2009-05-11ide: convert to rq pos and nr_sectors accessorsTejun Heo1-1/+1
ide doesn't manipulate request fields anymore and thus all hard and their soft equivalents are always equal. Convert all references to accessors.

2009-04-08ide: refactor tf_load() methodSergei Shtylyov1-3/+4
Simplify tf_load() method, making it deal only with 'struct ide_taskfile' and the validity flags that the upper layer passes, and moving the code that deals with the high order bytes into the only function interested, do_rw_taskfile(). This should stop the needless code duplication in this method and so make it about twice smaller than it was; along with simplifying the setup for the method call, this should save both time and space...

Replace IDE_TFLAG_{IN|OUT}_* flags meaning to the taskfile register validity on input/output by the IDE_VALID_* flags and introduce 4 symmetric 8-bit register validity indicator subfields, 'valid.{input/output}.{tf|hob}', into the 'struct ide_cmd' instead of using the 'tf_flags' field for that purpose (this field can then be turned from 32-bit into 8-bit one).

2009-03-31ide: rename IDE_TFLAG_IN_[HOB_]FEATURESergei Shtylyov1-9/+8
The feature register has never been readable -- when its location is read, one gets the error register value; hence rename IDE_TFLAG_IN_[HOB_]FEATURE into IDE_TFLAG_IN_[HOB_]ERROR and introduce the 'hob_error' field into the 'struct ide_taskfile' (despite the error register not really depending on the HOB bit).

Move apparently misplaced read_sff_dma_status() method from 'struct ide_tp_ops' to 'struct ide_dma_ops', renaming it to dma_sff_read_status() and making only required for SFF-8038i compatible IDE controller drivers (greatly cutting down the number of initializers) as its only user (outside ide-dma-sff.c and such drivers) appears to be ide_pci_check_simplex() which is only called for such controllers...

This is the driver for the Toshiba TX4939 SoC ATA controller. This controller has standard ATA taskfile registers and DMA command/status registers, but the register layout is swapped on big endian. There are some other endian issue and some special registers which requires many custom dma_ops/tp_ops routines and build_dmatable.
