[DellEMC] S6100 Platform Service optimization (#10989)
Why I did it
- To reduce rc.local script execution time.
- Time consumption of rc.local script is around 22 seconds in S6100.
How I did it
- Moving platform-modules-s6100.service and s6100-lpc-monitor.service asynchronous to rc.local script.
How to verify it
- Load the image with the changes and the time consumption of rc.local script reduced from 22 seconds(approx.) to 14 seconds(approx.) during warm-/fast-reboot upgrades.
- sonic-mgmt test results.

DellEMC S6100 SSD Monitor Porting Changes in 202012 (#8626)
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#1788
DO NOT MERGE UNTIL ABOVE PR IS MERGED

How I did it
On branch s6100_ssd_202012

1b049421aa [DellEMC] Add platform-modules as prerequisite for determine-reboot-cause (#6322)
Add a systemd dependency to make platform-modules service as a prerequisite for determine-reboot-cause service to ensure platform initialization is complete before determine-reboot-cause.service executes.

2e40fa5dbe [devices]: Poller to detect Intel Rangely LPC failure for dell z9100/s6100 (#3065)
- 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.
