[PATCH v3 11/17] crypto: Kconfig - simplify public-key entries

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

 



Shorten menu titles and make them consistent:
- acronym
- name
- architecture features in parenthesis
- no suffixes like "<something> algorithm", "support", or
  "hardware acceleration", or "optimized"

Simplify help text descriptions, update references, and ensure that
https references are still valid.
