* ide: simplify 'struct ide_taskfile'Sergei Shtylyov2009-04-081-15/+15
| | | | | | | | | | | | Make 'struct ide_taskfile' cover only 8 register values and thus put two such fields ('tf' and 'hob') into 'struct ide_cmd', dropping unnecessary 'tf_array' field from it. This required changing the prototype of ide_get_lba_addr() and ide_tf_dump().

* ide: replace IDE_TFLAG_* flags by IDE_VALID_*Sergei Shtylyov2009-04-081-13/+27
| | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | * Pass number of bytes instead of sectors to ide_init_sg_cmd(). * Pass number of bytes to process to ide_pio_sector() and rename it to ide_pio_bytes(). * Rename ->nsect field to ->nbytes in struct ide_cmd and use ->nbytes, ->nleft and ->cursg_ofs to keep track of number of bytes instead of sectors.
