Why I did it
There is a need to have separate profiles on compute and storage and this infra update will help achieve that
How I did it
Moved buffer pool/profile and qos definitions on TD2 to a common folder and all TD2 hwsku's will reference that folder
#### 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"
},

* Update default cable len to 0m for TD2 (#8298)
* Update sonic-cfggen tests with the correct cable len
Signed-off-by: Neetha John <nejo@microsoft.com>
As part of the buffer reclamation efforts for TD2, setting the default cable len to 0m which means unused ports will have a cable len of 0m.
Why I did it
To align with the changes in Azure/sonic-swss#1830
How to verify it
- With the default cable len set to 0m and the associated changes in swss, CABLE_LENGTH table had '0m' set for unused ports and accordingly more space was reserved for the shared pool
- Cfggen tests passed with the cable len update

This change introduces dynamic port breakout (DPB) for Arista 7050 QX32 model by adding a new SKU suffixed with `-Flex`.
The breakout configuration allowed is the same as in mainline Arista EOS, i.e. 24 first ports are allowed to be used in 4x10G in addition to the default 40G mode. The last 8 ports are fixed to 40G. This is due to ASIC limitations of a total of 104 max ports.
**NOTE**: As described in https://github.com/aristanetworks/sonic/issues/30#issuecomment-820584113 front panel LEDs are likely not working when operating in breakout mode. It is not clear if the LEDs work correctly in 40G mode as I have not had a chance to physically inspect the switch with this patch.

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.

* Fix showing systemd shutdown sequence when verbose is set
* Fix creation of kernel-cmdline file
Sometimes boot0 prints error
"mv: can't preserve ownership of '/mnt/flash/image-arsonic.xxxx/kernel-cmdline': Operation not permitted"
* Improve flash space usage during installation
Some older systems only have 2GB of flash available. Installing a second
image on these can prove to be challenging.
The new installation process moves the installer swi to memory in order
to avoid free up space from the flash before uncompressing it there.
It removes all the flash space usage spike and also improves the IO
since the installation is no more reading and writting to the flash at
the same time.
