2008-04-28ide: add ide_pad_transfer() helperBartlomiej Zolnierkiewicz
* Add ide_pad_transfer() helper (which uses ->{in,out}put_data methods internally so the transfer is also padded to drive+host requirements) and use it instead of ide_atapi_{write_zeros,discard_data}(). * Remove no longer needed ide_atapi_{write_zeros,discard_data}().

2008-04-28ide: add ide_execute_pkt_cmd() helperBartlomiej Zolnierkiewicz
Add ide_execute_pkt_cmd() helper for executing PACKET command, then convert ATAPI device drivers to use it. As a nice side-effect this fixes ide-{floppy,tape,scsi} w.r.t. ide_lock taking (ide-cd was OK). Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-04-28ide: always use ->OUTBSYNC method for executing commandsBartlomiej Zolnierkiewicz
Always use ->OUTBSYNC method for executing commands so the posting is done if needed (this affects only pmac and scc_pata host drivers at the moment). Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-04-28ide: merge ->atapi_*put_bytes and ->ata_*put_data methodsBartlomiej Zolnierkiewicz
* 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). Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-04-27ide: add struct ide_io_ports (take 3)Bartlomiej Zolnierkiewicz
* Add struct ide_io_ports and use it instead of `unsigned long io_ports[]` in ide_hwif_t. * Rename io_ports[] in hw_regs_t to io_ports_array[]. * Use un-named union for 'unsigned long io_ports_array[]' and 'struct ide_io_ports io_ports' in hw_regs_t. * Remove IDE_*_OFFSET defines. v2: * scc_pata.c build fix from Stephen Rothwell. v3: * Fix ctl_adrr typo in Sparc-specific part of ns87415.c. (Noticed by Andrew Morton) Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-04-26ide: add struct ide_dma_ops (take 3)Bartlomiej Zolnierkiewicz
Add struct ide_dma_ops and convert core code + drivers to use it. While at it: * Drop "ide_" prefix from ->ide_dma_end and ->ide_dma_test_irq methods. * Drop "ide_" "infixes" from DMA methods. * au1xxx-ide.c: - use auide_dma_{test_irq,end}() directly in auide_dma_timeout() * pdc202xx_old.c: - drop "old_" "infixes" from DMA methods * siimage.c: - add siimage_dma_test_irq() helper - print SATA warning in siimage_init_one() * Remove no longer needed ->init_hwif implementations. v2: * Changes based on review from Sergei: - s/siimage_ide_dma_test_irq/siimage_dma_test_irq/ - s/drive->hwif/hwif/ in idefloppy_pc_intr(). - fix patch description w.r.t. au1xxx-ide changes - fix au1xxx-ide build - fix naming for cmd64*_dma_ops - drop "ide_" and "old_" infixes - s/hpt3xxx_dma_ops/hpt37x_dma_ops/ - s/hpt370x_dma_ops/hpt370_dma_ops/ - use correct DMA ops for HPT302/N, HPT371/N and HPT374 - s/it821x_smart_dma_ops/it821x_pass_through_dma_ops/ v3: * Two bugs slipped in v2 (noticed by Sergei): - use correct DMA ops for HPT374 (for real this time) - handle HPT370/HPT370A properly Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-04-18ide: remove IDE_*_REG macrosBartlomiej Zolnierkiewicz
* Add IDE_{ALTSTATUS,IREASON,BCOUNTL,BCOUNTH}_OFFSET defines. * Remove IDE_*_REG macros - this results in more readable and slightly smaller code.

2008-02-02ide-floppy: remove unused flag PC_ABORTBorislav Petkov
This flag was never being set in the code so remove it. By the way, the code in the second patch was being executed unconditionally, i.e. in case pc->retries > IDEFLOPPY_MAX_PC_RETRIES is true (actually that is the only case when the outer if-test passed), !test_bit(PC_ABORT, &pc->flags) was always true so the comment is now incorrect and has to go.

2008-02-02ide-floppy: merge idefloppy_{input,output}_buffersBorislav Petkov
We merge idefloppy_{input,output}_buffers() into idefloppy_io_buffers() by introducing a 4th arg. called direction. According to its value we atapi_input_bytes() or atapi_output_bytes(). Also, this simplifies the interrupt handler logic a bit. Finally, rename idefloppy_io_buffers() to ide_floppy_io_buffers().

2008-02-02ide-floppy: mv idefloppy_{should_,}report_errorBorislav Petkov
In addition to shortening the function name, move the printk-call into the function thereby saving some code lines. Also, make the function out_of_line since it is not on a performance critical path. Finally, rename the reworked function to ide_floppy..().

2008-02-02ide-floppy: factor out ioctl handlers from idefloppy_ioctl()Borislav Petkov
By passing idefloppy_floppy_t *floppy to the factored out functions, we get rid of (almost) all local vars so stack usage should be at minimum here. Also, we merge idefloppy_begin_format() into idefloppy_format_start() since it is its only user. Also, rename idefloppy_format_start() to idefloppy_format_unit(). Finally, rename the reworked functions to ide_floppy..().

2008-02-02ide-floppy: remove struct idefloppy_capacity_descriptorBorislav Petkov
Also, - remove the accompanying 4 byte idefloppy_capacity_header. - rename functions from idefloppy_... to ide_floppy_... after cleanup. - simplify loop in ide_floppy_get_capacity() by reversing if-test condition logically. - finally, fix white space and checkpatch.pl issues Signed-off-by: Borislav Petkov <bbpetkov@yahoo.de> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-02-02ide-floppy: remove struct idefloppy_capabilities_pageBorislav Petkov
This change is rather temporary and is in preparation of using generic commands as is the case with ide-cd and the uniform cdrom layer (i.e. init_cdrom_command()) However, before this happens, we'll have to remove all typedefs and teach idefloppy_create_mode_sense_cmd() to work directly on u8 buffers. Also, since idefloppy_get_capability_page() was used to read only the sfrp bit, rename the latter so that the name reflects what it does.

2008-02-02ide-floppy: disambiguate function namesBorislav Petkov
There were two almost identical function names in ide-floppy.c, which makes their distinction almost impossible. While ide_floppy_release() cleans up the object after the last reference to it has been dropped, idefloppy_release() is the blkdev .release method from struct block_device_operations which releases that last reference. Rename ide_floppy_release() to idefloppy_cleanup_obj() in order to make its purpose more clear. There should be no functionality change resulting from this patch.
