#### Why I did it
Add platform_asic file to each platform folder in sonic-device-data package. The file content will be used as the ground truth of mapping from PLATFORM_STRING to switch ASIC family.
One use case of the mapping is to prevent installing a wrong image, which targets for other ASIC platforms. For example, currently we have several ONIE images naming as sonic-*.bin, it's easy to mistakenly install the wrong image. With this mapping built into image, we could fetch the ONIE platform string, and figure out which ASIC it is using, and check we are installing the correct image.
After this PR merged, each platform vendor has to add one mandatory text file `device/PLATFORM_VENDOR/PLATFORM_STRING/platform_asic`, with the content of the platform's switch ASIC family.
I will update https://github.com/Azure/SONiC/wiki/Porting-Guide after this PR is merged.
You can get a list of the ASIC platforms by `ls -b platform | cat`. Currently the options are
```
barefoot
broadcom
cavium
centec
centec-arm64
generic
innovium
marvell
marvell-arm64
marvell-armhf
mellanox
nephos
p4
vs
```
Also support
```
broadcom-dnx
```
#### How I did it
#### How to verify it
Test one image on DUT. And check the folders under `/usr/share/sonic/device`
Depends on Azure/sonic-utilities#1626
Depends on Azure/sonic-swss#1754
QOS tables in config db used ABNF format i.e "[TABLE_NAME|name] to refer fieldvalue to other qos tables.
Example:
Config DB:
"Ethernet92|3": {
"scheduler": "[SCHEDULER|scheduler.1]",
"wred_profile": "[WRED_PROFILE|AZURE_LOSSLESS]"
},
"Ethernet0|0": {
"profile": "[BUFFER_PROFILE|ingress_lossy_profile]"
},
"Ethernet0": {
"dscp_to_tc_map": "[DSCP_TO_TC_MAP|AZURE]",
"pfc_enable": "3,4",
"pfc_to_queue_map": "[MAP_PFC_PRIORITY_TO_QUEUE|AZURE]",
"tc_to_pg_map": "[TC_TO_PRIORITY_GROUP_MAP|AZURE]",
"tc_to_queue_map": "[TC_TO_QUEUE_MAP|AZURE]"
},
This format is not consistent with other DB schema followed in sonic.
And also this reference in DB is not required, This is taken care by YANG "leafref".
Removed this format from all platform files to consistent with other sonic db schema.
Example:
"Ethernet92|3": {
"scheduler": "scheduler.1",
"wred_profile": "AZURE_LOSSLESS"
},

Why I did it
To support dynamic port breakout Broadcom configurations on Arista platforms.
How I did it
Updated platform.json for platforms and added new hwsku, Broadcom config, and hwsku.json for dynamic port breakout usage.
The name of the new hwsku name used is very similar to the platform name (platform x86_64-arista_7050_qx32s hwsku Arista-7050QX-32S) as the flex hwsku is meant to be the default in the future.
How to verify it
Boot up device with the new hwsku, interfaces are up.
Change hwsku.json with new default breakout mode and reload device, breakout will have successfully been applied.
Set hierarchical ecmp level to 2 instead of 3. Based on CS00011833367, ecmp level must be set to 2.
This is already handled for TH2 platforms. Change is required only for TD3

- Why I did it
The pcie configuration file location is under plugin directory not under platform directory.
#6437
- How I did it
Move all pcie.yaml configuration file from plugin to platform directory.
Remove unnecessary timer to start pcie-check.service
Move pcie-check.service to sonic-host-services

Port_config update for hwsku 7050CX3-32S-C3 - add two 10G ports.
This change is added to fix issue of "PortsOrch initialization failure" seen by previous removal of these 10G ports.
Tested on the device with new minigraph, and the PortsOrch initialization failure is not seen.
port_config.ini for HWSKU Arista-7050CX3-32S-C32 has missing speed column and duplicated lanes.
The incorrect speed causes issues in Orchagent RESTARTCHECK as the below task remains as the remaining item during swss shutdown.
Prevent system-healthd from service from failing at boot time due to missing configuration.
Also adds basic support for healthd.
The following caveat exists with this placeholder configuration:
- No PSU monitoring (sensors/fans)
- No ASIC temperature monitoring
platform.json is needed for sonic-mgmt testing. Also in the future it will be used as part of dynamic port breakout.
Also removed the folder symlink for BlackhawkDD because it has a different platform.json than BlackhawkO.

Need A mmu configuration to get the device going without generating lots of warnings.
Similar to dummy MMU configuration for Arista-7050CX3-32S-C32, this configuration will need to be updated with correct numbers. This MMU configuration is copied from 7060 comparable hwsku.
Signed-off-by: Ying Xie <ying.xie@microsoft.com>
- Why I did it
On Arista-7050CX3-32S-C32, there are constant stream of errors like following.
Nov 3 21:56:24.415190 str2-7050cx3-acs-06 NOTICE swss#orchagent: :- registerInWdDb: No lossless TC found on port Ethernet68
Which causes:
loganalyzer to claim test failed.
leaving the system without MMU configuration. Which couldn't be good for any IO test.
- How I did it
Added these MMU configuraions are copied from another platform and guaranteed to be incorrect for hwsku Arista-7050CX3-32S-C32.
Adding them so that we have A MMU configuration and the system won't throw a whole bunch of errors and leave MMU unconfigured. The correct MMU configuration will come later.
This configuration is definitely not suitable for testing system performance or QoS behavior.

- How to verify it
Test will have chance to pass. Ran a few test that would fail otherwise.
- Enable thermalctld support for our platforms
- Fix Chassis.get_num_sfp which had an off by one
- Implement read_eeprom and write_eeprom in SfpBase
- Refactor of Psus and PsuSlots. Psus they are now detected and metadata reported
- Improvements to modular support
