Browse source 
Updated the Measured Boot PoC to be compliant with the current TF-A
implementation that supports multiple Measured Boot backends, which
are the RSS and Event Log.

@ -5,10 +5,10 @@ Measured Boot is the process of cryptographically measuring the code and
critical data used at boot time, for example using a TPM, so that the
security state can be attested later.
The current implementation of the driver included in Trusted Firmware-A
(TF-A) stores the measurements into a `TCG event log`_ in secure
memory. No other means of recording measurements (such as a discrete TPM) is
supported right now.
The current implementation of the driver included in |TF-A| supports several
backends and each has a different means to store the measurements.
This section focuses on the `TCG event log`_ backend, which stores measurements
in secure memory.
The driver also provides mechanisms to pass the Event Log to normal world if
needed.
