* cs5520: disable VDMABartlomiej Zolnierkiewicz2008-05-14
| | | | | | | | | Disable Virtual DMA support for now (it causes system hangs). Thanks to TAKADA Yoshihito for the help with debugging the problem. Reported-by: TAKADA Yoshihito <takada@mbf.nifty.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

| | | | | | | | | | | | | | | | | | * Don't ask to enable no longer existing config options ("Use DMA by default when available" and "Special UDMA Feature"). * PIIX host driver doesn't support Victory66 chipset. * "ide0=cmd640_vlb" -> "cmd640.probe_vlb" * "ide=doubler" -> "gayle.doubler" * Amiga IDE doubler support is a feature for gayle host driver not a separate host driver. * Remove Andre's mail.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix 18 errors and several warnings given by checkpatch.pl: - use of C99 // comments; - trailing whitespace; - 'switch' and 'case' not at the same indentation level; - no space before the open parenthesis of the 'if' and 'switch' statements; - space between function name and open parenthesis (though I have introduced such warnins in some places since the code looks prettier with the spaces); - including <asm/io.h> instead of <linux/io.h>; - line over 80 characters. In addition to these changes, also do the following: - make the arrays in sil_set_pio_mode() 'static', and make the arrays in sil_set_dma_mode() 'static const'; - change the string of the 'if' statements into the 'switch' statement in sil_pata_udma_filter(); - drop the needless '==' operators from the 'if' statements where a condition is a mere bit test; - remove needless initializer for the 'tmp' variable in init_chipset_siimage(); - beautify groups of the variable initializers and assignment operators; - add new line after variable definitions; - remove new line between the comment and the statements it refers to; - remove needless curly braces and parentheses; - fix typos, capitalize acronyms, etc. in the comments...

* siimage: do clocking register posting earlier in setup_mmio_siimage()Bartlomiej Zolnierkiewicz2008-04-28
| | | | | | | | | | | Do clocking register posting earlier in setup_mmio_siimage() to match code in init_chipset_siimage(). This is a preparation for the next patch which merges PCI and MMIO code paths together.

* ide: remove ->INS{W,L} and ->OUTS{W,L} methodsBartlomiej Zolnierkiewicz2008-04-28
| | | | | | | | | | | | | * Use ins{w,l}()/outs{w,l}() and __ide_mm_ins{w,l}()/__ide_mm_outs{w,l}() directly in ata_{in,out}put_data() (by using IDE_HFLAG_MMIO host flag to decide which I/O ops are required). * Remove no longer needed ->INS{W,L} and ->OUTS{W,L} methods (ide-h8300, au1xxx-ide and scc_pata implement their own ->{in,out}put_data methods). There should be no functional changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
* ide: add IDE_HFLAG_MMIO host flag (take 2)Bartlomiej Zolnierkiewicz2008-04-28
| | | | | | | | | | | | | | | | | * Add IDE_HFLAG_MMIO host flag and set it for hosts which use default_hwif_mmiops(). v2: * Fix kernel panic in pmac host driver (',' should be '|'). Thanks to Kamalesh for reporting it + testing the fix and to Andrew for hinting me about the source of the issue.

* ide: merge ->atapi_*put_bytes and ->ata_*put_data methodsBartlomiej Zolnierkiewicz2008-04-28
| | | | | | | | | | | | | | | * Merge ->atapi_{in,out}put_bytes and ->ata_{in,out}put_data methods into new ->{in,out}put_data methods which take number of bytes to transfer as an argument and always do padding. While at it: * Use 'hwif' or 'drive->hwif' instead of 'HWIF(drive)'. There should be no functional changes caused by this patch (all users of ->ata_{in,out}put_data methods were using multiply-of-4 word counts).

* falconide/q40ide: add ->atapi_*put_bytes and ->ata_*put_data methods (take 2)Bartlomiej Zolnierkiewicz2008-04-28
| | | | | | | | | | | | | | | | | | | | | | | * Add ->atapi_{in,out}put_bytes and ->ata_{in,out}put_data methods to falconide and q40ide host drivers (->ata_* methods are implemented on top of ->atapi_* methods so they also do byte-swapping now). * Cleanup atapi_{in,out}put_bytes(). v2: * Add 'struct request *rq' argument to ->ata_{in,out}put_data methods and don't byte-swap disk fs requests (we shouldn't un-swap fs requests because fs itself is stored byte-swapped on the disk) - this is how things were done before the patch (ideally device mapper should be used instead but it would break existing setups and would have some performance impact).
