* Remove no longer used ->INW and ->OUTW methods. While at it: * scc_pata.c: scc_ide_{out,in}w() is called only in scc_tf_{load,read}() so inline it there. Signed-off-by: NBartlomiej Zolnierkiewicz <bzolnier@gmail.com>

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: NBartlomiej Zolnierkiewicz <bzolnier@gmail.com>

Add sil_iowrite{8,16,32}() and sil_ioread{8,16}() helpers, then use them to merge code accessing configuration registers through PCI and MMIO together. [ because of this SATA initialization bits from setup_mmio_siimage() are moved to init_chipset_siimage() ] This also cuts code size a bit: text data bss dec hex filename 4437 164 0 4601 11f9 drivers/ide/pci/siimage.o.before 3979 164 0 4143 102f drivers/ide/pci/siimage.o.after While at it: * Use I/O ops directly instead of using ->IN{B,W} and ->OUT{B,W}. * Fixup CodingStyle in setup_mmio_siimage(). * Rename 'tmpbyte' variable to 'tmp' in init_chipset_siimage().

* 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).

* 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)'.

* 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).

Since both the IDE interface and SMC 91C111 Ethernet chip are on-board devices, not SOC devices, move the platform device registration form the common to the board specific code. While at it, remove semicolon (which didn't break compilation only by chance) from the AU1XXX_ATA_DDMA_REQ macro and do some renaming: - change 'au1200_ide0_' variable name prefix to the mere 'ide_'; - change 'smc91x_' variable name prefix to 'smc91c111_' since that's the name of the chip used on the boards; - drop 'AU1XXX_' prefix from the names of macros describing IDE and Ethernet on-board devices; - change 'SMC91111_' to 'SMC91C111_', change 'IRQ' to 'INT' in the names of the macros describing the Ethernet chip for consistency with the IDE macros; - change 'ATA_' to 'IDE_' and 'OFFSET' to 'SHIFT' (since this value is indeed a shift count) in the names of the macros describing the IDE interface.

Instead of allocating pages for the buffer one by one, take advantage of the buddy alloc system and request them 2^order at a time. This increases the chance for bigger buffer parts to be contigious and reduces loop iteration count. While at it, rename function __idetape_kmalloc_stage() to ide_tape_kmalloc_buffer().
