Make the system trusted keyring depend on the asymmetric key type as there's not a lot of point having it if you can't then load asymmetric keys onto it. This requires the ASYMMETRIC_KEY_TYPE to be made a bool, not a tristate, as the Kconfig language doesn't then correctly force ASYMMETRIC_KEY_TYPE to 'y' rather than 'm' if SYSTEM_TRUSTED_KEYRING is 'y'. Making SYSTEM_TRUSTED_KEYRING *select* ASYMMETRIC_KEY_TYPE instead doesn't work as the Kconfig interpreter then wrongly complains about dependency loops.

This option provides support for asymmetric public key type handling.

If signature generation and/or verification are to be used,

appropriate hash algorithms (such as SHA-1) must be available.

ENOPKG will be reported if the requisite algorithm is unavailable.

help
|
|
This option provides a type of key that can be loaded up from a
|
|
PKCS#7 message - provided the message is signed by a trusted key. If
|
|
it is, the PKCS#7 wrapper is discarded and reading the key returns
|
|
just the payload. If it isn't, adding the key will fail with an
|
|
error.

This is intended for testing the PKCS#7 parser.
