SCP_BL2 powers up the AP which starts execution at AP_BL31. The AP 17*8445253eSChandni Cherukurithen continues executing and hands off execution to Non-secure world (UEFI). 18*8445253eSChandni Cherukuri 19*8445253eSChandni CherukuriBuild Procedure (TF-A only) 20*8445253eSChandni Cherukuri~~~~~~~~~~~~~~~~~~~~~~~~~~~ 21*8445253eSChandni Cherukuri 22*8445253eSChandni Cherukuri- Obtain arm `toolchain <https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-a/downloads>`_. 23*8445253eSChandni Cherukuri Set the CROSS_COMPILE environment variable to point to the toolchain folder. 24*8445253eSChandni Cherukuri 25*8445253eSChandni Cherukuri- Build TF-A: 26*8445253eSChandni Cherukuri 27*8445253eSChandni Cherukuri .. code:: shell 28*8445253eSChandni Cherukuri 29*8445253eSChandni Cherukuri export CROSS_COMPILE=<path-to-aarch64-gcc>/bin/aarch64-none-elf- 30*8445253eSChandni Cherukuri 31*8445253eSChandni Cherukuri make PLAT=morello all 32*8445253eSChandni Cherukuri 33*8445253eSChandni Cherukuri*Copyright (c) 2020, Arm Limited.
