[PATCH v9 2/6] thunderbolt: Extend NVM version fields to 32-bits

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Szuying Chen <Chloe_Chen@xxxxxxxxxxxxxx>

In order to support non-Intel NVM image formats extend the NVM major and
minor version to 32-bits to better accommondate different versioning
schemes.

No functional impact.
