    [PATCH] 2.5.7 IDE 25 · e07a6a66
    Martin Dalecki authored
    - Replace the task_io_reg_t with the simple u8. There is no need to obfuscate
       the code more then necessary.
    
    - kill some unnecessary type definitions out from hdreg.h.
    
    - Add proper attributes to register files in hdreg.h.
    
    - Don't use raw arrays for tfRegister and hobRegister in ide_task_s.  Use out
       nice global structures describing the fields in them.  This allows to kill
       the following defines:
    
         IDE_DATA_OFFSET
         IDE_FEATURE_OFFSET
         IDE_NSECTOR_OFFSET
         IDE_SECTOR_OFFSET
         IDE_LCYL_OFFSET
         IDE_HCYL_OFFSET
         IDE_SELECT_OFFSET
         IDE_COMMAND_OFFSET
    
       and many many others.
    
    - Please have a look at the following in pdc4030.c. It couldn't have worked!
       This has been fixed in one go with the above change:
    
       memcpy(args.hobRegister, NULL, sizeof(struct hd_drive_hob_hdr));
    
    - Kill the redundant *_REG_HOB definitions. They don't help readability in any
       way.
