Changes to support building MM images in secure and normal worlds on FVP- AEMv8-AEMv8.
Management Mode (MM) provides a secure execution environment on Server and Clamshell platforms. It is specified in the Volume 4. PI specification. An implementation exists in the EDK2-Staging code base. In order to support MM on ARM, changes are required to both EDK2 and ARM Trusted Firmware. MM provides a management service rather than a security service. Hence it has to be isolated from any software stack e.g. Trusted OS that provides security services. The MM Image executes in S-EL0 on ARM platforms in a sandboxed environment. In future, there might be other sandboxed environments that co-exist with it. Each sandbox implements a Secure Firmware Service. The corresponding image is called a SFS_PAYLOAD.
This change adds an optional parameter ATF_SFS_PAYLOAD. ATF_SFS_PAYLOAD will be the path to management service in fd format (EDK2 Firmware Device).
Signed-off-by: Supreeth Venkatesh supreeth.venkatesh@arm.com --- Changes in v4: - Cosmetic Name Changes. fvp_normal_mm -> fvp_mm_normal and fvp_secure_mm to fvp_mm_standalone. Changes in v3: - Add ARM_STANDALONE_MM_ENABLE=TRUE for normal MM Image in platforms.config. Changes in v2: - Updated Commit Message to indicate concept of Secure Firmware Services is still in flux. - Changed internal variable in atf_build.sh file to SFS_OPTION from SFS_PAYLOAD. - Drop FIRMWARE_VER parameter for fvp_normal_mm platform. --- atf-build.sh | 14 ++++++++++++-- platforms.config | 22 ++++++++++++++++++++++ 2 files changed, 34 insertions(+), 2 deletions(-)
