- What I did
Added Daemon to Log LPC bus degradation in Intel C2000 processor. Intel Rangeley C2000 processors with revision less than or equal to 2 have issue where LPC bus degrades over time in some processors. To identify the problem and to notify the issue, a daemon has been added which will log on encountering the issue.
- How I did it
Added a daemon which validates the CPLD scratch(0x102) and SMF scratch(0x202) registers by writing and reading values on regular polling intervals (300 seconds). If there is a discrepancy between read and write, a critical log will be thrown.
- How to verify it
The infra is verify by simulating the issue where between write and read, the value in register is modified and the log appearance is checked.
- Description for the changelog
Added Daemon to identify LPC bus degradation issue and notify using syslog in Dell S6100 and Z9100 platforms. This daemon will only run on processors with revision less than or equal to 2.
Rely on platform= and sid= on the command line to detect the platform rather than the eeprom
The platform will now properly initialize even if the system eeprom died or is unreachable.
Add support for the 7260CX3-64E
This is a variant of the 7260CX3-64 with no real difference for software.
* Remove the divide by 4 operation to the under the hood SAI
This is to avoid the need and thus the confusion for application program to know
the mmu internal architecture
This change must have support from SAI change to reach the correct
config

2) Install debug tools in every debug docker image
3) Install available debug symbols in debug docker image
4) Provide additional host/docker mapping for host dirs /src & /debug
4.1) The one-image will have source code under /src
4.2) /debug is mapped as rw. User can put his core file there and use this dir to
collect debug session logs too.
5) Build debug image using debug dockers
6) Source code is archived into /src of debug image
7) The welcome banner is extended to display these additional facilities in debug image.
* [submodule] update sonic-linux-kernel (#2985)
* Fix many version strings
* Update minor version
* Update arista-drivers submodule (#9)
* Rebuild SDK on new kernel (#10)

dell_ich module fails to load sometimes due to the failure of pci_get_drvdata().
This function is responsible for fetching INTEL PCI related memory handle in kernel. This is implemented in lpc_ich kernel module.
Due to race in addition/deletion of kernel modules, sometimes lpc_ich loads after dell_ich.
Because of this behaviour dell_ich module fails to load.
Fixed by addding dependency between modules.
Removed i2c_mux_gpio module from blacklist entry as it is not the original root case of this issue.
- Include helix4 fix.
- Include support for TD2 56854.
- Add dummy support for SAI_PORT_ATTR_ADVERTISED_SPEED.
