Aravind Mani	6c82346c3d	[DellEMC] DMA errors are seen when loading bullseye kernel (#9641) ... Following errors are seen continuously on SMBus controller when loading bullseye kernel.

Qi Luo	add9b651b6	Add platform_asic file to each platform folder in sonic-device-data based package (#8542) ... #### 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`	2021-10-08 19:27:48 -07:00
