Subject: [PATCH 283/806] tpm: Make SECURITYFS a weak dependency
|
|
|
|
commit 2f7d8dbb11287cbe9da6380ca14ed5d38c9ed91f upstream.
|
|
|
|
While having SECURITYFS enabled for the tpm subsystem is beneficial in
|
|
most cases, it is not strictly necessary to have it enabled at all.
|
|
Especially on platforms without any boot firmware integration of the TPM
|
|
(e.g. raspberry pi) it does not add any value for the tpm subsystem,
|
|
as there is no eventlog present.
|
|
|
|
By turning it from 'select' to 'imply' it still gets selected per
|
|
default, but enables users who want to save some kb of ram by turning
|
|
SECURITYFS off.
