This implements a generic interface towards a Trusted Execution
|
|
Environment (TEE). A TEE is a trusted OS running in some secure
|
|
environment, for example, TrustZone on ARM cpus, or a separate
|
|
secure co-processor etc. See also:

This emulates a generic TEE needed for testing including the AVB
|
|
TA. The emulation provides all callbacks of a regular TEE and
|
|
supports session and shared memory management. The AVB TA is
|
|
emulated with rollback indexes and device lock-state, the state
|
|
of the TA is only kept in RAM and will be reset on each boot.
|
|
The emulation only supports one open session at a time.
|
|
Interaction from the U-Boot command line in possible via the
|
|
"avb" commands.
