Jade/Caesar Selfboot Patch For Chip Rev. A2
-------------------------------------------
5787, 5787m, 5787f, 5754, 5754m
----------------------------
Version 2.09 ---- 11/13/06
----------------------------
1. Compiler Error
Problem: CQ#27433
NIC is no longer recognized by b57diag and Windows after update selfboot
version 2.08.
Cause:
The compiler for version 2.08 was not completed for 5787/5787f/5754/5754m.
This incorrect image will cause device disappeared after download.
Notes:
Version 2.08 was removed from release directory.
----------------------------
Version 2.08 ---- 11/09/06
----------------------------
1. PCIE Link Polarity
Enhancement: CQ#27039, CQ#26767, CQ#27105
Apply PCIE Link polarity workaround only at hardware reset (POR or
PEReset).
2. Improve PCIE SerDes PLL Power Down Feature in conjunction with clkreq being enabled.
Enhancement: CQ#27236
Poll the actual clkreq state at 0x68A4[2]:
a. If 0x68A4[2]=1, then enables PLL power down by writing 0x7d54 with 0x7000.
b. if 0x68a4[2]=0 and port is link down, then disables PLL power down by
writing 0x7d54 with 0x7080.
Note:
This enhancement is only applicable to 5787M.
Need to use version 10.05.04 or later version of b57diag program to enable/disable
this feature.
3. Increase the Fast Training Sequence(FTS) timming
Problem: CQ14315
If L0s is enabled on the BRCM chip a "yellow bang", or a system hang
condition can occur.
Cause:
During the L0s to L0 exit transition, symbol lock can be lost if the
system reference clock has not fully stabilized what leads the PCI-E
link training state machine to go through the "detect" state. Going
through "detect" causes an internal reset to the BRCM chip what causes
"yellow bang" and/or a system hang condition based on the chipset
configuration.
Fix:
1. Change Serdes RX Timer from 768 ns to 2 uS to make sure the
Serdes CDR is stable before it sends data to the Physical Layer.
2. Increase FTS Count from 1uS to 2.25 uS to avoid intermittent GRC
Reset when L0s is enabled.
Since RX Timer value and FTS Count change only needed before PCIE link
training, bootcode will initialize those values and retrain the PCIE
link during cold reset only. When driver reset, this workaround is
bypassed to avoid PCIE link retrain.
Impact:
Increasing the amount of FTS required to transition from L0s to L0,
performance impact between 1uS to 2.25uS is un-noticeable.
----------------------------
Version 2.07 ---- 10/10/06
----------------------------
1. L1 exit latency improvement
Enhancement: CQ#27044
Improve the L1 exit latency when Clock Request is enabled.
Note:
No change for non-Mobile parts.
2. Enable Clock Request
Enhancement: CQ#26951
The clock request was disabled in version 2.06 for CQ #26629.
Change to use h/w default setting.
----------------------
Version 2.06 9/20/06
----------------------
1. Disable Clock Request
Enhancement: CQ#26629
The clock request enabled feature is not fully tested. This feature needs
to be disabled for RC 10.0 release.
Note:
The ClockReq is automatically disabled by h/w on a non-Mobile parts; therefore,
this change does not affect non-Mobile parts.
----------------------
Version 2.05 8/18/06
----------------------
1. Removed disabling of ClkReq.
Enhancement: CQ26097
Per project lead's decision, the feature was disabled before validation.
However, without enabling it, PQA will not be able to test it. Therefore,
we will enable this feature.
Change:
The change is made so firmware will not touching register 0xdc. The value
to advertise ClkReq feature will be based on the hardware default.
The ClkReq is enabled only in Mobil devices.
Impact:
Bootcode's change may also get over written. Updated driver should be used
to ensure the function is enabled. (Refer to CQ26098 to find out the
correct driver version that address this issue.)
2. Cable Sense Support
Problem:
The GPhy was shutdown even if the cable sense mode is enabled.
Cause:
Coding error
Fix:
Changed the code so it does not power down the Gphy if cable
sense mode is enabled.
----------------------
Version 2.04 3/31/06
----------------------
1. Changed SSID
Enhancement: CQ#23848
For Jade devices, bit-15 of SSID needs to be set to 1.
There is no impact/change for Caesar devices.
2. Initialized Cardbus pointer register
Enhancement: CQ#23431
Since Cardbus support is no longer a requirement, in order to pass
the plug-fest compliance test, we write zero to register 0x28 to disable
cardbus feature.
----------------------
Version 2.03 2/09/06
----------------------
1. Enable PEReset Mask
Problem:
CQ#23039:
On certain systems, when entering S5 state (with WoL enabled), the
LOM current draw on the 1.2V rail can fluctuate between ~90mA and
~150mA from shutdown to shutdown.
CQ#22684:
On certain systems (with WoL enabled), the 5754/A1 LOM may disappear
during repeated S5 Power-Cycle tests.
Cause:
As part of the bootcode f/w logic, the NIC f/w will make access to
certain registers (0x00-0xff and 0x7c00-0x7fff) when the firmware
detected that the Vmain power goes low. Due to CQ23039, the register
bit that the firmware used for detecting the "Vmain power state" can
also toggles between logical '0' and '1', and this leads to f/w to not
able to make reliable read/write access to the registers (0x00-0xff and
0x7c00-0x7fff), which ultimately causes bad behaviors that is described
in CQ22684.
Fix:
Firmware now enables the PEReset Mask register bit (0x68a4[16]=1). By
enabling this register bit, the chip exits the reset state after the
current fluctuation become stabilized, which eliminates the toggling of
the "Vmain power" detection register bit, which ultimately enables
successful access to the register (0x00-0xff, 0x7c00-0x7fff) by the f/w.
Impact:
Fixes CQ#23039 and CQ#22684.
----------------------------
Version 2.02 ---- 1/24/06
----------------------------
1. Changed CQ#22832 fix
Problem: CQ#22832
The CQ#22832 request to change 0x7d00 access to read-modify-write still
have problem on some system when reference clock is not stable.
Cause:
Absolute-write may corrupt register 0x7D00 content under corner conditions.
Fix:
Changed to code to not to touch 0x7d00 at all.
Impact:
There is no impact if the WOL feature is not enabled in our device. There
is also no impact if the system always broadcasts PME_Turn_Off tlp message
to downstream before it removed the main power in system OOB or hibernate
scenario.
There is little power consumption increase when a) WOL is enabled in our
device and b) the system ungracefully removes the main power without
sending out PME_Turn_Off tlp message to downstream in system OOB or
hibernate scenario. The current draw in our device is measured at 236mA
as compared to 172mA before this change.
Since there is no more 0x7d00 access, version 2.01, #2 (Enabled ASIC
fix for CQ#11011), is undone. Using hardware default value.
2. Enabled ASIC fix for tx Ethernet packet corruption on late collision
Enhancement: CQ#22908, CQ#14561, CQ#14521
Since the ASIC is fixed and verified by ASIC team, we are enabling the
fix in this version.
----------------------
Version 2.01 1/18/06
----------------------
1. Changed 0x7d00 access to absolute write
Problem: CQ#22832
A value of 0xa000 was left in register 0x7d00 and caused the device to
disappear in some systems.
Cause:
When the device was put into D3 power state, due to the clock issue, the
PCIE registers become not accessible. If read-modify-write were used at
this point, the read will fail and returning zero to CPU. Then, after
CPU modify the content and write back, many critical bits are cleared in
register 0x7d00. As result, the subsequence reset, the device could not
establish PCIE link and disappears from the host.
Fix:
Changed 0x7d00 register to absolute write instead of read-modify-write.
2. Enabled ASIC fix for CQ#11011
Enhancement:
The decision has been made to enable this ASIC fix to be consistent with
Shasta/Baxter. This is done by clearing bit 18 of 0x7d00.
3. Removed clkreq advertisement
Enhancement: CQ#22829
Until ASIC teams verifies this function, we will disable feature for now.
