup issues · 826a1b65
      Sergei Shtylyov authored
      Teach the driver's tuneproc() method to do PIO auto-runing properly since it
      treated 5 instead of 255 as auto-tune request, and also passed the mode limit
      of PIO5 to ide_get_best_pio_mode() despite supporting up to PIO4 only.
      
      While at it, also:
      
      - remove the driver's wrong claim about supporting SWDMA modes;
      
      - stop hooking ide_dma_timeout() method as the handler clearly doesn't fit for
        the task...

      Fold the parts of the ide_dma_end() methods identical to __ide_dma_end() into a
      mere call to it.
      Start using faster versions of the ide_dma_end() and ide_dma_test_irq() methods
      for the PCI0646U and newer chips that have the duplicate interrupt status bits
      in the I/O mapped MRDMODE register, determing what methods to use at the driver
      load time. Do some cleanup/renaming in the "old" ide_dma_test_irq() method too.

      cmd64x: procfs code fixes/cleanups (take 2) · 5826b318
      Sergei Shtylyov authored
      Fix several issues with the driver's procfs output:
      
      - when testing if channel is enabled, the code looks at the "simplex" bits, not
        at the real enable bits -- add #define for the primary channel enable bit;
      
      - UltraDMA modes 0, 1, 3 for slave drive reported incorrectly due to using the
        master drive's clock cycle resolution bit.
      
      While at it, also perform the following cleanups:
      
      - don't print extra newline before the first controller's dump;
      
      - correct the chipset names (from CMDxxx to PCI-xxx)
      
      - don't read from the registers which aren't used for dump;
      
      - better align the table column sizes;
      
      - rework UltraDMA mode dump code;
      
      - remove PIO mode dump code that has never been finished;
      
      - remove the duplicate interrupt status (the MRDMODE register bits mirror those
        those in the CFR and ARTTIM23 registers) and fold the dump into single line;
      
      - correct the style of the ?: operators...

      cmd64x: add/fix enablebits (take 2) · 7accbffd
      Sergei Shtylyov authored
      The IDE core looks at the wrong bit when checking if the secondary channel is
      enabled on PCI0646 -- CNTRL register bit 7 is read-ahead disable, bit 3 is the
      correct one.
      Starting with PCI0646U chip, the primary channel can also be enabled/disabled --
      so, add 'enablebits' initializers to each 'ide_pci_device_t' structure, handling
      the original PCI0646 via adding the init_setup() method and clearing the 'reg'
      field there if necessary...

      cmd64x: interrupt status fixes (take 2) · e51e2528
      Sergei Shtylyov authored
      The driver's ide_dma_test_irq() method was reading the MRDMODE register even on
      PCI0643/6 where it was write-only -- fix this by always reading the "backward-
      compatible" interrupt bits, renaming dma_alt_stat to irq_stat as the interrupt
      status bits are not coupled to DMA.
      In addition, wrong interrupt bit was tested/cleared for the primary channel --
      it's bit 2 in all the chip specs and the driver used bit 1... :-/

      cmd64x: fix multiword and remove single-word DMA support · 60e7a82f
      Sergei Shtylyov authored
      Fix the multiword DMA and drop the single-word DMA support (which nobody will
      miss, I think).  In order to do it, a number of changes was necessary:
      
      - rename program_drive_counts() to program_cycle_times(), pass to it cycle's
        total/active times instead of the clock counts, and convert them into the
        active/recovery clocks there instead of cmd64x_tune_pio() -- this causes
        quantize_timing() to also move;
      
      - contrarywise, move all the code handling the address setup timing into
        cmd64x_tune_pio(), so that setting MWDMA mode wouldn't change address setup;
      
      - remove from the speedproc() method the  bogus code pretending to set the DMA
        timings by twiddling bits in the BMIDE status register, handle setting MWDMA
        by just calling program_cycle_times(); while at it, improve the style of that
        whole switch statement;
      
      - stop fiddling with the DMA capable bits in the speedproc() method -- they do
        not enable DMA, and are properly dealt with by the dma_host_{on,off} methods;
      
      - don't set hwif->swdma_mask in the init_hwif() method anymore.
      
      In addition to those changes, do the following:
      
      - in cmd64x_tune_pio(), when writing to ARTTIM23 register preserve the interrupt
        status bit, eliminate local_irq_{save|restore}() around this code as there's
        *no* actual race with the interrupt handler, and move cmdprintk() to a more
        fitting place -- after ide_get_best_pio_mode() call;
      
      - make {arttim|drwtim}_regs arrays single-dimensional, indexed with drive->dn;
      
      - rename {setup|recovery}_counts[] into more fitting {setup|recovery}_values[];
      
      - in  the speedproc() method, get rid of the duplicate reads/writes from/to the
        UDIDETCRx registers and of the extra variable used to store the transfer mode
        value after filtering,  use another method of determining master/slave drive,
        and cleanup useless parens;
      
      - beautify cmdprintk() output here and there.
      
      While at it, remove meaningless comment about the driver being used only on
      UltraSPARC and long non-relevant RCS tag. :-)

      sl82c105: DMA support code cleanup (take 4) · 688a87d1
      Sergei Shtylyov authored
      Fold the now equivalent code in the ide_dma_check() method into a mere call to
      ide_use_dma().  Make config_for_dma() return non-zero if DMA mode has been set
      and call it from the ide_dma_check() method instead of ide_dma_on().
      Defer writing the DMA timings to the chip registers until DMA is really turned
      on (and do not enable IORDY for DMA).
      Remove unneeded code from the init_hwif() method, improve its overall looks.
      Rename the dma_start(), ide_dma_check(), and ide_dma_lostirq() methods, and
      also use more proper hwif->dma_command, fix printk() and comment in the latter
      one as well.  While at it, cleanup style in several places.
