Allowing access to the MM SP services (SPs such as StandAlonneMM, smm-gateway).
When using the u-boot OP-TEE driver, StandAlonneMM is supported.
When using the u-boot FF-A driver any MM SP is supported.
If OP-TEE is present and running StandAloneMM, dispatch all UEFI
variable related operations to that. The application will verify,
authenticate and store the variables on an RPMB.
When ARM_FFA_TRANSPORT is used, dispatch all UEFI variable related
operations to the MM SP running in the secure world.
A door bell mechanism is used to notify the SP when there is data in the shared
MM buffer. The data is copied by u-boot to the shared buffer before issuing
the door bell event.

help
This defines the size in bytes of the memory area reserved for the shared
buffer used for communication between the MM feature in U-Boot and
the MM SP in secure world.
The size of the memory region must be a multiple of the size of the maximum
translation granule size that is specified in the ID_AA64MMFR0_EL1 System register.
It is assumed that the MM SP knows the size of the shared MM communication buffer.
