+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 'tb_fw_config', '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.
