Why I did it
To monitor the SSD health condition in DellEMC S6100 platform post upgrade.
A daemon is introduced to monitor the SSD every one hour.
To check for SSD status at boot time and at the time of cold-reboot.
All these changes are supported only for newer SSD firmware.
Porting changes from 201911 branch
Added a platform_reboot_pre_check script to prevent cold-reboot based on SSD status.
Depends on Azure/sonic-utilities#1556
DO NOT MERGE UNTIL ABOVE PR IS MERGED
Why I did it
Added a check in determining CPU reset in fast-/warm-reboot in their respective platform plugin.
Introducing reboot plugin for "reboot" command to handle its own platform plugin.
How I did it
On branch s6100_fast_warm_check
Changes to be committed:
(use "git reset HEAD ..." to unstage)
modified: ../../debian/platform-modules-s6100.install
modified: ../scripts/fast-reboot_plugin
modified: ../scripts/platform_reboot_override
new file: ../scripts/reboot_plugin
modified: ../scripts/track_reboot_reason.sh
modified: chassis.py
How to verify it
Triggered cold-reset inside fast-reboot to test out the reboot-cause 2.0 API.
Why I did it
serial-getty service exited in Dell S6100 device randomly.
How I did it
Added serial-getty to monit services.
How to verify it
Stop serial-getty in ssh session and check whether the service restarts or not.
#### Why I did it
- To build flashrom properly with dependency tracking.
#### How I did it
- Moved flashrom code from platform/broadcom/sonic-platform-modules-dell/tools directory to src/flashrom directory.
- At the end, flashrom_0.9.7_amd64.deb package is build which will be installed in the devices.
- Currently flashrom builds only for Dell S6100 platforms.

- Why I did it
To collect platform based logs along with "show techsupport" on S6000 and S6100 plaforms.

- How to verify it
hw-mgmt-dump.tar.gz will be found in sonic_dump__< YYYYMMDD_HHMMSS>.tar.gz.
- Make DellEMC platform modules Python3 compliant.
- Change return type of PSU Platform APIs in DellEMC Z9264, S5232 and Thermal Platform APIs in S5232 to 'float'.
- Remove multiple copies of pcisysfs.py.
- PEP8 style changes for utility scripts.
- Build and install Python3 version of sonic_platform package.
- Fix minor Platform API issues.
This common utility would set next boot option as onie mode and
when reboot is triggered it would reboot the box into that specific onie mode.
Current support modes are rescue/install/uninstall
* This method is used to update firmware components such as CPLD,FPGA,BIOS,SMF
* This uses ONIE firmware upgrade design to stage firmware update from NOS.
a) Copy latest firmware updater image to target running sonic.
b) Run “./fw-updater -u onie-firmware-x86_64-dellemc_s5200_c3538-r0.3.40.5.1-9.bin”.
c) This would automatically reboot ONIE into update mode and update firmware components to latest and reboot back to sonic without any user intervention.

The following commit addresses the graceful unmounting of file
system and graceful shutdown of dockers before calling a
cold reboot which will cause a power cycle of SSD. This ensures
orderly shutdown and no corruption of files systems because
of the power cycle to SSD.
This commit will use the existing systemd-reboot service scripts
and override the configuration to do cold reboot for S6100 and
Z9100.
Unit tested the fix and graceful shutdown of file system and
dockers are done with cold reboot.

- 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.
This service (weekly) will let SSD firmware to do the garbage collection
after file-system deleted files. It could avoid slowness or
even READ-ONLY error due to SSD not being able to free the pages
even though the file system thinks there was a lot of space left.
