                              57780, 57760, 57790, 57788


----------------------------
Version 3.19 ---- 6/05/09  
----------------------------   

1. Problem: CQ41770
    can't enable pxe after programming in bootcode 3.18.
   Cause:
    Bootcode 3.18 grew too big and is encroaching upon the stack region.
   Fixed:                                                           
    Shrink code to fit.

Version 3.18 ---- 5/29/09  
----------------------------   

1. Problem: CQ39683
    Cilai detects Receiver Error when the Link Transition between L0s/L0
   Workaround: shorten the delay of the electrical idle signal from serdes
   a. write register 0x7e70 bit [4:0] with 0x0c during device initialization or device reset
   b. write all ones to register 0x110 (correctable error status).
 
2. Enhancement: 
   Checked for Vmain present before access PCI Config Registers.

----------------------------
Version 3.17 ---- 5/18/09  
----------------------------   

1. Enhancement:

----------------------------
Version 3.15 ---- 3/03/09  
----------------------------      

1. Problem: CQ39741
    System can't wake up from LAN when do S1/S3 mode with 57760.
   Cause:
    Phase 1 bootcode for 57760 overlap the Stack region.  Updating Stack will corrupt the Phase 1 bootcode.
    As a result, CPU will stop which will cause system can't wake up from LAN when do S1/S3 mode.
   
   Fixed:
    Reduce Phase 1 bootcode size for 57760 such that it will not overlap with the Stack region.

2. Problem: CQ39706
    Bootcode 3.14 can wake up 57760 on linux system after SUT enter S5 mode
   Cause:
    Phase 1 bootcode for 57760 overlap the Stack region.  Updating Stack will corrupt the Phase 1 bootcode.
    As a result, device may get reset when entering S5 mode and going to OOB state. 
	Since OOB-WOL is enabled, the system will wake up after SUT enter S5 mode.
   
   Fixed:
    Reduce Phase 1 bootcode size for 57760 such that it will not overlap with the Stack region.

3. Enhancement: CQ 39508 update.
    Program the SWR based on OPT 138.

4. Problem: CQ39704
 After 50 iterations of driver load/unload for each speed, 57760A1 failed to bring link up.
   Cause:
    Phase 1 bootcode for 57760 overlap the Stack region.  Updating Stack will corrupt the Phase 1 bootcode.
    As a result, CPU may corrupt system data and cause device to disappear.
   Fixed:
    Reduce Phase 1 bootcode size for 57760 such that it will not overlap with the Stack region.


----------------------------
Version 3.14 ---- 2/24/09  
----------------------------      

1. Problem: CQ39672
    Cilai legacy bootcode v3.13 will fail b57diag c2 test
   
   Cause:
    Phase 1 bootcode overlap the Stack region.  Updating Stack will corrupt the Phase 1 bootcode.
    As a result, CPU will stop which cause b57diag C2 Test to fail.
   
   Fixed:
    Reduce Phase 1 bootcode size such that it will not overlap with the Stack region.

----------------------------
Version 3.13 ---- 2/23/09  
----------------------------      

1. Enhancement:
    Set Reg 0x4400 and Reg 0x4800 to 1 to initialize BufMgr and DMAR if BufMgr is not enabled.	

2. Enhancement: CQ 39508
    Program the SWR based on OPT 138.

----------------------------
Version 3.12 ---- 2/12/09  
----------------------------      
1. Problem: CQ39339
    The Link drop to 10M immediately once NIC Battery Saving Mode in BACS is enabled with AC Power applied.
   
   Cause:
    The issue is due to the current default value of "DisablePowerSaving" is 0 which enabled the reverse nWay feature.
    The reverse nWay feature should not be enabled by default.
   
   Fixed:
    Changed the default value of "DisablePowerSaving" bit in NVRAM to 1 to disable the reverse nWay feature. 
	
2. Problem: 
    Bootcode drive GPIO_0 instead of GPIO_2 when switching power after setting up wol.
   
   Fixed:
    Bootcode will GPIO_2 when switching power after setting up wol.

3. Enhancement:
    Set Reg 0x4400 and Reg 0x4800 to 1 to initialize BufMgr and DMAR.	

4. Enhancement:
    Sets GPHY exp 75 reg vdacctrl bit 0 in GPHY initialization


---------------------------
Version 3.11 ---- 12/18/08  
----------------------------      
1. Enhancement: CQ39027
   Reducing the L0s Exit Latency from 1 uS down to 704 nS.
   1.  Write 7e50 with 0x2c
   2.  Write 7e14 with 0x2c
   3.  Write 44c 241f8400
   4.  Write 44c 24170083

2. Enhancement:
   Disable GPHY APD by the following instructions when the "enable_auto_powerdown" configuration bit is cleared in NVRAM. 
   wr 44c 0x243C941F < This disables DLL Power Down in APD by setting bit 2 in GPHY Register 1C at Shadow 0x5
   wr 44c 0x243CA801  < This disables GPHY APD
   The current code will leave the registers in their default state when the "enable_auto_powerdown" configuration bit is cleared in NVRAM. 

----------------------------
Version 3.10 ---- 12/16/08  
----------------------------

2. Enhancement: CQ 37711
   Adjusted voltage for the 1.2V Rail to 1.20V instead of 1.233V by writing to the following registers:
   1.  Write 36a0 3e0
   2.  Write 36ac 41


----------------------------
Version 3.04 ---- 10/06/08  
----------------------------      

1. Removed workaround: Extended L1 entry time to 4ms to address CQ37120 by writing Reg 0x7d28 with 0x182FFFA for A0 only. 
   This workaround will be done by drivers.


2. Problem: CQ37549
    In normal mission mode, Link Led and Spd1000 Led are always off.
   
   Cause:
    Uart Disable Bit (bit 4) in Reg 0x6808 was cleared by ROM loader.
	In addition, Bootcode and SBROM code will over write the Uart Disable Bit after setting up WOL in NIC mode. 
   
   Fixed:
	Boot code will set Uart Disable Bit (bit 4) in Reg 0x6808 to support LED Mode and preserve the state of the Uart Disable Bit after setting up WOL in NIC mode.  

3. Problem: 
    57780 WOL does not wake up system after unexpected shutdown.
   
   Cause:
    PME Enable Bit (bit 8) of Reg 0x4c is not set.
   
   Fixed:
    Set PME Enable Bit when setting up WOL.  

4. Problem: CQ37691
    Intermittently OTP commands were not executed when they are issued by the internal CPU.  
	As the result the OTP cannot be accessed reliably.
     
  Cause:
    OTP block and the internal may be running in different clock speed. 
	As a result, the OTP block may not be able to receive the commands issued by internal CPU.
  
  Workaround:
    Extend the OTP commands duration such that the OTP commands will not be missed.  This issue will be fixed in B0.

----------------------------
Version 3.03 ---- 9/03/08   (Obsolete)
----------------------------      

1. Extended L1 entry time to 4ms to address CQ37120 by writing Reg 0x7d28 with 0x182FFFA for A0 only. 

----------------------------

----------------------------
1. Modified otp_read function.

2. Updated code according to the SW Programming Guide v1.

----------------------------
