Remove dependency between SPM_MM and ENABLE_SPM build flags
There are two different implementations of Secure Partition
management in TF-A. One is based on the "Management Mode" (MM)
design, the other is based on the Secure Partition Client Interface
(SPCI) specification. Currently there is a dependency between their
build flags that shouldn't exist, making further development
harder than it should be. This patch removes that
dependency, making the two flags function independently.
Before: ENABLE_SPM=1 is required for using either implementation.
By default, the SPCI-based implementation is enabled and
this is overridden if SPM_MM=1.
After: ENABLE_SPM=1 enables the SPCI-based implementation.
SPM_MM=1 enables the MM-based implementation.
The two build flags are mutually exclusive.
Note that the name of the ENABLE_SPM flag remains a bit
ambiguous - this will be improved in a subsequent patch. For this
patch the intention was to leave the name as-is so that it is
easier to track the changes that were made.
