+Diphda Platform
+==========================
+
+Some of the features of the Diphda platform referenced in TF-A include:
+
+- Cortex-A35 application processor (64-bit mode)
+- Secure Enclave
+- GIC-400
+- Trusted Board Boot
+
+Boot Sequence
+-------------
+
+The board boot relies on CoT (chain of trust). The trusted-firmware-a
+BL2 is extracted from the FIP and verified by the Secure Enclave
+processor. BL2 verification relies on the signature area at the
+beginning of the BL2 image. This area is needed by the SecureEnclave
+bootloader.
+
+Then, the application processor is released from reset and starts by
+executing BL2.
+
+BL2 performs the actions described in the trusted-firmware-a TBB design
+document.
+
+Build Procedure (TF-A only)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+- Obtain AArch64 ELF bare-metal target `toolchain <https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-a/downloads>`_.
+ Set the CROSS_COMPILE environment variable to point to the toolchain folder.
+
+- Build TF-A:
+
+ .. code:: shell
+
+ make LD=aarch64-none-elf-ld \
+ CC=aarch64-none-elf-gcc \
+ V=1 \
+ BUILD_BASE=<path to the build folder> \
