| 2 | ================ |
| 3 | |
| 4 | Morello is an ARMv8-A platform that implements the capability architecture extension. |
| 5 | The platform port present at `site <https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git>`_ |
| 6 | provides ARMv8-A architecture enablement. |
| 7 | |
| 8 | Capability architecture specific changes will be added `here <https://git.morello-project.org/morello>`_ |
| 9 | |
| 10 | Further information on Morello Platform is available at `info <https://developer.arm.com/architectures/cpu-architecture/a-profile/morello>`_ |

| 12 | Boot Sequence |
| 13 | ------------- |
| 14 | |
| 15 | The execution begins from SCP_BL1 which loads the SCP_BL2 and starts its |
| 16 | execution. SCP_BL2 powers up the AP which starts execution at AP_BL31. The AP |
| 17 | then continues executing and hands off execution to Non-secure world (UEFI). |

| 19 | Build Procedure (TF-A only) |
| 20 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
| 21 | |
| 22 | - Obtain arm `toolchain <https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-a/downloads>`_. |
| 23 | Set the CROSS_COMPILE environment variable to point to the toolchain folder. |
| 24 | |
| 25 | - Build TF-A: |
| 26 | |
| 27 | .. code:: shell |
| 28 | |
| 29 | export CROSS_COMPILE=<path-to-aarch64-gcc>/bin/aarch64-none-elf- |
| 30 | |
| 31 | make PLAT=morello all |
