This patch adds support for Measured Boot functionality to FVP platform code. It also defines new properties in 'tpm_event_log' node to store Event Log address and it size 'tpm_event_log_sm_addr' 'tpm_event_log_addr' 'tpm_event_log_size' in 'event_log.dtsi' included in 'fvp_tsp_fw_config.dts' and 'fvp_nt_fw_config.dts'. The node and its properties are described in binding document 'docs\components\measured_boot\event_log.rst'.

DTB binding for Event Log properties
|
|
====================================
|
|
|
|
This document describes the device tree format of Event Log properties.
|
|
These properties are not related to a specific platform and can be queried
|
|
from common code.
|
|
|
|
Dynamic configuration for Event Log
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Measured Boot driver expects a *tpm_event_log* node with the following field
|
|
in 'nt_fw_config' and 'tsp_fw_config' DTS files:
|
|
|
|
- compatible [mandatory]
|
|
- value type: <string>
|
|
- Must be the string "arm,tpm_event_log".
|
|
|
|
Then a list of properties representing Event Log configuration, which
|
|
can be used by Measured Boot driver. Each property is named according
|
|
to the information it contains:
|
|
|
|
- tpm_event_log_sm_addr [fvp_nt_fw_config.dts with OP-TEE]
|
|
- value type: <u64>
|
|
- Event Log base address in secure memory.
|
|
|
|
Note. Currently OP-TEE does not support reading DTBs from Secure memory
|
|
and this property should be removed when this feature is supported.
|
|
|
|
- tpm_event_log_addr [mandatory]
|
|
- value type: <u64>
|
|
- Event Log base address in non-secure memory.
|
|
|
|
- tpm_event_log_size [mandatory]
|
|
- value type: <u32>
|
|
- Event Log size.
