Sorry for jumping in again after not participating in the discussion for

What happened to my suggestion of making this a platform-independent
interface to avoid the link time dependency?

Specifically, why not add an exported function to drivers/base/soc.c that
uses glob_match() for comparing a string in the device driver to the ID
of the SoC that is set by whatever SoC identifying driver the platform
has?

[Lu Yangbo-B47093] I think this has been discussed in v6.
You can find Scott's comments about this in below link.
