  25  * SCSI I2O host adapter driver
  26  *
  27  *      V1.08 2001/08/21 Mark_Salyzyn@adaptec.com
  28  *              - The 2000S and 2005S do not initialize on some machines,
  29  *                increased timeout to 255ms from 50ms for the StatusGet
  30  *                command.
  31  *      V1.07 2001/05/22 Mark_Salyzyn@adaptec.com
  32  *              - I knew this one was too good to be true. The error return
  33  *                on ioctl commands needs to be compared to CAM_REQ_CMP, not
  34  *                to the bit masked status.
  35  *      V1.06 2001/05/08 Mark_Salyzyn@adaptec.com
  36  *              - The 2005S that was supported is affectionately called the
  37  *                Conjoined BAR Firmware. In order to support RAID-5 in a
  38  *                16MB low-cost configuration, Firmware was forced to go
  39  *                to a Split BAR Firmware. This requires a separate IOP and
  40  *                Messaging base address.
  41  *      V1.05 2001/04/25 Mark_Salyzyn@adaptec.com
  42  *              - Handle support for 2005S Zero Channel RAID solution.
  43  *              - System locked up if the Adapter locked up. Do not try
  44  *                to send other commands if the resetIOP command fails. The
  45  *                fail outstanding command discovery loop was flawed as the
  46  *                removal of the command from the list prevented discovering
  47  *                all the commands.
  48  *              - Comment changes to clarify driver.
  49  *              - SysInfo searched for an EATA SmartROM, not an I2O SmartROM.
  50  *              - We do not use the AC_FOUND_DEV event because of I2O.
  51  *                Removed asr_async.
  52  *      V1.04 2000/09/22 Mark_Salyzyn@adaptec.com, msmith@freebsd.org,
  53  *                       lampa@fee.vutbr.cz and Scott_Long@adaptec.com.
  54  *              - Removed support for PM1554, PM2554 and PM2654 in Mode-0
  55  *                mode as this is confused with competitor adapters in run
  56  *                mode.
  57  *              - critical locking needed in ASR_ccbAdd and ASR_ccbRemove
  58  *                to prevent operating system panic.
  59  *              - moved default major number to 154 from 97.
  60  *      V1.03 2000/07/12 Mark_Salyzyn@adaptec.com
  61  *              - The controller is not actually an ASR (Adaptec SCSI RAID)
  62  *                series that is visible, it's more of an internal code name.
  63  *                remove any visible references within reason for now.
  64  *              - bus_ptr->LUN was not correctly zeroed when initially
  65  *                allocated causing a possible panic of the operating system
  66  *                during boot.
  67  *      V1.02 2000/06/26 Mark_Salyzyn@adaptec.com
  68  *              - Code always fails for ASR_getTid affecting performance.
  69  *              - initiated a set of changes that resulted from a formal
  70  *                code inspection by Mark_Salyzyn@adaptec.com,
  71  *                George_Dake@adaptec.com, Jeff_Zeak@adaptec.com,
  72  *                Martin_Wilson@adaptec.com and Vincent_Trandoan@adaptec.com.
  73  *                Their findings were focussed on the LCT & TID handler, and
  74  *                all resulting changes were to improve code readability,
  75  *                consistency or have a positive effect on performance.
  76  *      V1.01 2000/06/14 Mark_Salyzyn@adaptec.com
  77  *              - Passthrough returned an incorrect error.
  78  *              - Passthrough did not migrate the intrinsic scsi layer wakeup
  79  *                on command completion.
  80  *              - generate control device nodes using make_dev and delete_dev.
  81  *              - Performance affected by TID caching reallocing.
  82  *              - Made suggested changes by Justin_Gibbs@adaptec.com
  83  *                      - use splcam instead of splbio.
  84  *                      - use u_int8_t instead of u_char.
  85  *                      - use u_int16_t instead of u_short.
  86  *                      - use u_int32_t instead of u_long where appropriate.
  87  *                      - use 64 bit context handler instead of 32 bit.
  88  *                      - create_ccb should only allocate the worst case
  89  *                        requirements for the driver since CAM may evolve
  90  *                        making union ccb much larger than needed here.
  91  *                        renamed create_ccb to asr_alloc_ccb.
  92  *                      - go nutz justifying all debug prints as macros
  93  *                        defined at the top and remove unsightly ifdefs.
  94  *                      - INLINE STATIC viewed as confusing. Historically
  95  *                        utilized to affect code performance and debug
  96  *                        issues in OS, Compiler or OEM specific situations.
  97  *      V1.00 2000/05/31 Mark_Salyzyn@adaptec.com
  98  *              - Ported from FreeBSD 2.2.X DPT I2O driver.
  99  *                      changed struct scsi_xfer to union ccb/struct ccb_hdr
 100  *                      changed variable name xs to ccb
 101  *                      changed struct scsi_link to struct cam_path
 102  *                      changed struct scsibus_data to struct cam_sim
 103  *                      stopped using fordriver for holding on to the TID
 104  *                      use proprietary packet creation instead of scsi_inquire
 105  *                      CAM layer sends synchronize commands.
